THERMALLY CONDUCTIVE SILICONE AND

ELECTRICAL INSULATOR - GT 907

GT 907 is an RTV polyaddition silicone elastomer, fluid and curing at room
temperature with no solvent requirements. When vulcanised it has
good thermal conductivity and flame-resistance (UL 94 V0).

• Recommended for encapsulating and
coating electrical and components.
• It can be used and an electrically sealing
thermal drain
• This product’s continuous working
temperature is from -50°C to +220°C
