Developed for potting, sealing, encapsulation and casting applications, Master Bond EP110F8-5 is dimensionally stable and has low shrinkage upon cure. This two-component epoxy features superior electrical insulation properties including a volume resistivity exceeding 1015 ohm-cm, a dielectric constant of 2.91 at 1 KHz and a dissipation factor of 0.009 at 1 KHz. “EP110F8-5 is an easy to use, heat curing epoxy that is ideal for applications where dimensional stability, electrical insulation properties and thermal cycling resistance are required,” said Rohit Ramnath, senior product engineer.
According to the company, the product has a very forgiving one to two mix ratio by weight with a moderate mixed viscosity of 7,000 to 11,000 cps and good flow properties. It requires an elevated temperature cure at 250 to 300°F in 4 to 6 hours. EP110F8-5 has a long pot life of 2 to 3 days at room temperature.
EP110F8-5 is a rigid system with a Shore D hardness of 70-80, but also maintains excellent toughness and offers an elongation of 40 to 60%. Its toughness imparts an ability to withstand thermal cycling as well as impact and vibration. In fact, it passes 10 thermal shock cycles of -55° to 125°C. With a compressive strength of 18,000 to 20,000 psi, EP110F8-5 adheres well to a wide variety of substrates, including metals, composites, glass and many plastics. It resists exposure to water, oils and fuels.
It is serviceable over the wide temperature range of -100° to 300°F (-73° to 149°C). Part A of EP110F8-5 is tan in color and Part B is brown. This system is available for use in half-pint, pint, quart, gallon and 5 gallon container kits.
