SF- 239 for the efficient defoamers, with minimal incompatible materials and get the best anti-foaming. Physical and chemical parameters of composition: breaking bubble polysiloxane solution Appearance: colorless to pale yellow liquid Active Ingredients: 0.7% Solvent: two isobutyl ketone Flash point: 47 ℃ characteristic 1, SF- 239 for the efficient defoamers, with minimal incompatible things and get the best anti-foaming; 2, apply to: chlorinated rubber, epoxy, two-component polyurethane, alkyd / melamine, alkyd and self-crosslinking acrylate system. Add the amount of the added amount plus the amount depending on the use of different systems, it is recommended for the total amount of 0.1 to 0.7 percent, test the optimal dosage; to be at a sufficiently high shear for mixing, grinding is recommended before adding the addition.
