Product Description

 SB-448 is a RTV 1-part neutral silicone sealant. It exhibits high thermal conductivity due to heavily filled with heat-conductive metal oxides. It exhibits good adhesion properties to most materials, such as transportation tools, boat, airplane, metals, glass, ceramics and electronic devices. At room temperature curing process, It does not generate heat neither corrosive by-product. It is very stable to wide changes of temperature. It helps to maintain a positive heat sink seal that improves heat transfer from the electrical/electronic devices to the heat sink or chassis, thereby increasing overall efficiency of the devices.


  1. Neutral, no corrosive by-product.
  2. Easy operation (premixing and heating are not required).
  3. Excellent adhesion properties for a variety of materials.
  4. Good thermal conductivity.
  5. Good waterproof and chemical resistance.
  6. Excellent dielectric properties and weather resistance.
  7. Wide service temperature range (-40oC ~ 200oC).
