SF-227 non-silicone defoamers, widely used in industrial coatings, protective coatings, wood and furniture coatings and coil and can coating systems that can be used to eliminate the bubble production, construction and substrate wetting process produces and will not affect the adhesion between the layers. Physical parameters Ingredients: foam destroying polymers, silicone free solution Appearance: colorless to pale yellow liquid Active Ingredients: 45% Density: 0.89g / cm3 (20 ℃) ??Solvent: benzenes flash point: 46 ℃ Features 1, SF-227 has a strong defoaming capability, the system can solve difficult problems defoaming, inhibition stirred into bubbles, to help fine bubbles released from the coating. 2, SF-227 can be used as defoamers and leveling additive. 3, before adding grinding can get the best anti-foaming effect. Application and dosage system suitable for unsaturated polyester, acrylic / vinyl acetate combinations and oil-free polyester. Add the amount depending on the system using different dosage recommended on the total amount of 0.1 to 1.5 percent, test the optimal dosage.
