SANDAO newly rtv silicone rubber producer for screws-1
Economical heat conductive silicone grease SD3801
Economical heat conductive silicone grease SD3801 is one component with medium thermal conductivity, which is made from imported silicone as the main body, filling materials, thermal conductive materials and other polymer materials. It’s compound of organosiloxane and metal oxides which with good thermal conductivity and insulation. This grease has excellent thermal conductivity, no curing, no powdering, high temperature resistance, low adhesion pressure, oxidation resistance, no air drying hardening or melting, low thermal resistance, good electrical insulation, Wide operating temperature (-50 ℃ ~ 200 ℃), good stability, low consistency and good operation performance. The silicone grease is non-toxic, non-corrosive, tasteless, never curing and insoluble.



Heat conductive silicone grease is widely used to fill the gap between power heating element and radiator, especially high power LED heat dissipation or coating, to derive the heat produced by components. Such as CPU and radiator gap filling, high-power transistor, thyristor element, diode and substrate (aluminum, copper) converter, power module, oven, induction cooker, coffee pot gap filling, TV power amplifier tube and heat sink, Semiconductor refrigeration, etc. Reduce the working temperature of the heating element.

Use instructions


  • Clean the surface, remove the greasy dirt, then extrude thermal conductive silicon grease directly.

  • The uniform coating should be applied to the surface. The coating can be brushed, scraped or rolled as needed.

  • If the user uses silicone oil to dilute, not only occur oil separation easily, but also make the thermal conductivity smaller. Therefore, we suggest customers choose their ideal models to ensure the using quality.


  •    The coating surface should be uniform, coating more isn’t mean the better, but in the premise of filling the surface gap, coating a thin layer is enough.

Packaging and preservation


Packing specification: 1.0kg/ can, negotiable to according to the user's needs.  

Storage: store in a cool and dry place for one year.
