RUSTGRIP ® is a one-part polyurethane coating that combines with atmospheric moisture to cure. Upon curing, RUSTGRIP ® provides a protective coating of superior adhesion, flexibility and abrasion / impact resistance. It is resistant to chemical solvents and acid splash. Originally designed for metal surfaces, RUSTGRIP ® demonstrates excellent adhesion to wood, concrete, fiberglass and many other substrates.
RUSTGRIP ® is designed for the encapsulation of and adherence to tightly bonded surfaces of lead based and other toxic paints and materials as well as rusted surfaces. This unique ability is accomplished by the curing mechanism of the base polymer.
The coating ( having a low initial viscosity ) wets the rusty surface, then penetrates to the foundation of the rust’s origin where curing begins. RUSTGRIP ® actually becomes part of the substrate unlike a surface coating which just bonds on top. The polymer literally begins to swell, developing an interlocking network between the pores of the surface and the coating. RUSTGRIP is highly recommended as a primer coat for SUPERTHERM ®. No pot life, no catalyzation, no two-part mixing.
RUSTGRIP ® is not a sacrificial rust inhibitor such as a zinc enriched primer that will wear out over time but in fact a permanent rust proofing which is why it is a certified ( ASTM E1795 ) Biohazard Encapsulator. RUSTGRIP ® has also passed 15,000 hours of salt spray testing which far exceeds the marine specifications and consequently has achieved DNV certification. Can substitute for zinc-rich primer requiring no white sandblasting. Can be applied over rusted surfaces after loose / flaking material is removed. High humidity quickens dry / cure cycle.
Using RUSTGRIP ® is approximately 77% Less Expensive than a traditional 3-Part System!
