| description | Embodiments relate to a polyurethane composition forming a coating, adhesive, sealant, elastomer or reactive injection molding material, the composition comprising an isocyanate component comprising at least one isocyanate-terminated prepolymer, and an isocyanate-reactive component comprising at least one isocyanate-terminated prepolymer, the isocyanate reactive component comprises at least one Lewis acid catalyst polymerized polyether polyol having a weight average molecular weight of from 200 g/mol to 1,000 g/mol, an average primary hydroxyl group content of at least 30%, and an average acetal content of at least 0.05 wt%.
实施方案涉及一种形成涂料、粘合剂、密封剂、弹性体或反应注射成型材料的聚氨酯组合物，该组合物包含异氰酸酯组分和异氰酸酯反应性组分，该异氰酸酯组分包含至少一种异氰酸酯封端的预聚物，该异氰酸酯反应性组分包含至少一种路易斯酸催化剂聚合的聚醚多元醇，该聚醚多元醇具有200g/mol至1,000g/mol的重均分子量、至少30％的平均伯羟基基团含量和至少0.05重量％的平均缩醛含量。 |
