Solar Wrap™ UV-Curable Composite Repair System


Solar Wrap™ is a pre-impregnated, bi-directional fiberglass wrap utilizing a UV-curable polyester based resin system. It has been designed to be a very fast return-to-service product which can be applied at any temperature without extended curing times.

This has been achieved by using a curing process that utilizes UV light and is relatively independent of temperature. Solar Wrap™ is provided as a roll of pre-impregnated, woven fiberglass tape in a UV-stable foil pouch and should not be removed outdoors without proper UV cover. Solar Wrap is an excellent and versatile solution for any industry where quick-action repair in adverse conditions is a critical aspect for successful operations.
