ABSTRACT:
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, andc) 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.
