NX 795 coalescing agent for latex products
Promotes uniform film formation with optimal properties
Universal in all latex systems
Easy to incorporate
Reduces minimum film-formation temperature
Non-VOC and non-HAP provides cleaner air and safer handling
Superior properties
NX 795 is an effective coalescing agent for latex formulations
such as acrylic dispersions, styrene acrylics and vinyl acetate
co-polymer dispersions. This ester alcohol effectively reduces the
minimum film-formation temperature (MFFT), and provides
further benefits in end-product properties including higher
coating gloss, increased film integrity, reduced film porosity
and less cracking.
Universal
Incorporation of NX 795 results in optimal paint performance
even at lower drying temperatures. NX 795 also facilitates the
use of hard latexes at low temperatures, broadening the range
of practical application temperatures in many latex paint
formulations. NX 795 does not dissolve in water, but is readily
absorbed by latex particles making it an effective film-forming
additive even when applying paint on porous substrates and in
moist environments.

Reducing MFFT
NX 795 is an extremely effective additive for decreasing
the minimum film-formation temperature of latex paints.
A substantial reduction in MFFT can be achieved by adding
small amounts of NX 795 to paint. In most cases a suitable
addition level is 5-10%, based on latex solids. The harder the
polymer, the higher the level needed; possibly up to 20% for
polymer solids.
Ensuring the optimal performance of a latex paint requires
just the right amount of coalescing aid. The MFFT of the latex
dispersions and the efficiency of the coalescing aid to decrease
the MFFT are important in determining the correct amount
of NX 795 to add. One should also take into account the
conditions under which the paint is applied. The MFFT for
indoor applications is generally 0°C to 5°C, but the MFFT
for outdoor applications is often considerably lower.
Improving hardness
NX 795 contributes to good hardness development in paint
film at normal levels of addition. Excessive amounts of coalescent should be avoided as this will lead to retarded hardness
development.

Effective additives for ideal properties
Proven pH & viscosity stability
Essential requirements for any high-quality paint product are pH and viscosity stability. Hydrolysis of the coalescing agent would reduce paint performance but an experiment demonstrates the stability of NX 795. NX 795 is a hydrolytically
stable coalescing aid that is hardly affected by the alkaline nature of typical latex formulations. Extremely high pH values(>10) are however not recommended.
In a stable paint, the paint viscosity is expected to remain virtually constant over the time of storage. In this test, paint samples were stored at 23°C and 50°C. Viscosity was measured at specified intervals by a Brookfield low shear viscometer.
Negligible change of the paint viscosity is a good indication of the hydrolytic resistance of NX 795 coalescing agent.
Safer performance with environmentally friendly paint
Thanks to its properties, only very low concentrations of NX 795 are emitted during the use of paints containing NX 795 as the coalescing agent. NX 795 is not classified as VOC material in
Europe (1999/13/EC and 2004/42/CE) and not as HAP in the U.S. (Clean Air Act 1990). NX 795 is not classified as a VOC per China State Environmental Protection Agency. The high boiling point, >250°C, and low vapor pressure, <0.01 kPa at 20°C, indicate low volatility of the NX 795 coalescing aid.
Ensuring Optimal Results
NX 795 can be easily incorporated into a paint formulation
during the last stages of paint manufacture. Once the coalescent is added it is recommended to allow the paint to stabilize
overnight prior to application or testing

GENERAL DESCRIPTION of NX 795
Due to low vapor pressure, it meets VOC limitations according to many standards. Burning and poisoning are low, and there is high fragmentation in the environment. A large proportion of water-based paints (Latex Paints) require coalescence additives to form a film at room temperature. In others, these contributions play a role in the film formation, ensuring film integrity and in extreme conditions outside room temperature.
NX 795 is the highest performance additive that can be used for these purposes even at low concentrations. NX 795 is a very odorous liquid, with little effect on the odor of paint in many stages of drying. It not only increases the scrubbing resistance of normal disperse dyes but also increases the scrubbing resistance of over-charged disperse dyes.
NX 795TM ester alcohol is the premier coalescent for latex paints. It performs well in all types of latex paints, in a variety of weather conditions, and over substrates with different levels of porosity.NX 795TM ester alcohol provides the highest level of film integrity at low levels of coalescent, enhancing the performance properties of the paint including low temperature coalescence, touch-up, scrub resistance, washability, color development, thermal flexibility, and resistance to mudcracking. Eastman NX 795TM; ester alcohol also enhances thickening efficiency when used with associative thickeners.
NX 795TM ester alcohol also works well in a variety of other applications. It is an ideal choice as a retarder solvent for use in coil coatings and high-bake enamels. Its unique balance of properties also makes it useful for a variety of chemical specialty applications such as ore flotation / frothing, oil-drilling muds, wood preservative carriers, and floor polishes.NX 795 can also be used as a solvent in nail polish.

