TEPPICHE MIT POLYURETHANSCHAUMSTOFF-TEPPICHRÜCKENBESCHICHTUNGEN UNTER VERWENDUNG VON KATALYSATOREN

摘要

Polyurethane foam backed textiles, particularly polyurethane backed carpets can be prepared using a formulation including a dialkyltin sulfide catalyst. Use of the dialkyltin sulfide catalyst allows for a delayed gellation without substantially increasing the time from gellation to cure. The delay in gellation provides for improved handling and backing quality.
