Suppressor 1130 is a high-solids emulsion of fatty alcohol and proprietary polymer blends that affords the end-user a versatile foam control agent. The product works well in high surfactant loadings as well as those systems that encounter foam derived from microbial metabolism resulting in persistent, brown-gray foam. Suppressor 1130 should be evaluated in systems where Suppressor 1120 is not sufficient for the foam problem.
