Overview
ZELEC ® 2-EHP is a blend of acidic and neutralized phosphate esters. The blend of short- and medium-chain esters make ZELEC® a more effective internal release agent in epoxies and vinyl than other phosphate esters. This grade acts as an effective release agent for resin molding operations that use external heat, such as compression, pultrusion, and matched metal die processes.
