    摘要: Replacement of one-third to two-thirds of the short chain diols in a polyisocyanate/polymeric polyol/short chain diol molding composition with a hydroxyalkyl-melamine provides shaped articles of increased high temperature stiffness and reduced heat sag. The hydroxyalkylmelamine is strongly catalytic for the isocyanatepolyol reaction.

    摘要: An adhesive, sealant or coating composition that includes: a) 20 to 80% by weight, based on the weight of a), b), and c) of a polyether urethane containing two or more reactive silane groups and one or more polyether segments, b) 20 to 80% by weight, based on the weight of a), b), and c) of a polyether urethane containing one reactive silane group and one or more polyether segments, and c) 1 to 60% by weight, based on the weight of a), b), and c) of a pigment having a BET surface area of from 15 to 100 m2/g and an oil absorption of from 40 to 110 cc/100 g; where the sum of a), b), and c) does not exceed 100% by weight. The composition can be used to bond and/or coat substrates.
