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, lowTg and excellent electrical stability over various frequencies.
Epic S7475 is a two component polyurethane compound that was formulated for potting electronic control modules (ECM's). The low mixed viscosity of the S7475 allows the material to flow into intricate places under printed circuit boards and other tight tolerance areas in a wide variety of electronic devices. Another key property of this product is the 4:1 by volume mix ratio that makes the system very adaptable to meter mix and dispense applications. Offering a hardness of Shore OO = 50-65, the S7475 provides excellent flexibility, therefore allowing delicate surface mounted devices (SMD's) to expand and contract during thermal shocks and thermal cycling. For applications that generate a great deal of heat, this product is also an excellent choice due to its low weight loss at elevated temperatures. S7475 has shown extremely low weight loss at 130C - 0.24% after 168 hours. As with all polyurethane chemistries, the S7475 requires safe handling precautions such as desiccant canisters in drum bungs and inert gas purging of opened containers with nitrogen or argon. Moisture contamination of the product should be avoided at all costs as the product will react with moisture to produce CO2 as a byproduct causing foaming. S7475 is free of heavy metals and PBDE's and is RoHS compliant. S7475 meets UL94V-0 at 4.8mm.
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.
