The Vinyl Hybrid Resin from Perma-Liner Industries is a hybrid vinyl ester with high-rigid polymer backbone, designed with zero styrene and low VOCs. The resin has a standard pot life of more than eight hours and uses an easy initiator with 1 percent cumyl hydroperoxide by weight, making it cheap, easy and effective. It can be steam or hot-water cured at a minimum of 140 degrees F held for 28 minutes, with no post cure. The lower cure temperature means it is gentler on equipment and it is an easier temperature to reach for longer shots. The resin has consistent viscosity and is resistant to sag and draining around the vertical surfaces and reinforcement. 888-336-2568; www.perma-liner.com.
