Sunrez UV Vinyl Ester Prepreg Fabric - Non Hazardous
Sunrez UV cured Prepregs are chopped strand mat and Combi 900 fabrics combined with 7355 UV Vinyl Ester resin. The prepreg is sandwiched between a UV blocking film on the back side, a clear film on top, and further encapsulated but a secondary UV blocking film adheres to the top clear film to provide complete UV protection of each prepreg. This prepreg does not require special storage temps and can easily be applied to anywhere the repair is needed. Available in 12"x 12" sheets and 300mm x 750mm sheets.
Features:
- Single component system - No mixing!
- Very long working time - this will not cure without UV
- Rapid cure under UV - patches are ready to paint in less than 10 minutes
- Cure independent of temperature - suitable for applications from -20F to 120F
What Is Sunrez UV Vinyl Ester Prepreg Fabric?
Sunrez UV Vinyl Ester Prepreg is a ready-to-use repair prepreg: fiberglass fabric already combined with 7355 UV Vinyl Ester resin, available in chopped strand mat and Combi 900 fabric styles. Because the resin is already in the fabric, there is no mixing or measuring required. The resin cures on demand under UV light, so the material has unlimited working time until it is exposed to sunlight or a UV lamp.
Why Choose Sunrez UV Vinyl Ester Prepreg Fabric?
The on-demand UV cure is the defining advantage: Sunrez UV Vinyl Ester Prepreg gives unlimited working time in the absence of UV light, then cures fast when exposed. That combination makes it well suited to field repairs where controlled cure timing matters. The vinyl ester resin chemistry brings good corrosion resistance and mechanical properties. No mixing, no catalyst measurement, and no waiting on a gel time.
What Are the Best Applications for Sunrez UV Vinyl Ester Prepreg Fabric?
Sunrez UV Vinyl Ester Prepreg is best used for structural and cosmetic composite repairs in the field, particularly where fast on-demand cure and corrosion resistance are important. Both chopped strand mat and Combi 900 fabric styles are available to suit different repair geometries and strength requirements.
How Should Sunrez UV Vinyl Ester Prepreg Fabric Be Used for Best Results?
Apply Sunrez UV Vinyl Ester Prepreg to a clean, prepared surface away from direct UV light. Use Sunrez 1022 UV Primer as the bond coat for best adhesion to the substrate. Once the material is in place, expose it to sunlight or a UV lamp to initiate the cure. Use UV Blocking Film to control working time, and PET film over the surface for a tack-free cure.
