of 12 Laroflex MP 45 grades

Application

Laroflex MP 45 grades are binders resistant to hydrolysis. They can beused for anti-corrosion coatings, for coatings on galvanized steel,other non-ferrous metals, concrete, fiber cement, for road markingpaints, flame-retardant coatings on non-flammable building materials, printing inks, marine and container paints. They are compatiblewith most alkyd resins, dry oils, polyacrylic resins, liquid epoxy resins, tars and bitumens.

Overview Laroflex MP 45 grades offer advantages to both manufacturers andusers of coatings:

• broad choice of solvents, particularly budget-priced blends ofaromatic and aliphatic hydrocarbons

• good compatibility with other coatings raw materials

• good pigment binding capacity even at high solids

• unrestricted choice of pigments and extenders

• easy application by all common techniques, no cob-webbingeven at high solids

• thermal stability allows force drying

• good adhesion on iron, steel and many unrelated coatings systems, good intercoat adhesion

• good resistance of properly formulated coatings to aqueousalkalis and acids, salt solutions, to stress from water, humiditychanges, low and cyclic temperatures as well as to chalkingand yellowing

• long lasting corrosion protection even under extreme outdoorconditions

Differences in properties Laroflex MP 45 grades mainly differ in their viscosities and the rheology of their solutions. Viscosity ranges given in the table relate to20 % solutions in toluene at 23 °C (73 °F). The less polar the solvent,the greater the differences in viscosity.

The low-viscous solutions of Laroflex MP 45 and Laroflex MP 45are diluted easiest with aliphatic hydrocarbons, their viscositychanges the least during storage and they produce highest gloss.

The high-viscous solutions of Laroflex MP 45 tend to gel, particularly in non-polar solvents.

Choosing the right solvent Suitable solvents are aromatic hydrocarbons or their blends withesters and glycolether acetates. Aliphatic hydrocarbons and/oralcohols are used as diluents.

Ketones, in general, are less suited since they are retained by vinylchloride polymers longer than other solvents with equal volatility,resulting in slower drying coatings. 12 Laroflex MP 45 grades

The diluent fraction of the solvent blend mainly depends on the solvency of the true solvent. Depending on the type of solvent andwhen Laroflex MP 45 or Laroflex MP 45 are used, the diluentproportion must be reduced by up to 40 % as compared with Laroflex MP 45.

The diluent proportion can be increased if other raw materials inthe formulation are readily compatible with Laroflex MP 45 gradesand soluble in aliphatic hydrocarbons or alcohols. Examples arehard resins such as Laropal K 80, many alkyd resins, higharomatic grades of tar, soft resins and plasticizers present ingreater proportions.Aromatic hydrocarbons or blends of aromatic and aliphatic hydrocarbons are best suitable for coatings that are to be exposed towater very soon after application.High-volatile solvents and/or diluents produce faster drying coatings.Coatings containing a blend of xylene and butanol instead of xylenealone will dry faster. Polymers release esters more easily than ketones and aromatic hydrocarbons of the same volatility. The mostfavorable low-volatile solvent is ethoxypropyl acetate. Note that thesolvent retention also depends on the other constituents of theformulation.

Gloss and flow of coatings can be improved by adding high-boilingsolvents, e.g., ethoxypropyl acetate. High proportions of low-volatilediluents, however, may result in precipitating of binder constituents,impairing both gloss and mechanical properties of the coatings.

Greater proportions (20–25 %) of high-boiling solvents, e.g., ethoxypropyl acetate or blends of aromatic hydrocarbons with a boilingrange of 150 °C (302 °F) to 190 °C (374 °F) reduceblistering whichmay occur in airless-sprayed coatings, particularly those with a lowpigment content.High proportions of diluent in the solvent blend reduce the risk ofprevious coats pulling up.

Clear or almost clear solutions can be obtained in aromatic hydrocarbons such as toluene, xylene or Solvesso1 100 as well as inchlorinated hydrocarbons, anone and tetrahydrofuran. Solutionswith other solvents may be somewhat cloudy but will not adverselyinfluence hardness and homogeneity of the film, provided the solution dries to form a clear film.

