8331D is an electrically conductive, 2-part silver epoxy adhesive. It is an improved version of our legendary silver-filled epoxy adhesive, 8331. It is smooth, non-sagging, thixotropic, and bonds well to a wide variety of substrates.

This electrically conductive silver epoxy allows for quick, cold-soldering repairs. It is considered a solder replacement epoxy for bonding heat-sensitive electronic components, or for making conductive connections where soldering is not an option, such as when bonding to glass, soft metals, or plastics. It provides excellent EMI/RFI shielding and is very effective in filling seams between metal plates.

This DIY conductive epoxy has been formulated to be economical. For a higher fill that maximizes conductivity, use 8330D. For a longer working time, use 8331S.

For a 1-part alternative use 9410 or 9400.

We also offer a full line of thermally conductive electrically insulating epoxy adhesives.

We are a distinguished Supplier of Silver Conductive Epoxy (8330S). The 8330S Silver Conductive Epoxy Adhesive is an electronic grade epoxy that combines a long working time and high conductivity with ease of use. It has a convenient 1-to-1 mix ratio and 45 hours pot life, which once mixed behaves essentially like a 1-part adhesive for the duration of a work shift. However, unlike 1-part adhesives that often require high heat (130170^oC), it will cure at 65^oC in less than 2 hours. The cured conductive adhesive bonds very well to most of the substrates used in electronic assemblies. It resists thermal and mechanical shocks and provides the low-resistivity needed for many operating conditions. The 8330S epoxy adhesive forms excellent high-conductivity seals, bonds, and traces for electronic devices in the automobile, aerospace, marine, communication, and industrial control.

Features :

• Excellent 0.0007 cm electrical resistivity and 1.75 W/(m·K) thermal conductivity
• Easy 1:1 mix ratio and long working time may be mixed once and then used as a 1-part epoxy for a four-hour production shift
• Optimal cure temperature of only 65^oC lower than most 1-part epoxies and suitable for use on heat sensitive components
• Stores and ships at room temperature no freezing or dry ice required
• Very long shelf life of at least two years even when stored at room temperature
• Strong water and chemical resistance to brine, acids, bases, and aliphatic hydrocarbons
• Room temperature cure is possible (96 hours)
• Excellent adhesion to most electronic substrates

Applications :

• The 8330S epoxy has many uses in the production, repair, and assembly of electronics in microelectronics and optoelectronics.
• It has been designed for the production environments as a replacement for one part silver conductive epoxy systems when high cure temperatures can potentially damage the heat-sensitive components or where frozen storage requirements or shelf life of one part epoxies are a concern.
• Like all conductive epoxies, it operates as a lead-free replacement for metal solder and it excels at bonding heat-sensitive electronic components.
• It also provides excellent EMI/RFI shielding and is very effective in filling seams between the metal plates.

Application Instructions : Follow the procedure below for best results. Heat cure is recommended to get the best possible conductivity.

To prepare 1:1 (A:B) epoxy Mixture :

• Remove cap or cover.
• Measure one part by volume of A.
• Measure one part by volume of B.
• Thoroughly mix the parts together with a stir stick until homogeneous.
• Apply to with an appropriate sized stick for the application area.

Note :

• Remember to recap the syringe or container promptly after use.
• Tip - Due to the high viscosity and abrasiveness of the silver filler, you may preheat part A and part B to increase the flow and improve air release.

To Heat Cure the 8330S Epoxy :

• Put in oven at 65^oC [149^oF] for 60 minutes or above. For optimum conductivity and faster cure, heat cure at temperatures up to 100^oC.
• Tip - Hair dryers are normally rated not to exceed 60^oC, so they can generally be used to accelerate the cure.
• You can cure the epoxy faster by using higher temperatures of up to 100^oC [212^oF].
•  Keep the curing temperature well below temperature limit of heat sensitive components that may be present. As a guideline, remember that commercial grade devices normally can be safely operated up to 70^oC, industrial grade up to 85^oC, and military grade up to 175^oC.
• Attention - Heat guns can easily exceed the temperature limits for your assembly: they should not be used.
• To room temperature cure the 8330S epoxy:
• Let it stand for 96 hours or more.
• Tip - While the product can be cured at room temperature, the best conductivity is achieved with the application of some heat.

Application Instructions :

• Follow the procedure below for best results. For mixing quantities that are less than 1 mL in size or for stricter stoichiometry control, mix by weight ratio instead (requires a high precision balance).
• Heat cure is recommended to get the best possible conductivity.

To prepare 1:1 (A:B) Mixture :

• Remove cap or cover.
• Measure one part by volume of A.
• Measure one part by volume of B.
• Thoroughly mix the parts together with a stir stick until homogeneous.
• Apply with an appropriate sized stick for the application area.

Note :

• Remember to recap the syringe or container promptly after use.

• Tip: Note that the material viscosity decreases with mixing, so the material will be most liquid-like and easily applied immediately after being mixed. Due to short cure time, apply as soon as possible after mixing.
• To heat cure the 8329TCF
• Put in oven at 65^oC [149^oF] for 15 minutes.
• Tip - Hair dryers are normally rated not to exceed 60^oC, so they can generally be used to accelerate the cure.
• Attention - Keep the curing temperature well below temperature limit of heat sensitive components that may be present. As a guideline, remember that commercial grade devices normally can be safely operated up to 70^oC, industrial grade up to 85^oC, and military grade up to 175^oC.
