Scottech PVA Release Agent Blue (Polyvinyl Alcohol)

Polyvinyl Alcohol Mould Release Agent for Fibreglass and Composite Moulding

Scottech PVA Release Agent Blue 4L is a high quality polyvinyl alcohol (PVA) release coating designed to prevent fibreglass laminates from bonding to mould surfaces during composite manufacturing. This water-based release agent forms a thin, uniform film that acts as a barrier between the mould and the resin system, ensuring clean and easy part release.

The blue tint allows for clear visual coverage during application, helping users achieve consistent film thickness across the mould surface. Once dry, the PVA film creates a reliable separation layer that is compatible with polyester, vinyl ester and epoxy resin systems.

Scottech PVA Release Agent is commonly used in mould making, plug preparation and composite fabrication where surface finish and ease of release are critical. After curing, the film can be washed off with water, making cleanup simple and efficient.

Ideal for use in marine, automotive, fibreglass and industrial composite applications, this release agent helps improve productivity, protect mould surfaces and ensure high quality finished parts.
