Description of silicone adhesive 

SATOP®8716,8717 is a Dealcohol type neutral silicone adhesive that absorbs moisture from air at room temperature.thermal conductive silicone sealant of add special thermal conductive material, After curing, formed flexible rubber, compliance with EU ROHS directive. releases alcohol in curing process. No corrosion to polycarbonate (PC), copper and other materials, Good adhesion and sealing performance to most materials, Protect electronic products under stringent conditions.


Elastomer of SATOP®8716, 8717 silicone adhesive has the following characteristics:

  1. Higher thermal conductivity
  2. After curing, adhesive tape is not yellow and oil, and comprehensive performance is excellent
  3. Anti – moisture, pollution and other atmosphere components
  4. Reduce mechanical stress and tension caused by mechanical, thermal shock and vibration
  5. Excellent electrical insulation, anti – corona
  6. Excellent outdoor aging, service life can reach 20 to 30 years
  7. Stable mechanical and electrical properties between 60 to 260 ℃

Storage and transportation

  1. Avoid light, heat.
  2. This product is non-dangerous goods and is transported it according to general chemicals.
  3. Shelf life is 12 months under 25 ℃. Please take a sample testif more than the storage.

Operation process 

  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®8716, 8717, 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.



  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.
