Heat Stability
Determination of heat stability is determination of temperature. In °C at which the discoloration corresponds to the color difference. dE - 3.0 units. For Printing Inks - tested in long oil alkyde resin system for 30 min.
It is however advisable for a user to carry out heat stability tests in intended application under given set of processing conditions.
Overspray Fastness
The bleeding of colored paint film into subsequent paint film caused by pigments that are dissolved to some extent by the solvents and binders of the coating paints.
This phenomena is distinctly pronounced in overpainting with white pigmented paints over some azo pigments particularly Reds.
The degree of bleeding is markedly influenced by assessing extent of bleeding of a respective pigments full shade. Alkyd melamine base coat into a TiO2 containing stoving white enamel applied on top of flashed oil/dried base coat in comparison to standard under indenticial test conditions.
The extent of bleeding is assessed as per greyscale for bleeding on 1 to 5 scale where 1 - poor, 5 - excellent.
Fastness to Solvents and Chemicals
The test is carried out by placing 0.5gms of pigment in a folded paper, sealed at the top and suspended in 20 cc of solvent in a stopper test tube at the room temperature for 24 hours. The staining is noted and expressed in 1 to 5 scales. 5 = excellent, 4 = very good, 3 = good, 2 = fair, 1 = poor.
Solvent mixture generally contains 30% ethyl acetate, 10% acetone, 20% xylene, 30% ethanol, 10% 1 methoxypropanol. The staining of test solvent is assessed visually in comparison to that of the product standard for controlling quality and against absolute solvents for reporting solvent fastness of individual pigment in accordance with grayscale for assessing the extent of bleeding. (DIN 54002).
