Phos-Chek Class A Foam Solution can be applied by various discharge devices that affect the formation of bubbles.
These different devices produce mixed foam solution varying from a wet or fluid foam suitable for soaking type applications (coal bunkers, peat bogs, dumps, etc.) to a drier shaving cream consistency for long-term foam blanket applications (exposure protection, pretreatment, etc.)
