RFI-Temp© Shielding© - Product Information
 

RP Tempering™ Technologies would like to introduce our new RFI Shielding product line featuring your choice of multiple highly conductive 1 to 3 micron sized conductive particles. RFI-Temp© offers our customers multiple easy to follow application techniques for every EMI & RFI Shielding Product. RFI-Temp© is easy to apply, dries fast and is cost effective verses sending out to an RFI Shielding House, at a premium part price, long lead times & setup cost for masking fixtures.

The most common electrical property applications are for EMI/RFI shielding. The initials “RFI” stand for Radio Frequency Interference. RFI for the most part is EMI within the range of 1kHz-10GHz. Radio Frequency Interference shielding can be achieved by using highly conductive materials, such as 1 to 3 micron sized copper, aluminum or nickel particles. RFI Shielding is done for two primary reasons:
• To keep electronic device from interfering with others
• To keep other devices from interfering with yours.
RFI-Temp© Shielding was developed for low volume use for rapid prototypes (all SFF materials & systems), injection molded plastics and many other materials. This particular shielding product has copper/aluminum/nickel combined. Some of our conductive coatings can even reflect the interfering radiation light waves.

Shielding against magnetic fields is difficult. Our EMI/RFI products should be effective as energy is reflected. Then when the rest of the energy is transmitted across the surface boundary, absorption further attenuates it. This way we can meet certain applications by inhibiting electro magnetic waves and impeding the field. Most metals have low impedance. Low impedance energy is more likely to be absorbed. If the electrical field wave impedance is high most of the energy is likely to be reflected.
"Typical applications for RFI Shielding are enclosures for Mobile Phones, Radios, & Two Way Communication Devices"

Wetted RFI-Temp© Coating – The copper/aluminum/nickel particles dispersed in our carrier solution will meet most common RFI shielding applications. Effective in the 1kHz to 10GHz range and blocking decibel ranges from 20dB to 60dB by 85% to 95%. Apply by masking the specified area to be shielded. Next either brush or spray on the Wetted RFI-Temp© per our tempering instructions to meet your required specification. RP Tempering™ has developed a portable spaying system for applying any of our dispersed particle shielding products. See our website or ask a customer representative for more details.

Dry RFI-Temp© Kit – To achieve higher conductivity applying a blend of dry copper/aluminum/nickel particles to the actual surface substrate may be required in single and/or multiple layers. Masking of the application area is usually required before applying the tempering materials. Brush the particles on like a coat of paint with the foam brush supplied in the kit. Next, seal the particles to the surface by applying the carrier/sealer resin also supplied in the kit per our tempering instructions. Effective in the 500MHz to 900MHz range and blocking decibel ranges from 65dB to 80dB by 95% to 97%.
