Tra-Con Tra-Duct 2929 Room Temperature Conductive Flexible Silver Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy, Electrically Conductive; Filled/Reinforced Thermoset

Material Notes: TRA-DUCT 2929 is recommended for electronic bonding, coating and sealing applications that require high flexibility coupled with excellent electrical and mechanical properties. This two-part epoxy adhesive develops resilient, electrically and thermally conducting bonds and coatings between materials such as metals, ceramics, glass and plastic insulates. TRA-DUCT 2929 cures at room temperature and can be used as a flexible "cold-solder" for heat sensitive components.
