VIALKYD AN 928/65MPAC is a medium reactivity, high hardness. Superior abrasion and impact resistance. Radiant brilliance. Two-pack polyurethane enamels for metal and wood. VIALKYD AN 928 is a branched hydroxyl functional polyester suitable as crosslinker for aliphatic and aromatic polyisocyanates. The components react at ambient temperature and give films with outstanding light fastness and gloss retention. The high reactivity affords crosslinking particularly with Desmodur N, Desmodur L and Desmodur HL grades. VIALKYD AN 928 can be used as sole binder in the formulation of clear and pigmented paints for coachworks and high rise panels affording excellent resistance to abrasion, chemicals and water. The substrates can be wood, metal or plastic.
