MG Chemicals 8330D-160G, Silver Conductive Epoxy Adhesive, 160g Jar Kit, Case of 1 Kit
MG Chemicals 8330D-160G, Silver Conductive Epoxy Adhesive, 160g Jar Kit, Case of 1 Kit
Made to order: This is one two-jar kit containing separate Parts A and B. Confirm current production lead time before planning your project.
MG Chemicals 8330D-160G is a silver-filled, two-part electrically conductive epoxy adhesive for permanent conductive bonding and cold-soldering repairs. The formulation is highly filled to maximize electrical conductivity, with a smooth, non-sagging, thixotropic consistency and adhesion to a wide variety of substrates. MG identifies 8330D as an improved version of its original 8330 formula.
Although the SKU uses “160G,” the manufacturer lists a combined net weight of 162 g and combined net volume of 50 mL. These are totals for the complete two-jar kit, not the amount in each jar.
Best Uses / Applications
- Cold-soldering repairs on electronic assemblies.
- Conductive bonding of heat-sensitive components where conventional soldering is unsuitable.
- Making electrical connections to qualified substrates such as glass, soft metals, and plastics.
- Filling seams between metal plates for EMI/RFI shielding applications.
- Repeated bench repair, prototyping, and assembly work requiring a larger kit than the syringe format.
Key Features
- Highly silver-filled formulation designed to maximize electrical conductivity.
- Combines mechanical bonding with permanent electrical connections.
- Smooth, non-sagging, thixotropic consistency.
- Room-temperature cure or accelerated heat cure.
- Manufacturer-listed resistance to humidity, salt water, mild bases, and aliphatic hydrocarbons.
- Excellent adhesion to many substrates.
- Room-temperature storage and long shelf life.
- Manufacturer identifies the formulation as SVHC free; consult current documentation for procurement requirements.
Technical Specifications
Values follow the manufacturer TDS dated May 19, 2026. Its working time is 25 minutes at 22°C, while the vendor webpage still displays 20 minutes. Confirm instructions applicable to your supplied batch when timing is critical.

Jar-Kit Preparation, Mixing & Cure
Read the kit SDS before use. The TDS recommends cleaning the substrate with isopropyl alcohol, MG 824, to remove oils, dust, and residues; confirm compatibility first. Stir each part separately to reincorporate material that may have separated. Measure 1.1 parts A to 1 part B by weight, mix thoroughly, and apply to the intended area. If measuring by volume instead, use 1:1. Equal weights are not the specified ratio.
Keep components separate until mixing and recap jars firmly after use. Choose a cure schedule compatible with the entire assembly. Set time and working time are not full cure. Qualify electrical, mechanical, and temperature performance before placing the assembly into service. Avoid spread onto adjacent conductors where conductive adhesive could cause shorts.
Format & Product Comparison
| Option | Distinction | Selection consideration |
|---|---|---|
| 8330D-160G | Made-to-order two-jar kit, 162 g / 50 mL | Larger quantity of 8330D; this listing |
| 8330D-19G | Two-syringe kit, 19.4 g / 6 mL | Smaller repairs and localized dispensing |
| 8331D | Economical conductive epoxy alternative | MG recommends it when economy is the priority; use its own specifications |
| 8330S | Different conductive epoxy formulation | MG recommends it for longer working time |
| Conductive paint | Coating rather than bonding adhesive | Broad-area shielding rather than adhesive seam filling |
Frequently Asked Questions
Is this still a complete kit?
Yes. This listing supplies one two-jar kit with separate Parts A and B, not a single premixed jar.
Why does the SKU say 160G when the net weight is 162 g?
8330D-160G is the manufacturer's part number. The current TDS and product page list 162 g and 50 mL as the combined kit contents.
Is each jar 162 g?
No. The stated weight and volume are totals for both parts combined.
Is this format made to order?
Yes. Confirm the current production lead time before planning work. No fixed lead time or immediate-stock claim is implied.
How do I mix the jar kit?
Stir each part separately, then measure 1.1 parts A to 1 part B by weight and mix thoroughly. The alternative volume ratio is 1:1.
Is working time 20 or 25 minutes?
The May 19, 2026 TDS lists 25 minutes at 22°C. The vendor webpage still lists 20 minutes. This page follows the dated TDS; check the applicable instructions for your supplied batch.
How long does it take to cure?
The listed schedules are 6 hours at room temperature, 10 minutes at 65°C, or 5 minutes at 80°C. The 40-minute set time at 22°C is not full cure.
Can it replace solder?
It can provide conductive bonding where soldering is unsuitable, including heat-sensitive components and certain non-solderable substrates. It is not automatically equivalent to a solder joint; qualify each application.
Is it electrically insulating?
No. It conducts electricity. Prevent unintended connections to nearby conductors, and choose an electrically insulating adhesive when isolation is required.
How should I store the jars?
Store at 16–27°C in a dry area away from sunlight, with lids firmly closed. The TDS lists a three-year shelf life under specified conditions.
