Product Overview
CircuitWorks Heat Sink Grease (CT40-5) is a silicone-based thermal compound for heat transfer between components and heat sinks. The product is supplied in a 5 oz (142 g) tube and is described as a heavy-consistency compound thickened with a thermally conductive metal oxide filler to maintain intimate contact between the heat sink and the component.Features
- Non-corrosive
- Non-flammable
- High dielectric strength
- Low bleed
Typical Applications
- Used as a thermal coupler for heat sink devices (efficient heat transfer between device and heat sink) — as specified by the manufacturer.
- Used as a non-flammable surface protection in applications where the manufacturer specifies such use.
- Used for high-voltage corona protection, as stated in the manufacturer's technical data.
- Used for improving readings on contact-type thermocouples, according to manufacturer's information.
Application Instructions
The product is ready-to-use and supplied in a collapsible tube. According to the manufacturer's instructions, it is applied to mounting and threaded surfaces between the device and the chassis. The tube can be squeezed manually or with mechanical wringers. Refer to the manufacturer's technical documentation for more details.
