Technical Datasheet | Supplied by allnex
CYMEL® 1158 resin by allnex is n-butylated melamine-formaldehyde cross-linking agent with a medium to high degree of alkylation, a low to medium methylol content and a medium to high amino functionality. It is especially designed for medium solids systems, providing fast cure response, low blistering tendency and low formaldehyde release during cure. It possesses a high tendency to self-condense resulting in films with high film hardness that can be adjusted based on loading. CYMEL® 1158 resin improves substrate wetting, flow and leveling, and humidity and salt spray resistance. Recommended for automotive topcoats and general industrial finishes. The shelf life of this additive is 720 days.
