Cymel crosslinkers
WebCYMEL NF 3030 resin is an effective crosslinking agent for alkyd, polyester and acrylic polymers containing primary hydroxyl functionality. Reactivity with secondary hydroxyl sites is limited under ambient cure. CYMEL NF 3030 resin has a high Tg and should be paired with softer polyols (Tg < 30°C) to avoid film checking or cracking. WebCYMEL® 327 resin is a methylated high imino melamine crosslinker supplied in iso-butanol. It is very reactive and has a tendency towards self-condensation at normal baking temperatures, providing films with very good hardness, gloss, chemical resistance and outdoor durability.

WebCYMEL® 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. WebCYMEL 325 resin is an effective crosslinker for backbone polymer resins containing hydroxyl, carboxyl, and amide functional groups, such as those found on alkyd, polyester or acrylic resins. Although the optimum level of CYMEL 325 resin should be determined experimentally, ratios of 25 to 35% based on resin solids are typically most effectiveb
WebCYMEL 385 resin contains a combination of methoxymethyl, methylol and imino functionalities, making it a very effective crosslinker for backbone polymer resins containing hydroxyl, amide and, to some extent, carboxyl functional groups, such as those found on alkyd, polyester or acrylic resins.
