Applications & Uses

Major Application

Heat sink compound is applied to the base and mounting studs of transistors, diodes and silicone controlled rectifiers. In these situations, a small amount of thermal grease using either dispensing or screen printing/stencil is best. It has also been used as a high- voltage corona suppressant, non-flammable coating in connections for fly back transformers in TV sets and similar applications. It also used in mounting semiconductor devises; mounting power transistors and diodes; coupling entire heat generating assemblies to chassis; heat transfer medium on ballast; thermal joints; thermocouple wells; mounting power resistors; for any device where efficient cooling is required; major industries served include electronic (computer, appliance, wireless, etc.), automotive, electrical.

Clean Up

It is recommended that customer use disposable containers and utensils whenever possible to simplify clean up. However, when disposable containers are impractical, STG-51TC can be removed by cleaning equipments with such as Mineral spirit (Paint thinner), Hexane or Isopropyl alcohol. Observe appropriate precautions.
