Radio Frequency (RF) Potting and Encapsulating Compounds

Epoxy Adhesives and Polyurethane Potting Compounds for Radio Frequency Applications


Epic Resins has a variety of epoxy polyurethane resin compounds for casting radio frequency devices, such as automatic meter readers (AMR's). The low dielectric constant up to 1 GHz can be used for applications in frequencies in the 433/868 MHz band. We also have adhesives for low-frequency transmission over short distances, such as security card readers.

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 conditions.

Radio Frequency Potting and Encapsulating (RF)

High-Temperature Resistant Epic S7527 for Potting Radio Frequency Devices

Not all radio frequency devices or meter readers are located in dry, safe locations. This creates a problem because these devices need to work properly in order to provide optimal clarity. Epic Resins has introduced a two component polyurethane potting compound to protect radio frequency devices. By creating a product with greater adhesion and moisture vapor permeability resistance at an affordable cost, Epic Resins adds another material to keep your equipment safe in the hardest conditions.

Some Examples of RF Potting Compounds Available at Epic Resins:

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 3GHz 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 S7341 - 2 Component Epoxy w/ High Optical Clarity 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. The optical clarity of this material is key for applications in which visibility to LED’s 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 exothermal temperatures are essential for applications with temperature sensitive components.

Epic RM 2017 - Polyurethane Compound with Low Dielectric Constant

Epic RM2017 is a two-component polyurethane potting compound designed for use in low to high-frequency RF applications. Epic RM2017’s low dielectric constant, coupled with its other electrical properties, allow the user to successfully transmit lower frequency signals over greater distances with low signal loss.

Epic S7493 - 2-Component Epoxy Potting Compound for RFID Tags

Epic S7493 is a two-component epoxy potting compound designed with a convenient volumetric mix ratio and a fast cure schedule at a moderate temperature for optimum properties. The cured epoxy is affected minimally by 100% RH and retains a significant portion of room temperature strength between - 54°C and 94°C. The unique combination of physical properties coupled with a low dielectric constant makes this product an excellent candidate for RFID tag potting over a wide range of frequencies.
