  Powder coating is a kind of solid powder synthetic resin coating, which is composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not the solvent and water, but the air. It has no solvent pollution, 100% film formation, low energy consumption.

  PCA-302A is an organic functional coupling agent with a grayish-white to white powder, fineness (325 mesh sieving residue)≤10% . Easy to weigh, use, easy to disperse in powder coating system. Mainly used to improve the adhesion of powder coatings, water resistance, and resin has a certain reinforcing effect, can be used for anti-corrosion powder, insulation powder and some cheap resin powder coatings performance.

  This product can react with resin and substrate in both directions, the adhesion of powder coating to glass, metal and polar plastics and the water resistance, boiling resistance, salt spray resistance and pencil hardness of the coating are obviously improved. At the same time this product convection equality surface also has the improvement. 

  Scope of application: pure epoxy, pure polyester, polyester/epoxy blend, polyurethane, acrylic and other common powder coating systems. Anti-corrosion powder coatings, the use of cheap resin powder coatings, insulation powder coatings, higher requirements for water-resistant powder coatings, powder coatings for special substrates. 

  Dosage and usage: 0.2 ~ 1% of the total mass of the formula is suitable, the optimum dosage should be determined by the test, 0.3 ~ 0.5% dosage is common. The product can be mixed and extruded directly with other materials. This product is compatible with resin and other additives, will not affect the surface properties of powder coatings, do not interfere with color matching, there is no bad smell.
