Encapsulants

Similar to sealants and coatings, encapsulants provide environmental protection for individual electronic components such as diodes, capacitors, and integrated circuits (IC), as well as wire leads and other fragile connectors. The encapsulant’s composition must reflect high ionic purity, and preferred cured properties include moisture resistance, invulnerability to thermocycling, low shrink, and flexibility from a low modulus value. Low shrink and flexibility are significant as the encapsulant also functions as a strain relief for fine wire leads. Lower stress minimizes the risk of wire breakage.

Encapsulants offered by Tangent have been formulated with all these desirable properties in mind. Tangent’s line of encapsulants offers excellent adhesion to substrates associated with PCB and FPC assembly, including polyimide, metals, FR-4 (glass-epoxy), PET, polycarbonate, ceramic, and glass. They are offered in a range of viscosities to better support numerous component geometries. For example, in order for the encapsulant to create a uniform coating (shell) on sharp-edged components, it should generally be higher in viscosity and thixotropic.

As their exclusive distributor for the Americas, Tangent offers encapsulants from Panacol, under the Structalit® and Elecolit® brand names. Panacol-Elosol GmbH is a member of the Hönle Group headquartered in Germany, and has been formulating and manufacturing adhesives for over 30 years.
