MATERIALS: Master Bond has released a high temperature epoxy for service above 500F. EP125 is a toughened, two part epoxy designed to withstand exposure to boiling acids, alkalis, salts, fuels and most organic solvents. It develops durable bonds between metallic and nonmetallic surfaces. The heat resistant adhesive features excellent dimensional stability in addition to superior electrical insulating properties. Thermally stable bonds retain their pertinent physical profile and chemical resistance even after prolonged exposure to extreme temperatures.EP125- heat resistant epoxy achieves a lap shear strength on the order of 2,500 psi at ambient temperatures. After heat aging for 1,000 hours at 500F, an excellent, near 50 percent of the original bond strength, is retained. Castings exhibit flexural strength as high as 15,000 psi and a flexural modulus of more than 500,000 psi. 100 percent reactive, solvent and volatile free, the high temperature sealant/coating cures at elevated temperatures. Cure cycles can be widely adjusted so as to best meet specific processing needs. Master Bond’s improved high temperature epoxy is recommended for bonding, casting, laminating and sealing applications where exceptional long term resistance to heat and aggression is imperative.
