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 10:1 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 120°C. If cured under room temperature, about 8 hours.

  4. The adhesive force cured at room temperature is weak; the adhesive force cured at 80°C is slightly better; in order to obtain a good bonding effect, it is recommended that the heating temperature should not be lower than 100°C, preferably above 120°C.

  5. Recommended curing conditions: 100℃ for 1 hour.

  6. Please test the bonding of the substrate before use.

  7. Vacuum defoaming can improve the performance of cured product.

  8. Seal the remaining products tightly after use.

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

  10. It's hard for SI8295 to cure if contact with sulfur, amine, organotin and unsaturated hydrocarbon plasticizer. Common substances like rosin, natural rubber. For these should do test before application.

∎Remark

THERMAL POTTING COMPOUND

High thermal conductivity potting compound is used to create a protective barrier around high-heat electrical appliances, components, and motors to prevent overheating. Thermal potting compounds are also used for potting electrical circuits and filling voids to protect fragile components from corrosive agents, water, moisture, vibration, shock, and chemicals.

High thermal conductivity potting compounds are used for a variety of high-temperature applications. Electronics potting and encapsulating compounds by Maxtech are formulated for consistent material performance, with excellent dielectric properties, electrical insulation resistance, thermal conductivity, thermal shock resistance, mechanical strength, adhesion, hardness, cure speed, and chemical resistance.

High thermal potting compounds for electrical equipment that may generate a lot of heat. For example, motors can overheat and cause damage to the rest of an electrical or mechanical device. Thermal potting compounds have a wide operating temperature range, which can prevent motors from overheating.
