Silicones for Electronic Protection and Long-term Performance
Electronics function in many different applications. However, there is a common requirement to protect sensitive components and systems from moisture and harsh environmental elements. As the electronic operates, there are also other factors that need to be avoided, which can cause malfunction and premature failure such as vibration, shock, and stress caused by temperature fluctuation during thermal cycling.
Material options for electronic protection include silicones, epoxies, polyurethanes, and other various polymers. Silicones are extremely durable and feature important and versatile physical properties, contributing to design flexibility, process efficiency, and long-term performance.
CHT offers an extensive portfolio of silicone technology that addresses different challenges and meets design requirements for today’s electronic applications.
CHT’s silicones perform in the following industries:
- Automotive
- Traction and railway
- Aviation and aerospace
- Defence/military sectors
- LED and lighting
- Telecommunication
- Measurement and control
- Household appliances
- General industrial & electronics applications

Thermal Management
With the continued miniaturization and expanding population of components that comprise electronic devices, mitigation of generated heat is an ongoing issue. CHT offers a series of silicone adhesive sealants, encapsulation and potting compounds, silicone gels, gap fillers and non-setting compounds for heat dissipation.
For more information, please visit our Thermal Transfer page.
Neutral Cure Adhesives
The CHT patented Acetone and the Alkoxy range of 1 and 2-part RTV silicone adhesive sealants are compatible for use within electronics. They can be used to bond components on printed circuit boards and will not damage sensitive metals, such as copper.
For more information, please visit our Neutral Cure Adhesives page.
Silicone Grease
Silicone greases are formulated to provide very durable, non-setting, work stable products used to lubricate, electrically insulate and act as a heat transfer medium. They provide excellent protection against moisture and other harsh environmental conditions.
For more information, please visit our Silicone Grease page.
Encapsulation and Potting
CHT’s silicone potting compounds and encapsulants are used when a deep section cure is required and endure extreme temperatures while protecting electronic components from shock and vibration, moisture, and other atmospheric contaminants. The hardness of these silicones, ranges from a gel-like consistency to a hardened rubber.
For more information, please visit our Encapsulation and Potting page.
Silicone Gels
Silicone gels area often used when a soft and highly flexible encapsulation is required. CHT’s silicone gels are available in a variety of hardnesses, penetrations and viscosities, and typically provide a primerless, “pressure sensitive” type bond to most substrates.
For more information, please visit our Silicone Gels page.
Conformal Coatings
Silicone conformal coatings are applied as a thin layer across the surface of the board to cover all components and delicate wiring. CHT’s conformal coatings adhere well to most components and substrates, maintain their physical properties in extreme temperatures, are contaminant & corrosion resistant, flow easily around components, and contain a UV tracer for visual quality control inspection.
