Mold Release Agent

Mold Release Agent is a premium semi-permanent release system designed specifically for composite molding applications. Unlike conventional waxes or PVA (polyvinyl alcohol) films, this advanced formulation chemically bonds to the mold surface, creating a durable, non-stick barrier that provides multiple releases per single application. It eliminates resin transfer, prevents part sticking, and leaves a high-gloss finish on carbon fiber, fiberglass, and Kevlar components. Suitable for hand layup, vacuum bagging, prepreg autoclave curing, and resin infusion processes.

Key Features

• Type: Semi-permanent / solvent-based

• Color: Clear / Transparent

• Compatibility: Epoxy, polyester, vinyl ester, phenolic, polyurethane resins

• Mold Types: Metal (steel, aluminum), composite, fiberglass, coated surfaces

• Multiple Releases: 3 – 10+ releases per application

• Temperature Rating: Up to 400°C (752°F)

• Zero Transfer: Does not transfer to molded part

• No Buildup: Does not accumulate on mold surface

How to Use (Standard Application Process)

Step 1: Clean Mold

• Remove all previous wax, resin, and contaminants

• Use mold cleaner or acetone

• Ensure mold is completely dry

Step 2: Apply Sealer (First Time Only)

• Apply MRA-SEAL to new or stripped molds

• Wipe on, let flash, buff off

• One thin coat only

Step 3: Apply Release Agent

• Shake well before use

• Apply thin, even coat using clean lint-free cloth or spray

• Wipe on – do not pool or puddle

• Allow to dry (10 – 30 minutes at room temperature)

Step 4: Buff (If Required)

• Some grades require light buffing with dry cloth

• Follow product-specific instructions

Step 5: Apply Second Coat

• Repeat step 3 – allow 10 – 15 minutes between coats

• 2 – 3 coats recommended for maximum releases

Step 6: Cure

• Allow final coat to cure for 30 – 60 minutes before molding

• Heat accelerates cure (5 – 10 minutes at 50 – 100°C)

Step 7: Mold Part

• Process your composite layup normally

Step 8: Demold

• Part should release easily

• If sticking, apply additional coat before next part
