Surfboard Laminating Resin
Silmar 249A Plain Clear Laminating Surfboard Resin
Silmar 249A is the primary surfboard laminating resin used by the surfboard manufacturing industry worldwide. Is low viscosity for easy wet out, cures water-white and contains ultra violet inhibitors for a long-lasting surfboard.
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.
