We encounter electronics everywhere in the most diverse areas of application. No matter how differently electronics are designed, the protection of components and systems from moisture and harsh environmental conditions is always of great importance.
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 extreme temperature fluctuation.
Materials used for electronic protection are usually silicones, epoxy resins, polyurethanes and various other polymers. CHT Silicones in particular are excellent for electronic components because they are durable and have crucial physical properties that support the long-term performance of electronics. In addition, silicones are extremely flexible in design and manufacturing processes.
CHT offers a versatile range of silicone technologies to meet all requirements of modern electronics.
Containment and dissipation of generated heat is a constant topic in electronics. Precisely because components are becoming smaller and smaller and many system components are located in the tightest of spaces. Especially for this purpose CHT offers a series of silicone adhesive sealants, encapsulation and potting compounds, silicone gels, gap fillers and non-setting compounds for efficient heat dissipation.
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.
Silicone greases are 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.

CHT’s silicone potting compounds and encapsulants are used when a deep section cure is required They 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.
Silicone gels are 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.
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.
