||CHROMA-CHEM 844 Colorants are designed specifically for use in high performance, non-aqueous, industrial and maintenance coatings. The various pigments utilized in this colorant line are dispersed in a proprietary acrylic resin vehicle. This vehicle provides excellent wetting and dispersing properties superior to other acrylic resins available.
The solvents used are a variable blend of Propylene Glycol Monomethyl Ether Acetate (PMA) and Naphthol Spirits. They are non-red label and conform to Rule 66 and similar regulations. Each colorant contains a carefully selected and unique blend of vehicle, solvent, pigment and surfactants to yield acceptance in a wide range of nonaqueous coatings applications. The individual CHROMA-CHEM 844 Colorant formulations are designed to minimize the surfactant and additive levels needed to achieve colorant acceptance in a variety of coatings systems.
The pigments in the CHROMA-CHEM were chosen to provide a wide range of hues and good durability, lightfastness and chemical resistance. However, the lightfastness and weathering properties of pigments depend a great deal on the coating in which they are used. Colorants should be tested under accelerated and actual weathering conditions to verify lightfastness and durability and to determine suitability for the desired use.12713-03-0
