Class A Foams/Wetting Agents- Chemguard’s Class A foam concentrate is a mixture of foaming and wetting agents. When proportioned with water it changes the properties of the water, reducing the surface tension and allowing for greater penetration in all Class A fuel and wildland fires. It also gives the water a foaming ability allowing it to remain and cling to the surfaces without run off. Class A is effective in fighting forest fires and many deepseated fires such as tires, paper, and wooden structures.
