A-72303 AL-1978 POLYURETHANE ELASTOMERS HAVING IMPROVED SAG RESISTANCE (D#75,040-F) Abstract of the Disclosure The use of small amounts of an amine-terminated polyether in the B-component of a two-component polyurethane composition results in the immediate thickening of the A and B-components upon mixing to provide an elastomer precursor with improved sag resistance without substantially affecting the workability of the mixed components or the properties of the cured elastomer, These elastomers are useful as sealants, caulks and surface coatings.
