MG Chemicals 8331D-14G, Silver Conductive Epoxy Adhesive, 14g Syringe Kit, Case of 1 Kit
MG Chemicals 8331D-14G Silver Conductive Epoxy Adhesive, 14g Syringe Kit
MG Chemicals 8331D is an electrically conductive 2-part silver epoxy adhesive — an improved version of the legendary 8331. Smooth, non-sagging, and thixotropic, it bonds well to a wide variety of substrates and enables quick cold-soldering repairs. Ideal as a solder replacement for heat-sensitive electronic components or for making conductive connections where soldering is not an option, such as bonding to glass, soft metals, or plastics. Provides excellent EMI/RFI shielding and is very effective for filling seams between metal plates.

Frequently Asked Questions
What is the difference between 8331D and the original 8331?
8331D is an improved version of MG Chemicals' original 8331 silver conductive epoxy. It offers the same high electrical conductivity and broad substrate adhesion with improved formulation characteristics including smoother consistency and non-sagging thixotropic behavior.
Can 8331D replace solder?
Yes — 8331D is specifically designed as a solder replacement for situations where soldering is not possible or would damage heat-sensitive components. It creates strong, permanent electrical connections on substrates including glass, soft metals, and plastics.
How long does 8331D take to cure?
8331D cures in 6 hours at room temperature, or in 10 minutes at 65°C (149°F) for accelerated processing. Full properties are reached after complete cure.
Does 8331D require refrigerated storage?
No — 8331D can be stored at room temperature, making it convenient for bench-top use without special storage requirements.
