SS-35 Product Description
Download PDF
SS-35 is a thermally conductive silicone RTV adhesive rubber developed for
heat sink applications. SS-35 is a 1-Part silicone that when applied to the
substrate enables adhesion to parts and heat transfer of the bonded assembly
within minutes. When cured, the elastomer resists weathering, ozone, moisture,
UV and high temperatures. SS-35 works well in manual and automatic dispensing
equipment.
