Details
As a highly inert chemical, Particle Fine Micro is resistant to acids and bases, insoluble in water and any organic solvent, and has good light and weather resistance.
Particle Fine Micro has a Mohs hardness of 3, which makes it less abrasive, and it is white and color-neutral. Therefore, Particle Fine Micro retains the vividness and hue of the system pigments while exhibiting high brightness.
Particle Fine Micro has an average particle size of 0.7 microns, a relative density of 4.4 g/cm3, and a narrow particle size distribution similar to that of titanium dioxide. With special surface treatment, the product is fluffy and has good dispersibility and suspension in coatings and inks, and the surface finish is extremely high. The significant advantage is the low oil absorption and the ability to disperse in any system with only a small amount of base material when used.

Application area
Coatings and paints
Powder coatings: especially suitable for thin coating systems with high gloss requirements, Particle Fine Micro can partially replace other pigments and significantly reduce volatile compounds (VOC).
Automotive paints: Good light retention and excellent mechanical properties, especially suitable for high gloss systems.
Pigment paste: Particle Fine Micro is used as a pigment incremental dispersant to improve the dispersion of pigment powder, which can effectively improve the color vividness and brightness. At the same time, it can reduce the coagulation or flocculation of pigments and make the storage more stable, and replace 10-20% of the total pigments in the formula, the gloss of the formula will not be reduced.
Inks
General ink: Not only improves the gloss of the ink, but also has excellent fluidity.
Line board ink: Cost reduction, smooth and round paint film, good gloss and good whiteness.
Rubber and Plastic
Thermoplastics: Improves the rigidity, hardness and wear resistance of plastic products. particle Fine Micro has high thermal conductivity and rheological properties that shorten the cycle time of injection molding. It also increases the crystallinity of thermoplastic polymers, thus improving the strength (especially impact strength at low temperatures) and stability of products.
Elastomers : Free of rubber toxins, especially suitable as fillers. Has storage stability and anti-aging properties.
Masterbatch ：Improve the efficiency of using color powder in masterbatch and slurry, presenting texture and luxury. Play the role of pigment dispersant in masterbatches.
Others
Films: In stretch and ductile films, it can be used as white pigment and reduce cost by reflecting visible light at the interface between Particle Fine Micro, air two phases.
Children's toys: Particle Fine Micro meets FDA requirements, plus its X-ray opaqueness can be used in children's toy applications. (Easy to find after accidental swallowing)
