Overnight Cure Urethane Elastomers - Rigid


This selection of harder polyurethanes have a wide variety of end uses including prototyping thermoplastic-like parts, constructing molds for low volume metal forming applications, and making heat resistant foundry tooling. All of these products have a long gel time to provide the user sufficient time to vacuum degas prior to pouring. A 16-18 hour cure time is required before demolding.
