The Syntho-Shield™ system is comprised of two components, the Syntho-Glass® for mechanical and corrosion abilities as well as a Petrolatum Tape undercoating for long term corrosion protection.

The Petrolatum Tape under coating is composed of a non-woven synthetic fabric carrier, fully impregnated with a neutral compound based on saturated petrolatum and inert siliceous fillers. The tapes are designed to provide long term corrosion protection to pipes, flanges, valves, and related surfaces. This unique protective coating system has been designed as an effective solution to corrosion, insulation, and waterproofing problems.

Syntho-Glass®, a fiberglass cloth impregnated with a water activated resin, is used as a protective outer wrap. Syntho-Shield™ is an innovative system that offers exceptional mechanical and impact strength for under water, under ground and above ground corrosion protection coating applications. For above ground applications requiring UV protection, Syntho-Glass® UV is recommended.
