Innovative Application of Chemi Tech Coating in Automotive Leather

Automotive seat leather faces challenges like UV-induced yellowing and oil penetration from sweat or cosmetics. Chemi Tech's hyperbranched acrylic resin and nano-ZnO system deliver dual protection:

UV Resistance: Nano-ZnO blocks UVA (transmission <5%), reducing color shift (ΔE≤1.5 after 240 hours at 80℃).

Oil Repellency: Perfluorohexylethyl acrylate achieves 118° contact angle against oils.

Case: New Energy Vehicle Seat Supplier

A leather manufacturer resolved yellowing on white seats using Chemi Tech's coating:

90% reduction in oil-based stain retention (e.g., sunscreen, grease);

No cracking or hardening after 3-year accelerated aging simulation.

The molecular design ensures moisture permeability (≥5,000g/m²/24h), making it ideal for premium automotive interiors.