Viscosity behavior of the solution The viscosity of solutions of Laroflex MP 45 grades not only dependson the concentration, the composition of the solvent blend and itstemperature, but also on the conditions under which they are prepared.registered trademark of Exxon Mobil Corporation of 12 Laroflex MP 45 grades The higher the temperature as well as duration and extent of shearforces, the lower the viscosity of the solution will be after coolingdown to room temperature. After extended storage, the viscositymay increase again, an effect that is more pronounced the less thesolvating power and the affinity between solvents and polymer.

Unpigmented concentrated solutions of Laroflex MP 45 grades inxylene may tend to gel – often only months after they have beenprepared and without undergoing a gradual increase in viscosity.

Adding ketones and esters reduces the tendency to gel, in particular if the binder concentration is high. By adding 10–20 % of analcohol to the solvent blend, gelling generally can be suppressedcompletely. Likewise, no gelling has been observed yet in formulations containing blends of high-boiling aromatics such asby intensive stirring, heating or by milling with pigments.

This rheological behavior is quite pronounced in Laroflex MP 45. Itis scarcely noticed in Laroflex MP 45 and not at all in Laroflex MP 45 and Laroflex MP 45.

Plasticizing Laroflex MP 45 grades are internally plasticized. Coatings based on

4 F) or polyester resins in larger proportions of 15–30 %.

In formulations based on Laroflex MP 45, the plasticizer propotion should be kept some 10–15 % lower than in those based onthe other Laroflex MP 45 grades.

Too much plasticizer will adversely affect the hardness and thermostability of the dried coatings and can promote shrinkage, alligatoring and soiling of outdoor coatings.

Coatings that have to withstand chemicals and salt water are formulated with plasticizers resistant to saponification, e.g., chlorinated paraffin waxes. Saponifiable plasticizers (phthalates, adulatesor phosphates) can be used when resistance to chemicals is lessimportant. Plastigen G is the plasticizer of choice for coatings onalkaline substrates (e.g., concrete) and for top coats extraordinarilyresistant to yellowing and chalking. Laroflex MP 45 gradesAcronal 4 F and its mixtures with phthalates are particularly suitable to increaseadhesion to aluminum and its alloys and otherdifficult substrates. The flexibility and adhesion of films based on Laroflex MP 45 grades at low temperatures can be increased by using low-viscosity, high-efficiency plasticizers (Palatinol 911 andPlastomoll DOA). Plasticizers which are insoluble in aliphatic hydrocarbons (Palamoll 646) least impair the resistance of filmsbased on Laroflex MP 45 grades to lubricants and fuel oil.Modification by other coatings raw materialsHard resins

Solids content, gloss and adhesion can be increased by adding hard resins.Non-saponifiable hard resins such as Laropal K 80 are recommended for coatings resistant to chemicals and water. For nonpale coatings or when less emphasis is put on resistance to light and weathering, coumarone, indene or hydrocarbon resins can beused. Saponifiable hard resins (e.g., maleate or modified phenolicresins) can be used if good resistance to chemicals is not required.Hard resins which are compatible with Laroflex MP 45 grades (e.g.,Laropal K 80 or Laropal A 81) are often able to overcome anyslight incompatibility on the part of other materials present in theformulation. Laropal K 80 and Laropal A 81 increase the diluenttolerance of coatings based on Laroflex MP 45 grades for aliphatic hydrocarbons.Air-drying bindersAir-drying binders reduce the thermoplasticity of Laroflex MP 45 grades.Combined with a predominant proportion of air-drying binder,Laroflex MP 45 grades improve the coating’s

• surface drying and thus its initial hardness,

• resistance to chemicals and water,

• outdoor performance, particularly in industrial environments.

If resistance to chemicals and water is essential, the proportion of

Laroflex MP 45 should be at least the same as that of the air-drying binder.

