Bismuth Catalysts and their performance in Polyurethane Applications
Organotin compounds are well known as catalysts for the acceleration of the Urethane reaction. Especially, Dibutyltindilaurate (DBTL) plays an important role in industry, and is used in numerous applications.The main reason for this is the high catalytical activity of DBTL, which increases the reaction speed even at very low dosage levels. Additionally the compatibility of DBTL with a great...
Presented at: THE WATERBORNE SYMPOSIUM - Advances in Sustainable Coatings Technology January 30 – February 1, 2008, New Orleans, LA, USA (Sponsored by The University of Southern Mississippi, Department of Polymer Science) Abstract A new class of versatile aliphatic polycarbonate macrodiols has been developed by Perstorp. In this paper these polycarbonates are evaluated...
The route to low-abrasion PU elastomers
A new generation of amine-crosslinkable prepolymers is both easy to process and free from toluene diisocyanate (TDI). This can be used to produce polyurethane hot cast elastomers that are noted particularly for their excellent tear propagation resistance and hydrolysis resistance. Current tests have shown that elastomers based on prepolymers from the Baytec® MAX series of products also...
