Description of silicone glue for electronics

SATOP®8739 is a Dealcohol type neutral silicone sealant that absorbs moisture from air at room temperature.It has good adhesion sealing property to most materials, to protect electronic products under stringent conditions.


Elastomer of SATOP®8739 has the following characteristics: 

  1. Excellent chemical resistance, low odor, good adhesion.
  2. Low volatiles of no more than 500ppm, airtight environment no corrosion no fog.
  3. Reduce mechanical stress and tension caused by mechanical, thermal shock and vibration.
  4. Excellent electrical insulation, anti – corona silicone glue for electronics
  5. Excellent outdoor aging, service life can reach 20 to 30 years
  6. stable mechanical and electrical propertiesbetween 60 to 260 ℃

Operation process of silicone glue for electronics

  1. Cleaning surface: cleansurface, remove rust, dust and oil.No need bottom coating to most material, such as glass, metal and most commonly industrial plastics.But on some polymers, it may be less cohesive.For example: polyethylene, polypropylene and PTFE, use PM1200 to do bottom coating.
  2. cut the nozzle to the required size, Fitted with glue gun, squeeze the glue into the cleaned surface and distribute evenly, When bonding, fixed two surface together. Under the conditions of room temperature and 55% relative humidity, adhesive’s surface dry in about 15 minutes, therefore, all processing must be completed before surface dry.
  3. Cured:Cured: place the coated parts in the air and used them after curing for 24 hours at room temperature.
  4. Precautions: after opening SATOP®8739, use it as soon as possible, once again, when used again, squeeze out the solidified part, continue to use, do not affect normal use.
  5. please consult the market departmentif use dispensing equipment

Precautions of silicone glue for electronics

  1. Keep away from children
  2. It is recommended to be used in well-ventilated places.
  3. Wash the skin with soapy water immediately if it touches the skin carelessly.
  4. If you touch your eyes accidentally, rinse immediately with water for a long time and open your eyes. If irritation persists, seek medical attention.
