EP110F8-5 High Performance Epoxy


Developed for potting, sealing, encapsulation and casting applications, EP110F8-5 is dimensionally stable and has low shrinkage upon cure. This system 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.


This two component epoxy 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 250-300°F in 4-6 hours. EP110F8-5 has a very long pot life of 2-3 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 40-60%. 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 18,000-20,000 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 ½ pint, pint, quart, gallon, and 5 gallon container kits.
