Abstract

1486232 Poly(urethane-ureas) MINNESOTA MINING & MFG CO 9 Oct 1974 14878/77 Divided out of 1486231 Heading C3R A sealing composition comprises a solution in a water-miscible solvent of a mixture (M) of water-miscible NCO-terminated prepolymers (P) of a polyol having a plurality of oxyethylene units, these being prepolymers of MW 850- 1000 and of MW 1250-1500, the average MW of the mixture being 1000-1300. In the example, (P) is in the form of a solution containing 2 prepolymers made by reacting TDI separately with PEGs of MW 600 and 1000, dry acetone, non-ionic surfactant, and water containing 2,4,6 - tri(dimethylaminomethyl)- phenol as catalyst. Leakage in a water-barring or holding structure may be prevented or reduced by placing the composition at the site of the leak, whereupon a foamed hydrophilic poly(urethane-urea) seal is formed by reaction in situ with water. Parent Specification is referred to.
