Three Bond 2285D - 1K Epoxidharz - 1 kg Dose

Overview of Three Bond 2285D epoxy resin

The Three Bond 2285D is a 1K epoxy resin for potting and bonding in electronics. As a Beige epoxy resin system it belongs to the category epoxy adhesives and impresses with high temperature and chemical resistance. The 1K system enables easy application, since no mixing ratio is required and dosing units can be automated.

Key values: Viscosity at 25 °C 146 Pa·s, Density at 25 °C 1.55 g/cm³, Tg 178 °C, Shelf life 6 months, Shear strength 27 MPa. The bond provides robust adhesion and reliably protects components from temperature stress and chemical exposure.

Main component is epoxy resin, the color of the resin is Beige. The combination of Tg, viscosity and density makes the product versatile, especially where electronics potting and permanent bonding are required.

Applications in electronics and potting

Electronic potting

Due to the high Tg and chemical resistance, the resin is ideal for potting PCBs, components, and housings in demanding environments. The high strength helps reduce cracking and loosening under temperature shocks.

Adhesive bonds in electronic components

As an adhesive, the epoxy resin provides durable bonds between components, substrates and housings. The bond remains reliable even with temperature changes, which increases reliability in final assembly.
