SERDAS DF 7540 is a silicone free liquid defoamer for use in waterborne systems. SERDAS DF 7540 has outstanding emulsifying properties in water. Its chemical description is a EO/PO ester of tall oil fatty acid.
ADDITOL VXW 4973 is an easily emulsifiable defoamer with very good incorporating ability. It is suited for defoaming of coarse-disperse to fine-disperse (plastic) dispersions on the basis of PVAC, PVC, acrylates and their copolymerisates. Also low-viscous products may be defoamed with ADDITOL VXW 4973.
ADDITOL XW 376 can be used in most waterborne emulsion paints and adhesives, and in synthetic resin-bound renderings. Good storage stability even at elevated temperatures. ADDITOL XW 376 is effective in large to fine particle size dispersions based on polyvinyl acetate, PVC, acrylates and their copolymers as well as alkyd resin emulsions. It is easily emulsified and also incorporated in low viscosity systems. ADDITOL XW 376 is equally useful in deaeration during pigment grinding and in the filling process. It is shear stable and alkali resistant up to pH = 13.
