Protective Coatings

Rubber—Aerosol Can

Rubber coatings withstand salt and acids.

Cannot Be Sold Outside United States—Coatings that cannot be sold outside of the United States do not meet product labeling requirements. VOC (Volatile Organic Compounds) regulations restrict sales to the listed jurisdictions/areas.

Sealant Primers—Although sealant primer is not required for use on all materials, it can be used to prepare any surface to maximize the life of the coating. They cannot be sold outside of the United States due to product regulations.

Topcoats—Apply topcoat to give coated surfaces a glossy finish that resists fading. They cannot be sold outside of the United States due to product regulations.

Condensation-Reducing Protective Coatings


Aerosol Can	Pail

An alternative to jacketing, these coatings prevent condensation from forming on refrigeration, air conditioning lines, and cold-water piping. They are often used on irregularly shaped surfaces, such as fittings, flanges, and valves. All coatings adhere to metal.

Mastics—These coatings adhere to PVC and CPVC in addition to metal.

For Use Outdoors—These coatings create a vapor barrier and protect from conditions outdoors.
