SF-216 non-silicone defoamer for solvent and non-solvent-based coatings, inks, and thermosetting resin system that can be used to eliminate the bubble production, construction and substrate wetting generated in the process, and will not affect interlayer adhesion. Physical parameters Ingredients: foam destroying polymers, silicone free solution Appearance: colorless to pale yellow liquid Active Ingredients: 20% Density: 0.82g / cm3 (20 ℃) ??Solvent: petroleum solvent / hydroxy-butyl acetate / ethylene glycol ether 71/8/1 flash point: 34 ℃ characteristic 1, SF-216 has a strong anti-foaming ability, can solve the problem of anti-foaming system difficult to suppress stirring into bubbles, tiny bubbles help from the paint are released. 2, SF-216 can solve the matte powder and stir bubble zinc helps porous substrate degassing construction time. 3, SF-216 does not affect inter-layer adhesion, especially for defoaming primer. Application system and the amount recommended for the two-component PU system, amino paint system, nitro dipping system, amino acid curing systems, coil coatings. Add the amount depending on the system using different dosage recommended on the total amount of 0.05 to 0.5 percent, test the optimal dosage.
