Solar panel aluminum alloy frames stay exposed outdoors for 25+ years. Common universal paint cannot form tight adhesion on smooth aluminum surface, leading to bubbling, peeling and color fading under long-term UV & acid rain erosion, affecting solar module appearance and service life.

FLDC tailor-made coating system for photovoltaic aluminum alloy frames, special metal wetting primer solves poor adhesion defects fundamentally, matched fluorocarbon topcoat for ultra-long weather resistance.

Complete PV frame coating scheme:

1. Specialized Primer for Colorful Aluminum Alloy: Transition adhesion layer for smooth aluminum
2. Acrylic Polyurethane Intermediate Coat: Improve barrier & flexibility
3. Fluorocarbon Topcoat (213 adjustable colors): Long-term anti-chalking finish Core Advantages: ✅ Perfect adhesion on polished aluminum frame, no blister after years of exposure ✅ Resist acid rain, salt mist & intense ultraviolet radiation ✅ 213 customizable colors match PV brand design requirements ✅ Flexible film, adapt aluminum thermal expansion & contraction ✅ Mass production formula for solar panel factories
