Hostatint Bluing Paste
Hostatint Bluing Paste is a binder-free, aqueous multipurpose pigment preparation based on nonionic and / or anionic wetting and dispersing agents and glycols.
Hostatint Bluing Paste has a pourable and pumpable consistency and is suitable for dosing machines.
Because of its good durability,Hostatint Bluing Paste can be used for interior and exterior use after adequate weathering tests.

Notes to the Technical Delivery Specification
The object of this specification is to show, apart from the data given, also the test methods used to obtain the data.
The test methods can be received if desired.
The test and evaluation conditions are briefly described in the notes below.
Varying results can be obtained from this in other test media and/or under other test conditions.
Please take information about characteristic fastness values for the product (lightfastness, etc.) from the pattern cards.
These values are not subjected to routine checks.
Hostatint multipurpose tinting pastes are binder-free pigment preparations, which are compatible with both aqueous and nonaqueous paint systems.
The main fields of application are decorative paints based on aqueous synthetic resin dispersions, medium to long-oil alkyd paints, and white benzine-soluble mixed polymers.
Standardisation is carried out accordingly.
Composition and manufacturing conditions of the individual grades vary and depend on the physical properties of the basic pigments.
Note on 2 – Colour Properties
Testing of the colour properties is carried out in accordance with the test method No. 2/6 “Testing of Hostatint Preparations”, in a white emulsion paint and in a white air-drying paint based on a long-oil alkyd resin both in comparison with the standard quality of the product.
The assessment of relative tinting strength, hue and chroma is carried out colorimetrically.
The relative tinting strength is determined by means of the weighted K/S-sum.
The residual colour difference after strength adjustment is divided – in accordance with the CIELAB-formula (DIN 6174) – into the lightness contribution _L, hue contribution _H and chroma contribution _C.
The tinting strength is given as relative tinting strength compared to the standard.
For the hue assessment, we use _H and for the chroma we use__C, both after adjustment of the tinting strength to the standard.
_L is not assessed because the value approaches zero after tinting strength adjustment.
Note on 3 – Fineness of Grind
The fineness of grind is measured according to test method 1/14.
