Phenolic Sealer

From a technical perspective, phenolic sealers are available in phenolic-modified epoxy sealers, pure phenolic resin sealers, and high-temperature resistant grades, depending on application demands. Typical applications include steel structures, storage tanks, chemical processing equipment, industrial floors, marine decks, wood panels, and metal substrates exposed to solvents, fuels, and moisture. The main ingredients generally include phenolic resins, epoxy or synthetic binders, solvents, curing agents, and performance-enhancing additives. Key advantages of phenolic sealers include excellent chemical resistance, strong adhesion to metal and concrete, good thermal stability, low permeability, and compatibility with epoxy, polyurethane, and phenolic topcoats.
