Originally designed for metal surfaces, RUST GRIP demonstrates excellent adhesion to wood, concrete, fiberglass and many other substrates. RUST GRIP is designed for the encapsulation of and adherence to the tightly bonded surface of lead-based and other toxic paints 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. The polymer literally begins to swell, developing an interlocking network between the pores of the surface and the coating. RUST GRIP is highly recommended as a base coat for SUPER THERM.

No pot life, no catalyzation, no two-part mixing. 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.

PROPERTY CHARACTERISTICS:

RUST GRIP is a one component, ready to use, specially modified urethane coating possessing exceptional remedial properties:

• It prevents the formation of rust on fresh surfaces, and completely stops the growth and spread of existing rust, at the same time, consolidating and strengthening corroded surfaces.
• It can be applied on to rusty metal surfaces after removing ONLY loose particles. There is no need to grit blast down to bright, bare metal.
• It has tremendous penetrative power, thoroughly wetting the surface, then permeating into all the pores in the rust, and beyond, into the base metal. There is acts both chemically and physically to encapsulate the rust, forming an interlocking network which ties it firmly to itself and to the sound metal. During curing, it expands, totally blocking all the pores, thus preventing access to moisture and water vapor. Because RUST GRIP is designed to penetrate into the pores of the metal and/or rusted surface, the initial surface MUST BE COMPLETELY DRY. RUST GRIP is a moisture-curing formulation and will immediately absorb any surface moisture to begin its cure cycle before entering the pores, which will block it from its designed purpose of galvanizing into the surface. On a dry substrate, RUST GRIP will penetrate directly into the depth of the pores, then draw the moisture from the atmosphere to gas itself as a swelling technique to anchor or galvanize itself into the surface.
• In addition it forms a highly durable, very flexible membrane, which is tightly bonded to the substrate (being part of the interlocking network). This membrane is impermeable to water vapor and is highly resistant to mechanical impact and abrasion, to high and low temperatures, and to UV radiation.
• It is also resistant to continuous immersion in almost all the main, aggressive chemical groups, including acids, alkalis, salts, oils, solvents, and other refined petrochemicals.
• It does not disband due to the action of low voltage, underground electrical currents (cathodic disbandment), yet easily conducts higher voltages, thereby avoiding dangerous static electricity buildup.
• It is also capable of being painted on to surfaces which are coated with lead-based and other old-style toxic paints, which it encapsulates, rendering them environmentally harmless. RUST GRIP has the ability to penetrate through the existing coating, it encapsulates and seals it from weathering and protects it from abuse.
• It is cheap and relatively foolproof to use. Unlike other high performance, anti-corrosion protective coatings, it does not involve the mixing of two or more components, and surface preparation is much simpler and cheaper than the sand blast cleaning down to bare metal surface needed by other products. RUST GRIP is made with metallics and will settle on the bottom. Simply stir before use to work the metallics back into the resin.
