Cymel 1133 Resin is a highly methylated- n-butylated melamine crosslinker with a high degree of alkylation. It has a higher butoxymethyl content and higher monomer content compared to CYMEL 1130 resin. Its hydrophobic nature combined with very good film appearance properties makes CYMEL 1133 resin suitable for automotive topcoat applications and general metal finishes requiring improved durability and resistance properties.
