High-Gloss Surface Layer with UV Protection
Duratec® Sunshield Clear Topcoat is a specially formulated polyester topcoat that offers you excellent gloss levels and UV stability. #1045 is compatible with epoxy, vinyl ester and polyester resins. It can be applied to epoxy laminates as an in-mold or post-mold coating. It offers a durable surface and has great scratch resistance. Sunshield offers excellent anti-yellowing, making it a perfect coating for epoxy or vinyl ester parts. It offers a fast build for a smooth and pit-free surface, reducing cycle time and labor.
Sunshield is not applied like traditional gel coat. To apply, spray a light mist coat (or dust coat), that must set up for two minutes before further application. The dust coat should be a light fog, not a continuous film. Additional coats of 4-5 mils can be applied, again allowing a minimum of two minutes to out-gas. 12-15 mils will provide a nice finish with UV protection. Up to 22 mils can be applied if the part requires aggressive post sanding.
When applying to laminates post-mold, sand the entire surface with 180 grit sandpaper, proving a mechanical tooth. With epoxy laminates, water washing with clean water and a Scotch-Brite pad is necessary before and after sanding. It is not necessary to water wash polyester or vinyl ester laminates. After sanding, remove all dust and acetone-wipe the surface prior to application. For laminates with severe porosity, the first 2-3 mil pass can be worked with a squeegee to fill the holes. Additional coats can be applied after two minutes and while the surface is tacky. The final spray should be sanded with 400 grit and allowed to cure, for 8 hours prior to the final polishing.
After curing, wet sand with sandpaper grits from 400-1500. Because of the tough, scratch resistant nature of the Duratec Sunshield, regular automotive compounds may not be aggressive enough to remove sanding scratches. For final polishing we recommend our Step 1 & 2 Mold Polish
Requires 2% MEKP hardener.
