CHOOSING MOLD RELEASE

Prepare The Mold Before The Layup

Mold release selection depends on the mold surface, resin system, production process, and desired part finish. Proper surface preparation is critical before applying gelcoat, resin, fiberglass, or composite materials.

Using the right release product helps reduce sticking, protect mold surfaces, improve release consistency, and minimize damage during demolding.

Mold Preparation

Prepare mold surfaces before resin, gelcoat, fiberglass, or composite part production.

Part Release

Help parts separate cleanly from molds while reducing sticking, damage, and surface defects.

Composite Production

Support repeatable fiberglass, resin, gelcoat, and composite manufacturing workflows.
