Siwell·Rebon® RB-801 additive is a kind of non-ionic organo fluorine surfactant. Minimum dosage of this additive can decrease the surface tension up to 20 mN·m-1 while improve the spreading ability on surface of paints as well as efficiency of surfactant. Besides, RB-801 additive is suitable for most of water, and solvent based systems with its advanced permeation of wetting substrates, pigments dispersing properties, and anti-fouling surfaces.
