Cymel 27-580 n-Butylated melamine resin Cytec Amino Resins >> Urea based (incl. UF) Coatings >> Waterborne n-Butanol N-BUTYLAteD HIGH IMINO MELAMINE RESINS Butylated high imino melamine resins are similar to those in the high imino methylated melamine series; they are partially methylolated and highly alkylated. They differ from the high imino methylated melamine resins in that they are n-butylated. The butoxy sites impart improved flow and leveling and intercoat adhesion properties. As in the methylated series, their composition contains primarily alkoxy/imino or alkoxy/NH functionality. The advantages are fast cure response at 120-150°C without the need to add a s t rong acid catalyst; fast cure response in waterborne formulations; high film hardness; and low formaldehyde release on cure. In addition to reacting with hydroxyl, carboxyl and amide functionality on polymers, the resins self-condense readily. Therefore, their practical equivalent weight is typically 160-220. They, too, can be stabilized by the addition of an amine and a stabilizing alcohol to the formulation. CYMEL 27-580 High solids, general purpose butylated melamine resin.
