Abstract
Process for preparing a composition to perform the hydraulic retaining seal, particularly between mechanical parts, characterized in that it consists of an expandable urethane prepolymer and hardenable in the presence of water and atmospheric humidity, which is obtained by reacting in an inert atmosphere, a temperature of 90 to 120º c, preferably at 100-110º c, an isocyanate selected from the group comprising diisocyanates and triisocyanates, preferably diphenylmethane diisocyanate, with a polyether, preferably polypropylene glycol, having a number of oxydyls from 53 to 59, in a proportion of 2- 3 parts of isocyanate per part of polyether.
