When proportioned with water, Chemguard Class A foam concentrate changes the water properties, reducing the surface tension and allowing for greater penetration into all Class A fuels. A mixture of foaming and wetting agents, Class A foam also gives the water a foaming ability, so it clings to surfaces without run off.

Chemguard Class A foam is effective in fighting forest fires and many deep-seated fires such as paper, tires, and wooden structures.
