Chroma-chem® UCD® 5628HS

Chroma-chem® UCD® 5628HS by Chromaflo Technology is an isoindoline yellow pigment dispersion for solvent-based urethane coatings. It exhibits grind, high gloss, transparency (organics), high tinting strength value and no bleed or discoloration. It meets the conditions for pigmented, low volatile organic compound (VOC) polyurethanes to replace low-solids thermoplastic acrylics in applications where exterior durability or chemical resistance of the coatings is required. It is formulated at maximum loadings with a rheological profile that makes them resistant to separation by settling or syneresis. It is designed for use in automotive OEM, automotive refinish, industrial maintenance, marine, and protective coatings. It shows light fastness as well as acid- and alkali resistance. The tint strength of Chroma-chem® UCD® 5628HS is controlled by volume to ± 2% to ensure optimal tinting performance in volumetric dispensing equipment. It is compatible with a wide variety of solvents, resins, polymers, reactive diluents, and additives. The shelf life is 3 years.
