Abstract
A composition is provided adapted for a dual chamber (12, 14) applicator 10 having a common mixing zone 42, the composition comprising a low viscosity side A liquid mixture of a hydroxyl functional moiety component and at least two isocyanate components thixatropically reactive with amines, and a side B of at least two amines differentially reactive with said isocyanates in side A for a reaction first to a relatively low viscosity mass and thereafter to a relatively high viscosity mass as a function of time in passing through and then out of the applicator mixing zone 42.
