The Vinyl Hybrid Resin from Perma-Liner Industries is designed with zero styrene, low VOCs and is a hybrid vinyl ester with high-rigid polymer backbone. 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 hot-water or steam cured at a minimum of 140 degrees F held for 28 minutes, with no post cure. The lower cure temperature of 140 degrees F 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.
