WATER-CLEAR ALIPHATIC POLYURETHANE PULTRUSION FORMULATIONS AND PROCESSES
摘要：
Clear polyurethane fiber reinforced composites are produced by a pultrusion process with a polyurethane-forming system that includes: (a) a clear, aliphatic polyisocyanate having a viscosity at 25° C. of no more than 1000 centipoise, (b) a colorless polyol component comprising an amine-initiated polyol having a molecular weight of from about 150 to about 400 and an OH functionality greater than or equal to 3, and (c) a catalyst. These fiber-reinforced composites are characterized by both excellent weathering characteristics and excellent physical properties.
摘要（中）：

透明聚氨酯纤维增强复合材料是通过具有聚氨酯形成体系的拉挤成型方法生产的，其包括：（a）在25℃下粘度不超过1000厘泊的透明脂族多异氰酸酯，（b）无色多元醇组分 包括分子量为约150至约400且OH官能度大于或等于3的胺引发的多元醇，和（c）催化剂。 这些纤维增强复合材料的特征在于优异的耐候性和优异的物理性能。