The lower acid value and average molecular mass of an alkyd resin,

the better its compatibility – which should be checked in each case.

The most compatible alkyd resins are those containing about 45– 55 % drying or 25–50 % semidrying oils.

Other compatible binders are bodied oils with modified phenolic

resins, various urethane/alkyd resins and some epoxy resins modified by oil fatty acids.

12 Laroflex MP 45 grades

In many cases, air-drying binders can be made perfectly compatible with Laroflex MP 45 grades by including other compatible components, e.g., Laropal K 80, Laropal A 81 or plasticizers.

In combinations of Laroflex MP 45 grades with alkyd resins, theamount of white spirit in the solvent blend can often be increasedwell above the proportion normally used in coatings solely containing Laroflex MP 45 grades (see Typical solvent blends earlier in this chapter).

If these “hybrid binder” coatings are to be overcoated, care must betaken to ensure that oxidative drying has progressed so far thatthere is no risk of “pulling up” caused by excessive softening of thefirst coat by the solvent phase of the second coat. The tendency ofpulling up can be reduced by increasing the proportion of Laroflex MP 45 grades. Equally, the solvent can be diluted with more whitespirit. Solvent blends whose proportion of diluents increases gradually and only to a limited extent perform best. An example is a blendconsisting of equal parts of xylene and white spirit.

Pigmentation Any conventional anti-corrosion pigment can be used in primersbased on Laroflex MP 45 grades as chemical reactions between thetwo are unlikely. Based on our current experience, the binder – ifstored under normal conditions – does not need to be stabilizedagainst attack by active metal powders such as aluminum bronze.

If there are any doubts, small proportions of zinc oxide or epoxycompounds may be added. registered trademark of Resolution Nederland B. V.

Laroflex MP 45 grades

Higher proportions of flake extenders or pigments in the pigmentblend (e.g., talc, micaceous iron oxide or aluminum bronze) improve the coatings’ adhesion and impermeability to water vapor,they also facilitate airless spraying of thick coats.

Pigments and extenders resistant to weathering should be preferredfor topcoats. Some extenders – including a few natural magnesium,aluminum or potassium-aluminum silicates as well as barytes –contain impurities, which may cause yellowing of white topcoats. Asmall amount of zinc white generally prevents such discoloration.

Pigments resistant to acids and alkalis must be used for coatingsresistant to chemicals.

Effective corrosion protection is achieved with coatings having apigment volume concentration (PVC) of 16–35 %. For coatingsparticularly resistant to chemicals, a lower PVC range of 16–22 %should be preferred. Well-formulated high-build finishes, on theother hand, can be pigmented up to about 35 %. In general, thepigmentation level should be limited to 90 % of the critical PVC.

Stabilizers Laroflex MP 45 grades are sufficiently stable to dehydrochlorination.

Thus no stabilizers are normally needed. Exceptions are coatingsthat are either exposed to heat or unpigmented or – in some casesof coatings based on transparent pigments – exposed to UV radiation for extended periods.

Note that chlorinated binders are less stable if moisture or somechemicals are present.

Generally, coatings systems based on Laroflex MP 45 grades shouldnot be exposed to heat above 70–80 °C (158–176 °F) for prolongedperiods.Heat stabilizers should be added for force drying at temperatures ofup to 130 °C (266 °F). Adding 2 % Mark®4 17 M and 3 % Drapex439 (respective to Laroflex MP 45) provides adequate stabilization.

Dispersants,antisettling agents,thixotropes

Some dispersants or antisettling agents, particularly in higher proportions, may act with chlorinated binders to cause corrosion ofmetal containers and thus reduce the coating’s anticorrosion protection. Trials are recommended.

Thixotropes derived from hydrogenated castor oil (e.g., Luvotix5 or

Thixatrol6 ST) can be used for high-build coatings. Manufacturer’s

instructions on their use should be observed. registered trademark of Crompton Vinyl Additives registered registered trademark of Elementis plc 12 Laroflex MP 45 grades

Further, suitable thickeners and antisettling agents consist of anapproximately 10 % gel paste made from Bentone®6 38 or Bentone®639 and Anti-Terra®7 U in aromatic solvents.

