What type of white corundum powder is used for plastic coating
Particle size range of white corundum powder commonly used in plastic coating:
Fine surface treatment/increase slight wear resistance/matting agent:
Model range: F500-1000 (corresponding to the approximate range of particle size: 20µm – 10µm) or finer,
such as F1500 F2000 (7µm 5um, 3.5µm).
Features: The particles are fine, and adding them to the coating can provide a fine matte texture, a slight matte effect, and can improve the surface hardness and wear resistance, while having a relatively small effect on the gloss of the coating. Suitable for occasions where a certain surface smoothness needs to be maintained but functionality needs to be increased.
Medium wear resistance/adhesion promotion/texture effect:
Model range: F320 – F360 (corresponding to the approximate range of particle size: 40µm – 28µm)
: Features Slightly larger particles can more effectively increase the wear resistance of the coating,
provide a more obvious frosted or textured effect (depending on the amount added and the degree of dispersion), and also improve the coating force between the coating and the substrate or other coatings (by increasing the roughness of the coating). This is a more commonly used range.
High wear resistance/rough texture/heavy load application:
Model range: F230-280 (corresponding to the approximate range of particle size: 63μm – 50μm)
Features: The larger particles can significantly improve the wear resistance and scratch resistance of the coating, forming a very obvious rough texture or wear-resistant surface. Suitable for the surface of plastic parts that need to withstand heavier fatigue or require strong wear resistance.
