Widely used in the electronic, aerospace, optical and specialty OEM industries, Master Bond EP126 excels in high temperature applications up to 600° F.
Widely used in the electronic, aerospace, optical and specialty OEM industries, Master Bond EP126 excels in high temperature applications up to 600° F. This two component product features unique handling properties as Part A is a moderate viscosity liquid and Part B is a powder. It can be easily mixed using a forgiving 100 to 50 ratio by weight.
The mixed system is a malleable paste, with an exceedingly long open time of more than 5 days for a 100 gram batch. The curing is straightforward; 3 to 4 hours at 300° F or 2 to 3 hours at 350°F.
EP126 adheres well to many substrates including metals, composites, glass, ceramics, rubbers and many plastics. It offers a high tensile lap shear strength, tensile modulus and compressive strength of over 2,800 psi, 425,000 to 475,000 psi and 32,000 to 34,000 psi, respectively.
This epoxy compound resists a variety of chemicals such as water, oils, acids, bases and many solvents. Additionally, it is formulated as a toughened system allowing it to withstand rigorous thermal cycling.
EP126 is dimensionally stable, has low shrinkage upon curing and is machineable. It also is a good electrical insulator, especially as it retains high dielectric strength at elevated temperatures.
When used as an adhesive and sealant, EP126 can be conveniently applied with a spatula or knife. This product has a service temperature range of -80° to 600° F. EP126 features a shelf life of 6 months in its original, unopened containers and is available in kits ranging from ½ pints to 5 gallons.
