Thermoset 300/67 Epoxy System Where to Buy
Product Information
LORD Thermoset 300/67 epoxy system is a two-component, general purpose filled epoxy system which offers superior thermal conductivity, improved shock resistance and lower coefficient of thermal expansion compared to unfilled epoxy systems.
Handling and cured properties of the two-component epoxy system are dependent on the hardener used with Thermoset 300 epoxy resin.
Shelf Life
Shelf life of Thermoset 300 resin is one year from date of manufacture when stored at 25°C in original, unopened container. The material must be periodically rotated within its container to minimize settling.
Shelf life of Thermoset Hardener No. 67 is 18 months from date of manufacture when stored in a well ventilated area at 25°C in original, unopened container.
Features and Benefits
Elevated Temperature Cure – requires an elevated temperature cure to obtain a rigid bond.
High Temperature Resistant – provides good resistance for cured system that experiences continuous operating temperature up to 155°C.
