WSD-1557 PV Backsheet Coating
- WSD-1557 is a one-component fluorocarbon coating designed for high-performance solar PV transparent backsheet grid applications.
- After passing through the oven, the coating requires no further curing and can meet lamination requirements directly.
- When used together with our WSD-1556 transparent inner coating, it delivers high reflectivity, excellent damp heat aging resistance, and outstanding PID performance, meeting the key performance requirements for transparent grid backsheets.
