Details
Particle - S is a soft white pigment of pure zinc sulfide composition, made from a highly pure solution of zinc salts and sulfur-containing ions, which is chemically resistant in the pH range of 4-12. It is surface coated and well dispersed.
Zinc sulfide has a refractive index of 2.37, high brightness, and bluish phase. It has low absorption in the near-UV range compared to TiO2, contributing to increased optical brightener compatibility. particle - S is suitable for wear-resistant paint coatings, inks, plastics, paper systems, and glass fiber reinforced plastic systems that require high mechanical properties.
Particle - S performance advantages
▼Blue-phase white pigment
▼Insoluble in water, organic solvents and weak acids and bases
▼Low Mohs hardness (Mohs 3) and low abrasiveness
▼Low absorption of UV-A for use in UV white systems.

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)
