Chemical Composition: Polyether - modified polydimethylsiloxane.
Physical and Chemical Properties: Usually a light yellow liquid with no obvious odor. The density is about 1.035 g/cm³ at 20°C. The flash point is greater than 100°C, and the auto - ignition temperature is greater than 200°C. It is completely miscible with water.
Functions and Efficacy: It can moderately reduce the surface tension of the coating system, increase surface smoothness, improve leveling and gloss, prevent the formation of Benard vortices, and at the same time improve substrate wettability and produce anti - tackiness.
Application Fields: Suitable for water - based, solvent - based and solvent - free coating systems, as well as printing inks. It can be used in industrial coatings, automotive coatings, architectural coatings, wood coatings and other fields. In two - component polyurethane systems, it can also be added to isocyanate curing agents.
Usage Method: It can be added at any stage of the production process or added later. For easy addition, it can be diluted with a suitable solvent. The general dosage of the additive is 0.025% - 0.2% of the total formula.
Packaging Specifications: Generally, it is packed in 25kg/barrel.
