Li-Ion Battery Potting Compound Options Include:
Epic Resins 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. RM2018 also features a convenient 4:1 volumetric mix ratio, low-Tg, and excellent electrical stability over various frequencies.
S7527 Product Description:
Epic S7527 is a two-component urethane potting material formulated to provide a long gel time at a medium hardness. S7527 has a UL 94V-0 recognized flame rating at 9mm without the use of phosphate or halogen-containing flame retardants. S7527 is made from RoHS compliant ingredients. S7527 has excellent thermal properties and water resistance.
Epic S7571 Description:
Epic S7571 was developed for the lithium-ion battery market. It features a very low Tg (<-60°C), is flexible (80 shore A), is designed to pass UL 94 V-0 at ¼", and has decent thermal conductivity (0.6-0.7 W/mk) for material that has a lower density than most other UL 94 V-0 systems. The reduced density decreases the weight of the finished product while maintaining the thermal conductivity needed.
S7475 Product Description:
Epic S7475 is a two-component polyurethane compound for potting electronic control modules (ECM’s) and a wide variety of electronic devices. The low mixed viscosity of the S7475 allows the material to flow into intricate areas under printed circuit boards and other tight tolerance areas. Another key property of this product is the 4:1 by volume mix ratio that 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, therefore allowing delicate surface mounted devices (SMD's) to expand and contract during thermal cycling and thermal shock. For applications that generate a great deal of heat, S7475 has shown extremely low weight loss at 130°C. S7475 is UL 94 V-0 recognized at 4.8 mm and is RoHS compliant.
