Three Bond 3380B - 2K Leit-Epoxid - 300 g Set

2K Conductive Epoxy Three Bond 3380B at a Glance

The Three Bond 3380B is an electrically conductive two-component adhesive system based on epoxy resin with silver content. The material is available in the set as a 300 g total assembly, which is particularly suitable for temperature-sensitive components. The bond provides robust adhesion to metals and is characterized by very low outgassing as well as chemical and thermal resistance. The mix ratio is 2:1 (resin : hardener). The viscosity of resin is approx. 31 Pa·s, hardener approx. 2.9 Pa·s, and the pot life is about 90 minutes at 25 °C. The curing is chemically/thermally resistant and the adhesive remains stable under temperature loadings. The base color is silver; main component epoxy + silver.

Suitable for temperature-sensitive components and conductive connections

The 2K system connects temperature-sensitive components, while the silver components ensure electrical conductivity. Therefore applications are suited for areas where isolation and simultaneous connectivity are required.

Electrically conductive and robust

The silver component ensures reliable electrical conductivity, while the epoxy resin provides a mechanically robust structure. The combination is designed to keep metal joints resistant even under heat and to enable a durable bond.

Processing & Practice

1. Mix resin and hardener in a 2:1 ratio carefully until a homogeneous mass forms.
2. Apply to the prepared bonding surface and ensure uniformity to avoid air bubbles.
3. Depending on requirements, cure; the pot life is approx. 90 minutes at 25 °C.
4. Note final strength after complete curing and gradually increase temperature exposure.

Structure: Epoxy Resin + Silver

The system is based on an epoxy resin that is refined with silver particles. This material choice ensures, in addition to tribological stability, a conductive connection, ideal for temperature-sensitive electronic components.
