About Electrical Resins and Electronic Compounds

Electrical resins and electronic compounds are adhesives, greases, pads, stock shapes, tapes, encapsulants, potting compounds, thermal interface materials, and electrically conductive substances used in electrical, electronic, and semiconductor applications. There are several basic types of electronic resins and electronic compounds. Electrically conductive products provide low resistivity and are often used to prevent electrostatic discharge (ESD), electromagnetic interference (EMI), and radio frequency interference (RFI). They are also used in thick film metallization and to provide electrical interconnections at both the device and circuit board level. Thermally conductive electrical resins and electronic compounds are applied between a heat-generating electrical device and a heat sink in order to improve heat dissipation. These products form a thermally conductive layer, either between components or within a finished product. Thermal interface materials that use a phase change are also available.

Products & Services Related to Electrical Resins and Electronic Compounds

Conductive Adhesives and Compounds

Conductive adhesives and compounds provide an electrically and/or thermally conductive path between components.

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.
