Key Features & Benefits

• Superior high gloss: non-wax, tack-free film produces a bright, mirror-like finish that showcases the detail of your composites.
• High heat resistance: withstands temperatures up to 300°F (150°C), suitable for a wide range of tooling and service environments.
• Easy spray application: formulated for smooth flow through HVLP spray guns, helping achieve fast, repeatable results.
• Flawless finish: reduces surface imperfections and print-through, resulting in a smooth, defect-free appearance.
• Minimal orange peel: delivers a consistently level surface that requires less sanding and polishing.
• No additional wax: self-sufficient clear topcoat cures to a hard, tack-free finish without the need for wax additives.
• Durable & chemical resistant: cross-linked vinyl ester chemistry creates a robust coating that resists chemicals and everyday wear.

Recommended Applications

• Topcoating plugs and patterns: achieve precise, accurate mold replication with a flawless, high-gloss surface.
• Resurfacing composite molds: rejuvenate and extend the life of existing tooling molds with a durable, glossy finish.
• Interior coatings: excellent for open-chug, high-gloss interior composite applications needing superior clarity and durability.

For best results, apply Duratec 1904-045 Clear Vinyl Ester Topcoat in conjunction with Duratec Vinyl Ester Surfacing Primer, and build to at least 18 mils total film thickness for an even and complete cure.
