Product Description
Innovative Composite Manufacturing Process
The KPCw1 backsheet employs a unique combination of film lamination and precision coating technologies:
- Weather-resistant layer using high-quality PVDF fluoropolymer film
- Adhesive layer formed by patented fluorinated coating curing technology
- Specially designed PET substrate formulation ensures dimensional stability
- Precision coating process guarantees uniformity across functional layers
Outstanding Environmental Resistance
The PVDF fluoropolymer weather-resistant layer provides multiple protective characteristics:
1. UV protection: Special formulation achieves over 95% UV blocking rate
2. Temperature adaptability: Maintains stable performance from -40°C to 85°C
3. Weather durability: Passes 3000-hour dual 85 (85°C/85% RH) aging test
4. Chemical resistance: Effectively withstands acids, alkalis, solvents, salt spray
5. Mechanical properties: >90% tensile strength retention after damp heat aging
Reliable Bonding System
The fluorinated coating cured adhesive layer has been rigorously verified:
- Peel strength with EVA >60N/cm, ensuring long-term reliability
