Addition Levels

UNIQ CHEM

Amount of solid additive based on pigment (SOP):

Inorganic pigments: 0.5 – 10%
Organic pigments: 5 – 25%
Base Paints: 0.2 – 1,5%
Color acceptance (post add): 0.2 – 1.5%

The above recommended levels can be used for orientation and needs to be optimized by testing. Best viscosity reduction properties will be obtained when the pH of the final colorant is adjusted to 8 – 8.5