NX 795
Agent de coalescence NX 795 pour produits en latex
Favorise la formation d’un film uniforme avec des propriétés optimales
Universel dans tous les systèmes en latex
Facile à intégrer
Réduit la température minimale de formation de film
Sans COV et sans HAP pour un air plus pur et une manipulation plus sûre
Propriétés supérieures
NX 795 est un agent coalescent efficace pour les formulations de latex
comme les dispersions acryliques, les acryliques styréniques et l’acétate de vinyle
dispersions de copolymères. Cet alcool ester réduit efficacement la
température minimale de formation de film (MFFT), et fournit
avantages supplémentaires dans les propriétés du produit final,
brillant du revêtement, intégrité accrue du film, porosité du film réduite
et moins de fissures.
Universel
L’incorporation de NX 795 donne des performances de peinture optimales
même à des températures de séchage plus basses. NX 795 facilite également la
utilisation de latex durs à basse température, élargissant la gamme
des températures d’application pratiques dans de nombreuses peintures au latex
Formulations. Le NX 795 ne se dissout pas dans l’eau, mais est facilement
absorbé par les particules de latex, ce qui en fait un filmogène efficace
additif même lors de l’application de peinture sur des substrats poreux et
environnements humides.

Réduire le MFFT
Le NX 795 est un additif extrêmement efficace pour diminuer
la température minimale de formation de film des peintures au latex.
Une réduction substantielle du MFFT peut être obtenue en ajoutant
de petites quantités de NX 795 à peindre. Dans la plupart des cas, un
le niveau d’addition est de 5 à 10%, basé sur les solides en latex. Plus le
polymère, plus le niveau requis est élevé; jusqu’à 20% pour
solides polymères.
Assurer les performances optimales d’une peinture au latex nécessite
juste la bonne quantité d’aide coalescente. Le MFFT du latex
les dispersions et l’efficacité de l’aide à la coalescence pour diminuer
les MFFT sont importants pour déterminer le montant correct
de NX 795 à ajouter. Il faut également tenir compte des
conditions dans lesquelles la peinture est appliquée. Le MFFT pour
les applications intérieures sont généralement de 0 ° C à 5 ° C, mais le MFFT
pour les applications extérieures est souvent considérablement plus faible.
Amélioration de la dureté
Le NX 795 contribue au bon développement de la dureté de la peinture
film à des niveaux d’addition normaux. Des quantités excessives de coalescence doivent être évitées car cela entraînerait un retard de dureté
développement.

Additifs efficaces pour des propriétés idéales
Stabilité éprouvée du pH et de la viscosité
Les exigences essentielles pour tout produit de peinture de haute qualité sont la stabilité du pH et de la viscosité. L’hydrolyse de l’agent coalescent réduirait les performances de la peinture mais une expérience démontre la stabilité du NX 795. Le NX 795 est un
aide à la coalescence stable qui n’est guère affectée par la nature alcaline des formulations de latex typiques. Des pH extrêmement élevés (> 10) ne sont cependant pas recommandés.
Dans une peinture stable, la viscosité de la peinture devrait rester pratiquement constante pendant la durée de stockage. Dans ce test, les échantillons de peinture ont été stockés à 23 ° C et 50 ° C. La viscosité a été mesurée à des intervalles spécifiés par un viscosimètre Brookfield à faible cisaillement.
Un changement négligeable de la viscosité de la peinture est une bonne indication de la résistance hydrolytique de l’agent coalescent NX 795.
Des performances plus sûres avec une peinture écologique
Grâce à ses propriétés, seules de très faibles concentrations de NX 795 sont émises lors de l’utilisation de peintures contenant du NX 795 comme agent coalescent. Le NX 795 n’est pas classé comme matériau COV dans
Europe (1999/13 / CE et 2004/42 / CE) et non comme HAP aux États-Unis (Clean Air Act 1990). Le NX 795 n’est pas classé comme COV par l’Agence chinoise de protection de l’environnement. Le point d’ébullition élevé,> 250 ° C, et la basse pression de vapeur, <0,01 kPa à 20 ° C, indiquent une faible volatilité de l’aide de coalescence NX 795.
Assurer des résultats optimaux
NX 795 peut être facilement incorporé dans une formulation de peinture
pendant les dernières étapes de la fabrication de peinture ré. Une fois le coalescent ajouté, il est recommandé de laisser la peinture se stabiliser
pendant la nuit avant l’application ou le test
