CYMEL-203
CYMEL® 203 resin is a 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 which provides for better flow and leveling while maintaining fast cure and hydrophobicity. CYMEL® 203 resin 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.
