Composition: Polyether siloxane copolymer Physical data: Appearance: pale-yellow colored clear liquid. Active matter content:100% Refractive index at 25oC:1.435-1.445. Viscosity at 25 oC:20-50cs. Surface tension (0.1% aq.): 20.0-21.0mN/m Key Features and Typical Benefits: Silicone surfactant for waterborne formulation. It provides powerful reduction in surface tension which leads to excellent substrate wetting and leveling. Application: Improves the wetting and anticratering of water-borne coatings on difficult substrates. Improves the wetting of water later reducible printing inks and release paper of synthetic leather. Dosage (additive as supplied): 0.2-1.0% on total formulation. Package and storage stability: Available in 25 liter pail and 200 liter drums. 24 months in closed containers.
