Syntho-Shield® by Neptune Research Inc (NRI)


Corrosion protection tape coating system

The Syntho-Shield™ system is comprised of three components; a Petrolatum primer/tape system undercoating for long term corrosion protection, Syntho-Glass® XT for mechanical protection, and Syntho-Glass® SPF as a final mechanical and UV protection barrier. 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 XT, a fiberglass cloth impregnated with a water activated resin, is used as a protective outer wrap. Syntho Glass SPF is a UV-stable fiberglass cloth impregnated with a unique water-activated resin as a final, outer wrapping for additional mechanical and UV protec-tion. Syntho-Shield is an innovative system that offers exceptional mechanical and impact strength for under water, underground and above ground corrosion protection coating applications.
