About Conductive Adhesives and Compounds

Conductive adhesives and compounds provide an electrically and/or thermally conductive path between components. Electrically conductive adhesives and compounds provide low resistivity and are used to prevent electrostatic discharge (ESD), electromagnetic interference (EMI), and radio frequency interference (RFI). They are also used in thick film metallization and electrical interconnections. To improve heat dissipation, thermally conductive adhesives and compounds are applied between a heat-generating electrical device and a heat sink. These products are designed to form a thermally conductive layer, either between components or within a finished product. Both electrically conductive and thermally conductive adhesives and compounds are available in many forms. Examples include adhesive and casting resins, molding and potting compounds, greases and pastes, encapsulants, and conformal coatings.

Products & Services Related to Conductive Adhesives and Compounds

Conformal Coatings

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.

Epoxy Adhesives

Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.

Gel Elastomers

Gel elastomers are highly viscoelastic polymer gel materials that have excellent shock absorption and damping characteristics. They are available in a variety of material types and grades.

Pressure Sensitive Adhesives (PSA) and Contact Adhesives

Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.

Silicone Adhesives and Sealants

Silicone adhesives and sealants have a high degree of flexibility and a very high temperature resistance (up to 600° F), but lack the strength of other epoxy or acrylic resins.

Thermoplastics and Thermoplastic Materials

Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.

Thermosets and Thermoset Materials

Thermosets and thermoset materials are crosslinked polymeric resins that are cured or set using heat or heat and pressure. They generally have a higher resistance to heat than thermoplastics.
