CYMEL® 203 resin

Technical Datasheet | Supplied by allnex
CYMEL® 203 resin by allnex is methylated/n-butylated, high imino melamine crosslinker supplied in n-butanol. It has a slightly higher butoxymethyl content and higher molecular weight compared to CYMEL® 202 resin which provides for better flow and leveling while maintaining fast cure and hydrophobicity. This product is highly reactive and has a high tendency towards self-condensation reactions at rather low baking temperatures providing films with very good hardness, gloss, chemical resistance, and outdoor durability. CYMEL® 203 resin is used in can & container-, general industrial- and automotive coatings. The shelf life of this additive is 720 days.
