Battery Potting and Encapsulation Compounds

Epic RM2018 is a two-component polyurethane potting and encapsulating compound that carries a UL94 V-0 flammability rating. RM2018 is designed for potting DC/DC converters, GPS sensors, and other electronic devices that require flexibility over a wide temperature range. It is designed to operate from -40C to 130C. RM2018 also features a convenient 4:1 volumetric mix ratio, low Tg and excellent electrical stability over various frequencies.

Epic S7253 series of products are two-component, UL 94V-0 recognized polyurethane compounds designed for electronic applications requiring encapsulation. The low weight loss of the S7253 series at elevated temperature shows that this product is suitable for applications that can reach up to 125°C. The S7253 series is currently utilized in a variety of applications, including automotive applications that require thermal cycling between -40°C and 85°C. The S7253 series of products feature good thermal conductivity along with good adhesion to various metals and plastics. The S7253 product series meets RoHS requirements.

Epic S7302 is a tough urethane material designed for electronic potting applications. The chemistry of S7302 lends itself well to products that are exposed to a wide range of temperatures. S7302 is adequate for applications that are thermally cycled between -40°C and 135°C with excursions up to 160°C. S7302 also features good moisture resistance and good adhesion to various metals and plastics.

Epic S7475 is a two-component polyurethane compound for potting electronic control modules and a wide variety of electronic devices. Low mixed viscosity allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. A 4:1 mix ratio allows the system to be very adaptable for meter mix and dispense processing. The very low hardness of S7475 in combination with the low Tg provides excellent flexibility, allowing delicate surface-mounted devices to expand and contract during thermal cycling and thermal shock. For applications that generate high heat, S7475 has shown extremely low weight loss at 130°C. It is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.

Epic S7592 is a two component polyurethane adhesive designed to pass UL 94 V-0 flame retardant testing. S7592 features a convenient 2:1 mix ratio by volume with a high mixed viscosity. S7592 has been formulated to provide superior adhesion to a variety of substrates, including plastic and metal.

Epic S7594 is a two component polyurethane potting compound designed with a very high thermal conductivity combined with a long gel time. S7594 has been formulated to meet a UL 94 V-0 flame rating at a thickness of 12.5mm in screening tests.
