## Overview

MG Chemicals 8331S is a two-part silver-filled epoxy adhesive designed for high conductivity and extended working time. It cures at low heat (65°C) over 2 hours, making it perfect for bonding sensitive electronic components while providing robust EMI/RFI shielding. With an ultra-low electrical resistivity of 0.006 Ω·cm and thermal stability from -40°C to 150°C, it ensures durable, reliable connections in demanding environments. RoHS and REACH compliant, this 15g kit includes two dispensers and mixes 1:1 at room temperature, offering professional-grade performance without the hassle.

## Description

The MG Chemicals 8331S is a two-part silver-filled epoxy adhesive with good conductivity and a longer working time than MG Chemicals 8331 adhesive to bond electronic devices, form conductivity seals, and cold solder heat-sensitive materials. It cures at low temperatures to avoid damage to electronic equipment and bonds well to most materials used in such devices. It also provides protection against electromagnetic (EMI) and radio frequency (RFI) interference. The epoxy adhesive resists water, brine, acids, bases, and aliphatic hydrocarbons, and cures to a silver beige colour. It is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization of Chemicals) compliant.

### ⭐⭐⭐⭐⭐ Review
*by J***E on 25 November 2024*

Fixed an expensive LiFePo4 battery that had a bad spot welded aluminum terminal. Tapped some small shallow holes in the top of the aluminum disc to give it something go look into, and epoxied the terminal back on. Holds like a weld.
