Master Bond Unveils Chemical Resistant, Two Part Epoxy
Master Bond has unveiled EP126, a chemical resistant and two-part epoxy. The epoxy is widely used in the electronics, aerospace, optical and specialty OEM industries.

Properties of Master Bond EP126


  • It excels in high temperature applications up to +600°F. 
  • It 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; 3-4 hours at 300°F or 2-3 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, 425,000-475,000 psi and 32,000-34,000 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.

Features of Master Bond EP126


  • It is dimensionally stable, has low shrinkage upon curing and is machineable. 
  • It also is a very 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°F 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.
