Weather-resistant adhesive composition |
摘要 |
The present invention is to provide a weather-resistant adhesive which achieves adhesive property, moist heat resistance and weather resistance in a practical level by means of aging at low temperature and for short time. There is provided a weather-resistant adhesive composition, characterized in containing (A) a polyester polyol having an acid value of 30 to 150 equivalents/106 g and (B) a polyisocyanate compound comprising an aliphatic polyisocyanate compound and/or an alicyclic polyisocyanate compound. Also, there is provided a layered product, characterized in being prepared by laminating films using said composition. |

1. A weather-resistant adhesive composition, containing (A) a polyester polyol having an acid value of 30 to 150 equivalents/106 g and (B) a polyisocyanate compound comprising an aliphatic polyisocyanate compound and/or an alicyclic polyisocyanate compounds, wherein the polyester polyol (A) contains 60 molar % or more of isophthalic acid and/or orthophthalic acid as a whole to the total acid components constituting the polyester polyol, and wherein a glass transition temperature of the polyester polyol (A) is −20 to 20° C. and a number-average molecular weight of the polyester polyol (A) is 5,000 to 40,000. |
