Fluorine Copolymer Polycarbonate Coating Abrasion Resistance

The patent applies composite materials by combining fluorine-containing copolymer (providing anti-soiling properties) with polyurethane resin (providing abrasion resistance). This creates a multi-component coating system where each component contributes its superior properties, resolving the contradiction between anti-soiling performance and abrasion resistance that cannot be achieved with single-material coatings.

The patent applies parameter changes by carefully controlling the molecular weight, hydroxyl value, and composition ratios of the polyurethane resin and fluorine-containing copolymer. By adjusting these parameters, the coating achieves optimal balance between durability and texture preservation, allowing the coating to be durable while remaining soft and flexible on soft materials like synthetic leather.

The patent applies local quality by incorporating microparticles specifically for gloss adjustment while maintaining the base coating composition optimized for abrasion resistance. The microparticles are distributed within the durable polyurethane-fluorine copolymer matrix, allowing localized aesthetic modification without compromising the overall structural integrity and abrasion resistance of the coating film.
