Adhesive for solar cell backsheet, polyol composition for solar cell backsheet adhesive, solar cell backsheet, and solar cell module

摘要

Adhesive for solar battery back sheet that has excellent curing speed and can exhibit excellent adhesive performance with short-term aging, polyol composition used in the adhesive, solar battery back sheet using the adhesive, and the A solar cell module using a sheet is provided. One or more hydroxyl group-containing resins (A) selected from polyester polyurethane polyol (A1), polyester polyol (A2), hydroxyl group-containing (meth) acrylic resin (A3) and hydroxyl group-containing hydroxyl group-containing fluororesin (A4), polyisocyanate ( B) and the cyclic amide compound (C) are essential components.
