Adhesive for solar battery back sheets |
| 摘要 |
An adhesive for solar battery back sheets obtainable by mixing (A) a urethane prepolymer having an isocyanate group at the end with (B) a polyol, wherein the urethane prepolymer (A) is obtainable by a reaction of a hydroxyl group-containing compound with an isocyanate compound, and the hydroxyl group-containing compound comprises a polycaprolactone polyol. Also, cured reaction products of the adhesive. Also, a solar battery back sheet and a solar cell module comprising the adhesive. |