Processing Production of coatings

Laroflex MP 45 grades dissolve very rapidly even without heating.

Caking is avoided by immediately and uniformly distributing thepowder: thoroughly stirring, it is slowly added to the diluent (aliphatic hydrocarbons, alcohols). Proportions of Laroflex MP 45 powder and diluent should be approximately equal. Then, solvent(s)and other diluents are added while stirring. Subsequently, plasticizers and combination resins may be added.

Solutions of Laroflex MP 45 grades that contain plasticizers and possibly other binder components are used to paste and mill pigments. If alkyd resin cobinders are present in the formulation, thesecan be used to prepare the pigment paste.

Application techniques

Coatings based on Laroflex MP 45 grades are suitable for all common application techniques such as high-pressure spraying, airlessspraying, hot spraying, brushing, dipping, curtain or roller coatingor paint roller.

No cob webbing occurs during the application of coatings basedon Laroflex MP 45 grades even at high solids or if they contain highlyvolatile solvents.

Blistering and pore formation during airless spraying can beavoided by keeping the proportion of highly volatile esters (e.g.,ethyl acetate and butyl acetate) in the solvent blend low. The inclusion of high-boiling aromatic hydrocarbons or ethoxypropyl acetatein advantageous. Good results are also obtained with defoamers,especially in paints with low PVC.

Drying

Coatings based on Laroflex MP 45 grades surface-dry rapidly butrequire some length of time to through-dry since Laroflex MP 45grades, like all polymers, tend to hold back residual solvent. Consequently, a drying time of one or two days should be left betweencoats to prevent pulling up. Coatings to be exposed to water orliquid chemicals must be allowed to through-dry thoroughly. In thiscase, polar solvents should be avoided as any residual solventcould absorb large amounts of water and cause swelling.

Drying time can be reduced by choosing suitable solvent blends,reducing the plasticizer proportion, a higher PVC or adding voluminous extenders or diatomite. Excessive quantities of these extenders and inadequate pigment dispersion can easily lead to porouscoatings with greater permeability to water vapor.

Fields of application Industrial corrosion protection

Combinations of equal proportions of Laroflex MP 45 grades and airdrying binders have proven effective.

Two to three coats of thixotropic high-build coatings are needed toobtain the overall thickness of 200–250 µm necessary for effectivecorrosion protection. Depending on the make-up of the system andthe quality of pigments and extenders, the PVC is 30–40 %. Lowerpigmented gloss coats may be used for top coats.

Marine coatings, underwater corrosion protection

Coatings having to withstand sea or river water can be formulatedwith Laroflex MP 45 grades and non-saponifiable hydrophobic plasticizers. Combinations with tar and/or hydrocarbon resins can also beused, some of the Laroflex MP 45 proportion may be replaced by apolyamine-cured epoxy resin. A PVC of 35–40 % is ideal for highbuild coatings. These adhere extremely well to sandblasted steel,commercial shop primers and other unrelated coating systems.

Laroflex MP 45 grades being resistant to alkalis allow formulatingunderwater coatings that give excellent performance in cathodicprotection and on zinc/ethyl silicate primers. Since high-build coatings based on Laroflex MP 45 grades can be sprayed outstandinglywell, only two or three spray coats are needed to achieve perfectcorrosion protection.

11 of 12 Laroflex MP 45 grades

Laroflex MP 45 grades can also be used as binders in antifoulingpaints. Hydrophylic cobinders like Lutonal M 40 approx. 70 % inethanol and/or rosin ensure that the antifouling agent is released ata uniform rate.

Machinery, automotive and container finishes

Suitable coatings can be formulated from Laroflex MP 45 grades androughly equal amounts of air-drying binder.

