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