Room Temperature & Thermal Cure Epoxies

Epoxies continue to evolve and improve. New single and two-component epoxy introductions are stronger, faster curing, and easier to work with. As an alternative to light curable adhesives, epoxies overcome challenges presented by shadowed bond lines and opaque substrates. They exhibit minimal shrinkage, and offer superior chemical and environmental resistance. Their non-photonic curing mechanisms allow them to be opaque in color, and they can be filled with thermally and electrically conductive materials.

As their exclusive distributor for the Americas, Tangent Industries offers room temperature and thermally curable epoxies from Panacol-Elosol. With an expertise in epoxy development, Panacol-Elosol GmbH is part of the Hönle Group headquartered in Germany. They have been formulating and manufacturing adhesives for over 30 years. Panacol epoxies are packaged under the brand names of Structalit® and Elecolit®.

Structalit® epoxies are high performance adhesives, delivering superior strength, thermal stability, and chemical resistance. The epoxies form incredibly high strength structural bonds that are demanded in panel assembly, frame attachment, and ferrite bonding. In addition, select products are ideal for sealing and encapsulating (glob top) electronic and electrical components such as smart cards. They are also ideal for potting and casting applications. Structalit® products are available as single component or two component systems. The single component adhesives offer easy dispensing and fast, thermal curing. Two-component epoxy systems can be cured at room temperature or accelerated with heat. Various pot-life schedules are available to accommodate the infinite number of global production processes.

Elecolit® epoxies combine thermal and electrical conductivity with excellent bond strength. The electrically conductive epoxies are ideal for antenna printing, die bonding, and other electronic assembly associated with PCB, FPC, and LCD production. The thermally conductive epoxies facilitate heat transfer, and are typically used to affix heat sinks and power modules.

Electrical conductivity is typically achieved by filling the adhesive with metallic materials such as gold, silver, or nickel. Metallic fillers also offer the best thermal conductivity, which enables the electrically conductive epoxies to serve a dual function. However, if thermal conductivity is required without the possibility of electrical conductivity, Elecolit® offers epoxies containing non-metallic fillers. Elecolit conductive epoxies are available as one or two component systems.
