Master Bond Polymer System Supreme 3HT-80 is a one component, heat curing epoxy adhesive/sealant featuring excellent physical and chemical resistance properties and a minimal curing temperature of 170°-175°F - well below the 250°-300°F required by typical one part epoxies. At 175°F, Supreme 3HT-80 will cure in 30 minutes and at 250°F, it will cure in 10 minutes. Optimal physical properties are obtained after a 30 minute cure at 250°F. No mixing is required prior to use and the working life is unlimited. Unlike premixed and frozen systems which require special low temperature storage, Supreme 3HT-80 can be conveniently stored in conventional refrigerators. The shelf life of Supreme 3HT-80 at room temperature is 6-8 weeks and at 40-50°F is a minimum of 3 months and a maximum of 6 months.
