Maxtech SI8230  Two-component thermally conductive flame retardant silicone potting compound glue for electronic

∎Product Description

SI8230 is two-component silicone-based thermal conductive potting adhesive. It has a good fluidity after mixing, can vulcanize to a deep layer in room temperature. The operation time can be adjusted according to the temperature. Used to potting protection of varied heat dissipation and temperature resistance components. Fully compliant with RoHS and SVHC REACH standards.

​

∎Key Features

​

  1. Two-part 1:1 mixture addition type silicone adhesive

  2. Low hardening shrinkage

  3. Excellent electrical insulation in high temperature and stability

  4. Good waterproof and moisture resistance 

  5. Excellent flame-resistance, UL No: E340199

​

∎Typical Applications

●Used for encapsulation of various modules, automotive module, LED Power driver modules, Solar panel junction box, EV charging column module, Lithium battery pack, Capacitor banks, Magnetic induction coils, Power inverters, etc.

How to use ?
​

  1. Mixing uniformity in the packing before using, as there’s part of filler sedimentation happens during storage.

  2. Mix Part A and Part B by 1:1 mass ratio, after evenly mixed, pouring directly into the components or modules as per requirements. It’s recommended to slowly pour along the walls of the implements, so as to reduce the bubbles happens.

  3. Still the potted component to let out the bubbles. Can be cured by heat, about 30 minutes in 80°C. If cured under room temperature, about 4 hours.

  1. Vacuum defoaming can improve the performance of the cured products.

  2. Seal the remaining products tightly after use.

  3. The low temperature will slow the curing speed, overheating will lead to curing speed too fast. Keep a constant temperature in the workshop is recommended.

  4. It's hard for SI8230 to cure if contact with sulfur, amine, organotin, and unsaturated hydrocarbon plasticizer. Common substances like rosin, natural rubber. For these should do a test before application.
