White fused alumina F240 for Polyurethane In-Mould-Coatings

White fused alumina F240 works in Polyurethane In-Mould-Coatings to improve the performance. Polyurethane in-mold- coatings are suitable for wear-resistant foam components such as automotive interior accessories, foam shoe sole materials, and the surface of polyurethane foam plastic products. Although the PU slurry is used in injection molds, it adheres to the surface of polyurethane products after injection molding. It plays a role in anti-slip, wear resistance, aging and yellowing prevention, and acid and alkali resistance. Thereby improving the service life of the product and increasing its aesthetic appeal.

Several benefits of adding WFA powder to Polyurethane In-Mould-Coatings :

1. Improve the hardness and wear resistance of the coating.

White fused alumina powder has high hardness, and adding it to the polyurethane coating can improve the hardness, increase the wear resistance, and extend the service life of the coating.

2. Enhance the glossiness and transparency of the coating.

The particles of white corundum powder are small and uniform, playing a filling and enhancing role in the coating, which can make the surface of the coating smoother and more delicate, enhancing its glossiness and transparency.

3. Improve the chemical resistance of the coating.

White corundum F240 mesh has good chemical resistance, and adding it to the polyurethane inner paint can improve the chemical resistance of the coating, making it more corrosion-resistant.

4. Improve the scratch resistance of the coating.

The high hardness of white corundum micro powder can enhance the scratch resistance of the coating, making it less susceptible to surface scratches and damage.

F240 grit white fused aluminum oxide with a particle range of 30-80um. It can blend well with polyurethane materials and exert wear resistance.
