POLYURETHANE-BASED SEALANT FOR INSULATED GLASS UNITS

摘要

Insulated glass units are sealed with polyurethane made using a natural oil-based polyol (NOBP). In one embodiment the NOBP is made using a monol-rich monomer containing high levels of mono-hydroxy functional fatty acid methyl esters. Insulated glass sealants based on these compounds provide enhanced resistance to UV and oxidative degradation as compared to conventional products while still providing the required barrier and mechanical properties.
