This company plans to present its latest developments on low free (LF) isocyanate urethane systems for adhesives, sealants, and one-component foams (OCF) at the FEICA Conference and Expo, taking place September 12-14 in Riga, Latvia. Under the brand name Adiprene LF, low free isocyanate urethane prepolymers have been developed for use in adhesives, sealants, and one-component foams. The LF technology reportedly creates prepolymers with < 0.1% free MDI (methylene diphenyl diisocyanate) and other isocyanates such as TDI (toluene diisocyanate), HDI (hexamethylene diisocyanate) or pPDI (p-phenylene diisocyanate). These prepolymers are particularly suited to address increasingly strict regulatory requirements and provide for final products with lower hazard classifications.
