Conventional fluorescent coatings often face rapid fading and chalking issues. Hongyuan's new Hengyan series overcomes these limitations through composite resin technology and UV-absorption layer optimization, significantly extending outdoor durability for powder and water-based fluorescent coatings. Third-party testing confirms superior performance: **Key Verified Properties** - 1000h xenon-arc accelerated aging: Color difference △E≤0.6 (vs. ≥3.0 for conventional products) - 500h UV aging (UVA-340): Gloss retention ≥85% (vs. ≤60%) - 12-month natural exposure: △E≤1.5 - Salt spray resistance: 500h outdoor / 1000h indoor without corrosion - Thermal cycling resistance (-30℃~80℃): 50 cycles without cracking **Technical Advantages** 1. 60% improved color stability over 5-year service life, addressing premature outdoor failure 2. Water-based formula VOC ≤50g/L (60% below national standard) with 30% faster drying 3. Compatible with steel/concrete substrates; peel strength ≥50N/cm **Field Validation** Shandong logistics park steel roof maintains △E<1.2 after 24 months; automotive parts retain 90% initial nighttime luminance after 2-year outdoor exposure. "Hengyan technology moves fluorescent coating lifespan beyond monthly measurements," states Hongyuan's Technical Director, noting this breakthrough redefines industrial protection standards.
