Gambaran keseluruhan produk: untuk siapa? masalah apa yang diselesaikan?

Automotive clear coat is an aftermarket repair coating that provides 4S stores, comprehensive auto repair shops, and body and paint centers with the same appearance quality as the original factory paint.The core problem it solves is that after a car is repaired due to a collision/scratch, the color, gloss, and texture of the repaired area must be completely identical to the original paint (no color difference) – meaning that non-automotive paint professionals simply cannot distinguish the repair marks. Kexin Automotive Clear Coat System precisely matches the original manufacturer's color code (OEM Color Code), ΔE<1.0（CIELABColor Difference公式，人眼无法分辨），DOI>85 (meets automotive Class A surface standards), 60°C x 30 min rapid curing – helps repair shops shorten delivery time from 3 days to 1 day.

Sistem produk:Automotive clear coat is a complete coating system—not a single product. It includes: ① Epoxy primer (provides adhesion + rust prevention, suitable for multiple substrates such as carbon steel, galvanized sheet, aluminum alloy, and plastic) → ② PU intermediate primer/surfacer (fills sanding marks and micro-pinholes left after putty sanding, providing a smooth base) → ③ Color coat/topcoat (available in three series: solid color, metallic flash, and pearl, offering color and decorative effects) → ④ 2K high-solid clear coat (provides protective overcoating + mirror-like gloss with DOI > 90, using aliphatic hardener to prevent yellowing). The adhesion between each layer is Grade 0 (cross-cut test per ISO 2409). The 2K system forms a three-dimensional network structure through the cross-linking reaction between isocyanate and hydroxyl groups—the cured coating is resistant to gasoline, engine oil, brake fluid, and cleaning agents (no abnormalities after 24 hours of exposure to each).

Latar belakang industri:According to statistics from the China Association of Automobile Manufacturers, China's car ownership reached 340 million vehicles in 2024—resulting in over 200 million bodywork repairs annually due to traffic accidents and scratches. The automotive clear coat market is approximately 12 billion yuan per year. Traditional solvent-based repair paints have VOC levels exceeding 500g/L—environmental restrictions have been implemented in many regions (Beijing, Shanghai, and Shenzhen have banned the use of solvent-based repair paints in 4S dealerships). Kexin water-based automotive clear coat series has VOC...<100g/L——Meets最严格的地方Eco-Friendlystandard。
