WEATHERABLE BACKSHEET FOR SOLAR CELL MODULE

摘要

Provided is a weatherable backsheet for solar cell modules which comprises a cured coating film and a water-impermeable sheet, the cured coating film having improved secondary adhesion to the water-impermeable sheet. The backsheet is produced using a coating composition having a prolonged pot life, and film blocking during the production can be avoided. The weatherable backsheet for solar cell modules comprises a water-impermeable sheet and a cured coating film layer formed on at least one surface thereof, the coating film layer comprising a cured object of a coating composition which comprises a hydroxylated fluoropolymer and silicon oxide particles having an average primary-particle diameter of 0.1-30 µm.
