Water-Based Semi-Permanent Spray Release
Key Features
- Spray application — no buffing required, fast large-area coverage
- Self-leveling fluoropolymer film for uniform release
- Water-based, non-flammable, low-VOC
- 8–12 releases per application for production molds
- Touch-up spray coats possible without full mold strip and re-coat
This water-based semi-permanent spray release agent is formulated for fast, uniform application on large composite molds by spray gun or trigger sprayer. Unlike wipe-on/buff-off semi-permanent releases, this product is applied by spray and dries to a self-leveling fluoropolymer release film without buffing. Particularly suited to production environments where mold size or surface complexity makes wipe application impractical. Compatible with polyester, vinyl ester, and epoxy laminating resins at ambient cure temperatures. Provides 8–12 releases per application cycle on production molds. The water-based carrier is non-flammable, low-VOC, and suitable for facilities with solvent restrictions. Apply 3–4 spray coats on new molds with 5–10 minutes dry time between coats. Touch-up coats can be applied to localized areas without stripping and re-coating the full mold. Suitable for open mold hand layup, spray-up, and vacuum bagging at ambient temperature.

Applications
FAQ
The product can be applied with an HVLP gravity or suction feed spray gun (1.0–1.5mm nozzle, 15–25 psi), a conventional air spray gun, or a simple trigger-type hand pump sprayer for small molds. For production, an HVLP system provides the most consistent film thickness and efficient material use. Thin, overlapping spray passes are preferred over single heavy coats. Clean spray equipment with water after use.
