Overview
Chemlease® PMR-90 EZ is a semi-permanent, solvent-based mold release agent formulated for composite molding operations that need multiple releases between applications. It forms a thin, durable barrier film that withstands high thermal cycling while reducing labor time and cost compared with wax-based release systems.
Suited for open mold and closed mold composite fabrication, Chemlease PMR-90 EZ is used with polyester, vinyl ester, and epoxy resin systems in industries such as marine, wind energy, and transportation composite manufacturing.
Benefits
• HAPs Free*
• High thermal stability
• Easy to apply
• Multiple releases between applications.
• Reduces labor time and cost
Application For Base Coats
1. Mold surface must be thoroughly cleaned to remove all traces of wax, release agents, and other sealers.
2. Surface should be dry and free of contaminants.
3. Saturate clean cotton cloth (not dripping) and wipe on a smooth continuous film. Apply no more than a few square feet at a time.
4. When the film begins to evaporate at the edge, wipe the surface with a second clean dry cotton cloth. Use a circular motion from the outside, working inwards until film is left dry and clear. See Notes.
5. Repeat above procedures until entire mold surface has been covered.
6. Apply 4-5 coats, allowing 15 minutes between each complete coat.
7. Allow 30 minutes for full cure. Proceed with production.
Selection Guide
