Master Bond EP62-1BF is a two part epoxy featuring the ability to withstand exposure to aggressive chemicals including acids, bases and solvents, even at high temperatures. “We tested the chemical resistance properties of EP62-1BF by taking cured samples of the system and immersing them in a variety of chemicals, like sulfuric acid, toluene, ammonium hydroxide, etc.,” said Venkat Nandivada, manager of technical support. “Even after six months, the samples weren’t affected by chemicals.”

EP62-1BF is easy to handle with a long open time of 12-24 hours at 75°F for a 100 gram batch. It has a non-critical mix ratio of 100 to 5 by weight and offers a variety of cure schedules at moderately elevated temperatures from 140-257°F [60-125°C]. With a mixed viscosity of 2,000-5,000 cps, EP62-1BF can be used for potting small components. Additionally, it has low shrinkage upon curing.

After curing, this compound delivers an impressive strength profile with a tensile lap shear strength of 2,000-2,200 psi, a tensile strength of 8,000-9,000 psi and a tensile modulus of 500,000-550,000 psi. EP62-1BF is thermally stable and has a glass transition temperature (T_g) of 125-135°C and is serviceable over the wide temperature range of -60°F to +400°F [-51°C to +204°C]. This formulation is also a competent electrical insulator with a volume resistivity exceeding 10¹⁴ ohm-cm.

Its combination of chemical resistance, thermal stability and physical strength properties enable this product to be used for many applications in the aerospace, electronic and specialty OEM industries. EP62-1BF is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits, as well as premixed and frozen syringes.

Certified to meet ASTM E595 NASA low outgassing standards, Master Bond EP46HT-2AO Black is well suited for the aerospace, electronic, opto-electronic industries and can be used vacuum environments. This two component system blends thermal stability with a high strength profile for a variety of bonding, sealing and encapsulation applications.

EP46HT-2AO Black combines superior thermal conductivity of 9-10 BTU•in/ft²•hr•°F [1.2981-1.4423 W/(m·K)] and reliable electrical insulation with a volume resistivity exceeding 10¹⁴ ohm-cm at room temperature. It has a glass transition temperature of 200-210°C and is serviceable over the wide temperature range of -100°F to +500°F [-73°C to +260°C]. This dimensionally stable system delivers a tensile strength of 6,000-7,000 psi, compressive strength of 26,000-28,000 psi and tensile lap shear strength of 1,400-1,600 psi at 75°F. EP46HT-2AO Black also withstands a variety of chemicals including oils, water, acids, bases and fuels.

Unlike most traditional two part epoxies, EP46HT-2AO Black cures with the addition of heat, which allows it to have a working life of over 24 hours. It has a forgiving 100 to 30-35 mix ratio by weight and upon mixing, this thixotropic system has a viscosity of 140,000-280,000 cps. It bonds well to metals, composites, glass, ceramics, rubbers and many plastics.

This epoxy is available in ½ pint, pint, quart, gallon and 5 gallon container kits. Part A of this system is black in color and Part B is gray. EP46HT-2AO Black has a minimum 6 month, maximum 1 year shelf life at ambient temperatures in original, unopened containers.

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; 3-4 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.

EP126 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.
