Methods And Compounds For Curing Polythiourethane Compositions

US Patent:

Filed:
Nov 8, 2007
Appl. No.:
11/983387
Inventors:
Chad W. Brown - Bartlesville OK, US

International Classification:
C08G 18/18
US Classification:
528 49
Abstract:
The present techniques relate to formulations that include a first part containing active molecules that have an average of at least one thiol group per active molecule and an average of at least one hydroxyl group per active molecule, and a second part containing monomer molecules that have an average of at least two isocyanate groups per monomer molecule. The composition may be mixed with a catalyst composition that contains at least one amine catalyst and at least one metal catalyst. This mixed catalyst composition will substantially cure a mixture of the first part and the second part within less than about 48 hours at ambient temperature.
