Mica Powder CJ-A4 for Paint, Coatings, and Rubber Industries
Product Overview
Lituo Mica Powder CJ-A4 is a next-generation muscovite mica engineered to redefine performance standards in paints, coatings, and rubber formulations. With ultrafine 2000 mesh particle size (D97: 5–8 µm) and ≥99% crystalline purity, this lamellar filler delivers unparalleled barrier properties, UV resistance, and mechanical reinforcement for demanding industrial applications. Packaged in 25 kg anti-moisture laminated bags, CJ-A4 complies with REACH, RoHS 3.0, and ISO 9001:2015 standards, making it ideal for automotive coatings, marine paints, industrial rubber seals, and corrosion-resistant linings.
Designed to outperform traditional fillers like silica, talc, and kaolin, CJ-A4 enhances product lifespan while reducing VOC emissions, cracking risks, and production costs in spray-applied coatings, extrusion-molded rubber, and high-temperature curing systems.
