Radio Frequency (RF) Potting and Encapsulating Compounds

Epoxy Adhesives and Polyurethane Potting & Encapsulation Compounds for Radio Frequency Applications

Epic Resins has a variety of epoxy and polyurethane resin compounds for potting and encapsulation of radio frequency devices, such as automatic meter readers (AMR's), NFC devices, and Internet of Things (IoT) devices that use the following protocols: Wifi, 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.

Our epoxy and polyurethane potting compounds are excellent for a wide variety of radio frequency and wireless sensor applications, including RFID tags and Tire Pressure Management Sensors (TPMS). If you require RF transparency or optical clarity, we have clear compounds. These are useful in water and gas meter reading devices where you need to read a barcode. Our epoxy adhesives are also crack resistant. Low Tg (glass transition temperature) and low hardness formulations are suitable for outdoor applications where you need to protect electronics from harsh thermocycling conditions.

Epic Resins has decades of experience as a formulator and manufacturer of specialty epoxy and polyurethane resins. Our professional staff uses superior customer service to work with clients to solidify their manufacturing production process. Many of our potting materials are UL rated and certified for enhanced fire resistance. Our expertise helps clients to reduce their time to market and our product consistency ensures a smooth production ramp up.

Custom RF Potting Resins by Epic Resins

If you do not see an adhesive that meets your needs, we can develop one for you in our research laboratory. We do custom formulations for shorter production runs as well as ongoing bulk supply to high-need manufacturers. We employ advanced testing procedures to develop high-quality resin materials for the manufacturing of OEM radio frequency tags and components.

Some Examples of RF Potting Compounds Available at Epic Resins:

Epic S7341 2-Component Epoxy System for AMRs

Epic S7341 is a two-component epoxy system designed for potting automatic meter readers (AMRs) for the water meter market. This compound has more than 10 years of field experience in this application. The optical clarity of this material is key for applications in which visibility to LEDs or barcodes under the potted surface is important. EPIC S7341 maintains a low dielectric constant up to a frequency of 1 GHz and allows this system to be used in applications with frequencies in the 433/868 MHz band. The excellent physical properties and electrical properties over an extended temperature range make this an ideal candidate for rugged applications. The long work life and low exotherm are essential for applications with temperature-sensitive components.

Epic S7325 2-Component Polyurethane Potting Compound for Bluetooth and Automotive

Epic S7325 is a low-hardness, two-component polyurethane electrical potting compound designed for automotive applications. Additionally, the superior stability of the dielectric constant up to frequencies of 3 GHz makes Epic S7325 an ideal candidate for various RF and Bluetooth applications. The low glass transition temperature and good stability up to 125°C allow this material to be used in wide temperature range applications. The convenient 1:1 volumetric mix ratio makes this material easy to dispense using meter mix and dispense equipment.

Epic S7379 2-Component Epoxy System for AMRs and AMI

Epic S7379 is a two-component epoxy system designed for potting automatic meter readers (AMRs) and advanced metering infrastructure (AMI) applications for the gas metering market. Designed around our popular S7341, EPIC S7379 is formulated with improved crack resistance which is critical for handling the thermal shock outdoor environment applications endure. The low dielectric constant allows this system to be used in applications in frequencies of 433/868 MHZ band.

Epic S7527 2-Component Polyurethane UL 94V0 Certified

Epic S7527 is a two-component polyurethane that is UL 94V0 recognized and has achieved this rating without the use of halogen-containing flame retardants. The S7527 features a medium hardness, extended gel time, improved filler stability and low water absorption. The 5:1 by volume mix ratio makes this material meter mix and dispense machine friendly. This polyurethane is suitable for RF applications with short distance transmit ranges such as access card readers.
