Angus Alcoseal is an all-purpose Alcohol Resistant Film Forming Fluoroprotein Foam, highly effective against a wide range of hydrocarbons and polar solvents.

Alcoseal 3-6% is used at 3% for hydrocarbons and 6% for water soluble (polar solvent) fuels. Alcoseal 3-3% is used at 3% on both hydrocarbon and water-soluble fuels. Alcoseal gives rapid control and post extinction security. Its excellent resistance to water soluble solvents is due to the formation of a cohesive polymeric membrane formed on the fuel surface which protects the foam from polar fuels. It also has exceptional knockdown properties on hydrocarbon fuels even when applied forcefully.
