Potting Compounds for Sensors


Custom Sensor and Transducer Potting Resins

Quality Potting Compounds Available at Epic Resins Include:

Epic S7224 - 2 Component Epoxy Potting Compound

Epic S7224 is a two-component epoxy potting compound. S7224 is thermally conductive in order to transfer heat out of parts potted with it. Epic S7224 is especially useful in harsh, under-the-hood automotive applications requiring a durable, chemically resistant epoxy potting compound.

Epic S7341 - 2 Part Epoxy Potting/Encapsulating Compound

Epic S7341 is a two-component epoxy potting and encapsulating compound designed with a low exotherm and a convenient 2:1 by volume mix ratio. Because of its high clarity, Epic S7341 is used in applications where items such as barcodes must be read through the potting compound.

Epic S7379 - 2 Component Epoxy Potting Compound

Epic S7379A/B is a two-component epoxy potting compound designed to provide crack resistance in applications requiring harsh thermocycling of the encapsulated part. Epic S7379 displays good adhesion to most metal and plastic cases. With these two characteristics, Epic S7379 is an excellent choice for applications encountering problems due to moisture infiltration.

Epic S7151 - 2 Component Epoxy Resin Electrical Potting/Casting

Epic S7151 is a two-component general purpose epoxy resin electrical potting/casting compound. Epic S7151 is an excellent choice for many electrical potting applications and features a meter-mix friendly 3:1 mix ratio, very low shrinkage and good adhesion to both metal and plastic cases. S7151 retains a high gloss in the cured state resulting in very attractive parts.

Epic R1016/H5008 - Impact Resistant Potting System

Epic R1016/H5008 is an impact resistant potting system that has been qualified per NAV AIR drawing 790AS743. The system has been approved especially effective for potting electronic components used in a variety of ballistic vehicles. Delicate components, e.g. glass diodes, should be coated with a resilient material such as silicone rubber to minimize stresses developed during curing.


Sensor potting compound for harsh environment protectionPotting Materials for Automotive Sensors

Automotive sensors are put through some extreme environmental stresses and require durable protective potting for the sensitive electrical components within sensor systems. Epic Resins' potting compounds and encapsulants provide the protective properties necessary for these essential automotive parts. We are also fully capable of adjusting product formulations to better meet the specific needs of whatever part you're building. Whatever your potting and encapsulation requirements, we'll work with you to get you the materials you need.
