Abstract
An applicator delivers from side by side chambers a two-part urethane polymer composition in which the diisocyanate is differentially reactive with two amine components of side B such that an initial, faster reaction with one amine keeps viscosity low while a second, slower reaction with the second amine builds viscosity to a self-supporting paste outside the applicator.
