UV Cure - Surfboard Laminating Resin

$85.80 USD

Silmar 249A Clear Resin + UV Cure

UV Cure Resin Laminating Resin is designed to cure once exposed to sunlight, MEKP catalyst can also be added to assist cure under laminates that may block UV rays, such as logos or fin boxes.

This resin is air-inhibited which means it will cure to a tacky finish not requiring sanding between layers, because the layers adhere to each other better and should not be used as a final coat unless measures are taken to seal out the air during the curing process. This resin is designed to  be use for initial coats or for multiple layers with fiberglass cloth or mat. "wax additive" is needed to make a fully cured sand-able finish coat.
