Radio Frequency (RF) Potting and Encapsulating Compounds

We offer a variety of epoxy and polyurethane compounds for potting and encapsulation of radio frequency and wireless sensor applications. This includes automatic meter readers (AMR's), NFC devices, RFID tags, tire pressure management sensors (TPMS) and Internet of Things (IoT) devices that use the following protocols: Wi-Fi, Bluetooth, Zigbee, and Z-Wave. Our potting compounds are used for devices that operate in the 433/868 MHz bands, such as security card readers. We also have materials for devices that operate from 1-3 GHz.

If you require RF transparency or optical clarity, we also have clear compounds. These are useful in water and gas meter reading devices where you need to read a barcode. We offer materials with low Tg (glass transition temperature) and low hardness suitable for outdoor applications to protect electronics from harsh thermocycling conditions. Many of our potting materials are UL rated and certified with enhanced fire resistance.

Custom RF Formulations

If you do not see an epoxy or polyurethane that meets your needs, we can develop one for you. We custom-formulate for shorter production runs as well as ongoing bulk supply to high-need manufacturers. We have decades of experience as a formulator and manufacturer of epoxy and polyurethane resins. Let us help you reduce your time to market and give you a consistent product to ensure smooth production.
