Deep Coat: Pioneering EMI & RFI Shielding Solutions for Over Four Decades

In today’s high-frequency, high-stakes electronic environment, electromagnetic interference (EMI) and radio frequency interference (RFI) can jeopardize the performance and reliability of critical electronic systems. That’s where Deep Coat comes in—a trusted name in the EMI and RFI shielding industry since 1981. With a singular focus on delivering high-performance shielding solutions, Deep Coat has become an industry leader in vacuum metallization and electromagnetic shielding for military, medical, and commercial applications.

The Legacy of Deep Coat

Founded with a mission to engineer superior EMI shielding, Deep Coat has continuously pushed the boundaries of innovation in the field. What began as a company producing shielding solutions for printed circuit boards has since evolved into a full-spectrum manufacturer of EMI and RFI shielding products. Today, Deep Coat’s advanced coatings are used in everything from military-grade PCB shields to large molded enclosures for medical equipment, electronic connectors, instrument housings, and communication systems.

With over 35 years of expertise, Deep Coat’s proprietary vacuum metalization process stands as a testament to the company’s commitment to precision, performance, and reliability.

Advanced Shielding with Vacuum Metalization

Deep Coat is best known for its unique vacuum metalization process—a method that allows up to four different layers of metals to be applied within a single vacuum draw. This capability is critical for creating custom shielding solutions that meet the precise needs of each application.

Using this technique, Deep Coat can apply metal layers ranging from 0.3 to 24 microns, even on highly complex plastic geometries. The result is a uniform, durable coating that ensures high-level EMI and RFI attenuation across a wide frequency spectrum.

The flexibility of this process allows Deep Coat to use a variety of metal combinations, helping customers maximize shielding effectiveness while maintaining material compatibility and adhesion integrity.

A Proven Leader in Adhesion Technology

One of the key challenges in vacuum metalization is ensuring consistent metal-to-substrate adhesion, especially on non-metallic or irregular surfaces. Deep Coat addressed this problem head-on with the development of “in-chamber” RF plasma pretreatment. This proprietary technique enhances the surface of plastics and other non-conductive materials before metal application, significantly improving adhesion and long-term durability of the coating.

This innovation—along with other patented technologies developed by Deep Coat—has helped the company deliver consistently high-quality shielding solutions where other providers may fall short.

The Patented 4-Layer Shielding System

Among Deep Coat’s many technological advancements is its patented four-layer shielding system, which includes:

A base layer of stainless steel for durability and corrosion resistance

Two intermediate layers of copper for superior conductivity and shielding

A final stainless steel overcoat for added protection and environmental resilience

This multi-metal design offers a perfect balance of electrical performance and mechanical toughness, making it ideal for mission-critical applications in aerospace, defense, telecommunications, and healthcare sectors.
