The present invention relates to a process for producing a polyurethane elastomer, a polyurethane elastomer produced by the process, and the use of the polyurethane elastomer in a glass encapsulation/elastic gasket or the like. The process mainly includes adding a hindered amine light stabilizer to the isocyanate-containing component A. Its reaction with the organotin catalyst in the isocyanate reactive component (i.e., component B), which may cause a loss of the catalytic performance of the catalyst, is avoided. The curing speed of the polyurethane elastomer is increased, thereby the production efficiency is improved and costs are reduced. |
