Abstract: A two-component adhesive composition is disclosed. The adhesive composition comprises an isocyanate component comprising an isocyanate-terminated prepolymer that is the reaction product of a polyisocyanate and an isocyanate reactive component having an average molecular weight greater than 1,000 that comprises a polyester polyol that is the reaction product of a polyhydric alcohol and a polybasic acid. The NCO content of the isocyanate component is, optionally, between 3 and 9%. The isocyanate reactive component comprises a polyester polyol that accounts for 50 wt % or more of the isocyanate reactive component. The composition further comprises a polyol component comprising polyether polyols having an average molecular weight less than 1,500. The composition still further comprises an adhesion promoter. The average functionality of the adhesive composition is from 2 to 2.4. The adhesive composition provides for improved performance and processability. A method for forming a laminate is also disclosed. A laminate formed by this method is also disclosed.

Abstract: Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer is characterized morphologically by the presence of small discrete morphological domains 0.1 to 3 μm in diameter, and the substantial absence of discrete morphological domains 5 to 30 μm in diameter. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.
Abstract translation: 使用非汞催化剂制备合成聚氨酯弹性体。 弹性体由含有聚醚多元醇，扩链剂，多异氰酸酯和微球体的反应混合物制成。 弹性体的形态学特征是存在直径为0.1至3μm的小的离散形态域，并且基本上不存在直径为5至30μm的离散形态域。 弹性体自身粘附良好，这使得它对于具有复杂几何形状的管道和其他结构的热绝缘非常有用。
