Two parts thermal conductive potting silicone for electronics SI2230

 

SI2230 is two-component silicone based thermal conductive potting encapsulant. It has a good fluidity after mixing, can vulcanize to 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 standard.

 

Usage

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.

Direction for 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 cured product.

 2). Seal the remaining products tightly after use.

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