TIG780-45 — Product overview
TIG™780-45 is an environmentally safe silicone-based thermal grease engineered to solve overheating and reliability issues in electronic assemblies. The paste-form heat-conducting compound moistens the contact surface sufficiently to form an interface of extremely low thermal impedance, providing heat-dissipation efficiency far superior to many competing greases.
TIG780-45 — Features
Low thermal impedance
Non-toxic and environmentally safe
Excellent long-term stability
