Paint, "paint," is just one of them. Refers to a liquid or solid material coated on the surface of the object under certain conditions to form a film for protection, decoration or other special functions (insulation, rust, mildew, heat resistance, etc.). Because of the early coating mostly vegetable oil as the main raw material, it is also called paint. Now synthetic resin has replaced vegetable oil, so called paint. Coating is not liquid, powder coating is coating breed a big kind.
SY - 933 flow ping agent
Sy-933 is a solvent-based and water-based silicone surface additive, suitable for polyurethane paste, paint and ink of synthetic leather, which can greatly reduce the surface tension of the system.
1.Good compatibility
Sy-933 is suitable for most oil-based, water-based and UV systems, and does not affect the transparency of the paint film while adding a large amount.
