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.

Features & Benefits
- Effective release agent for epoxies, polyester, and vinyl esters
- Protects ferrous metal molds
- Improves surface appearance
- Produces exceptionally smooth surfaces, made of unsaturated, low-shrink polyester resins that are thermosetting
- No adverse effects on the cure rate
- Decreased labor expenses associated with using external release agents
- Mold cleanliness
- Prevents corrosion in ferrous metal molds while they are being stored
- Decreased risk of costly molds or parts being lost or damaged as a result of incorrect use of external parting agents
Problems Solved
Damage to molds caused by difficult to release materials
Surface defects of molded plastic caused by release from the mold
Insufficient release of epoxy, polyester, or vinyl ester plastics from molds
Applications
Internal mold release for composite manufacturing