Coatings on galvanized steel and aluminumAir-drying binders should be avoided in primers and top coats onaluminum or, in particular, galvanized steel. Coatings based onsuch binders could flake or peel off after prolonged exposure tomoisture and fluctuating temperature. Addition of special hardresins, talc and/or micaceous iron oxide allow coats with extremelygood adhesion.

Coatings for mineral substrates

Laroflex MP 45 grades and alkali-resistant plasticizers are used toobtain coatings for mineral substrates. The pigmentation dependson the desired degree of gloss.

Architectural finishes with adequate permeability to water vaporshould have a PVC of 50–60 %.Combinations of Laroflex MP 45 grades, polyamine-cured epoxyresins and tar are used for underwater and underground mineralsubstrates.

The PVC for swimming pool coatings should be at least 50 % inorder to avoid blisters forming from osmosis, even in high-buildcoats.

Since they are resistant to hydrolysis, Laroflex MP 45 grades aresuitable binders for sealing and impregnating primers for stabilizingmineral substrates and reliably ensuring that subsequent coats ofarchitectural finishes adhere well. Depending on the substrate’sactual porosity, the binder concentration in these coatings shouldbe 8–15 %.

Road marking paintsRoad marking paints can be formulated from Laroflex MP 45 gradesalone or combined with air-drying binders. Note, however, that airdrying binders will reduce the life of road markings.Flame-retardant coatings

Özelliklerdeki farkllklar Laroflex MP 45 snflar esas olarak viskoziteleri ve solüsyonlarnn reolojisi açsndan farkllk gösterir. Tabloda verilen viskozite aralklar, 23 ° C’de (73 ° F) toluen içindeki% 20 çözeltilerle ilgilidir. Çözücü ne kadar az polar olursa, viskozitedeki farkllklar o kadar büyük olur.

Laroflex MP 45 ve Laroflex MP 45’in düük viskoziteli çözümleri, alifatik hidrokarbonlarla en kolay seyreltilir, viskozite en az depolama srasnda deiir ve en yüksek parlakl salar.

Laroflex MP 45’in yüksek viskoziteli solüsyonlar, özellikle polar olmayan solventlerde jelleme eilimindedir.

Doru çözücünün seçilmesi Uygun çözücüler aromatik hidrokarbonlar veya bunlarn karmlar ile esterleri ve glikoleeter asetatlardr. Seyreltici olarak alifatik hidrokarbonlar ve / oral alkoller kullanlr.

Ketonlar, genel olarak, vinilklorür polimerler tarafndan eit uçuculua sahip dier çözücülerden daha uzun süre tutulduklarndan daha az uygundur ve bu da daha yava kuruyan kaplamalara neden olur. 12 Laroflex MP 45 kalite

Formülasyondaki dier hammaddeler Laroflex MP 45 snflar ile kolayca uyumluysa ve alifatik hidrokarbonlar veya alkollerde çözünürse seyreltici oran artrlabilir. Örnekler Laropal K 80 gibi sert reçineler, pek çok alkid reçinesi, yüksek aromatik katran dereceleri, yumuak reçineler ve plastikletiricilerdir. Yüksek uçucu solventler ve / veya seyrelticiler, daha hzl kuruyan kaplamalar üretir. Ksilenealon yerine ksilen ve butanol karm içeren kaplamalar daha hzl kurur.

Uzatlm depolamadan sonra, viskozite tekrar artabilir, bu da daha az çözücü güç ve çözücüler ile polimer arasndaki afinite daha belirgindir.

Laroflex MP 45 dereceli inksilenin pigmentlenmemi konsantre çözeltileri, genellikle hazrlandktan sadece aylar sonra ve viskozitede kademeli bir arta uramadan jelleme eilimi gösterebilir.

Ketonlarn ve esterlerin eklenmesi, özellikle balayc konsantrasyonu yüksekse jelleme eilimini azaltr. Çözücü karmna% 10–20 analkol eklenerek, jelleme genellikle tamamen bastrlabilir.
