CHEMGUARD CLASS A PLUS FOAM
Chemguard Class “A” is a non-corrosive, non-toxic, biodegradable foam concentrate. When mixed with water in the correct proportion, it changes the properties of water. It reduces the surface tension of the water, and produces foam, which allows the water to cling to vertical or horizontal surfaces without run off. This allows the water to absorb more heat and provides greater penetration into Class “A” fuels.

STORAGE
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range 32ºF-120ºF (0ºC - 49ºC), a shelf life of 20-25 years can be expected. When stored in other than the manufacturer's supplied container, check with Chemguard for storage guidelines. If frozen during storage, thawing will render the product completely serviceable.
Note: It is not recommended to pre-mix Class “A” concentrate with water for long-term storage
