Low-viscosity, plasticizer-free SPUR+ prepolymer allows freedom in formulating sealants
Formulations developed using this technology offer fast room-temperature cure and good durability, and the adhesives or sealants they produce are free of unreacted isocyanates, allowing them to have a less harmful impact on the environment. Benefits of the resulting products also include no bubbling during cure, and a broadening of the formulation latitude compared to conventional polyurethane technologies.
