Composition Blend of special fat derivatives and alkylene oxide derivatives with hydrocarbons, con-taining a slight amount of silicone. Ionic character non-ionic DEHYDRAN 1227 may be used for foam suppression during polymerization and also during subsequent processing of the polymer emulsions. It has a good spontaneous and a good long-term defoaming effect. DEHYDRAN 1227, even with regard to the elimination of micro foam, displays an excellent anti-foaming effect when incorporated in emulsion paints based on fine particle size styrene/acrylic copolymers, vinyl acetate/acrylic copolymers, pure acrylics, etc. Long-term evaluations showed no deterioration of the defoaming effect. On account of the test results (good compatibility, no reduction of gloss) DEHYDRAN 1227 is excellently suited for incorporation in emulsion paints containing low pigment quantities (high gloss emulsion paints). Dosage Dosage is 0.2 to 0.7%, calculated on paint formulation. Blend of special fat derivatives and alkylene oxide derivatives with hydrocarbons, con-taining a slight amount of silicone. Defoamer and anti-foaming agent for emulsion paints and polymer emulsions. Non-ionic character. Can be used for foam suppression during polymerization and also during subsequent processing of the polymer emulsions. Provides a good spontaneous and a good long-term defoaming effect. Excellent anti-foaming effect when incorporated in emulsion paints based on fine particle size styrene/acrylic copolymers, vinyl acetate/acrylic copolymers, pure acrylics, etc. Long-term evaluations showed no deterioration of the defoaming effect. Suited for incorporation in emulsion paints containing low pigment quantities (high gloss emulsion paints). Recommended usage level: 0.2 to 0.7%, calculated on paint formulation.
