This compound silicone paste from Jelt is a 1-piece oil and metal oxide based silicone adhesive, ideal for the thermal coupling of electrical and electronic components, or between any surface where thermal conductivity or heat dissipation is vital. The excellent thermal conductivity properties ensure that the adhesive can facilitate heat transfer between components, preventing failure and overheating. This compound silicone offers a wide operating temperature range of -50°C to +250°C, providing a versatile adhesive that can be used in a range of applications.

• Wide operating range of -50°C to +250°C, making it ideal for use with a variety of applications
• Excellent thermal conductivity even at high temperatures
• Thermal conductivity of 0.41 W / mK
• Effectively protects terminals from mechanical and thermal impacts, and moisture
• Perfect for protecting electrical circuits

Thermal adhesives are a type of thermally conductive adhesive used to secure heat sinks and electronic components. Thermal adhesives are available in a number of mediums such as thermal paste, glue, tape and more. They work by creating a strong bond for heatsinks or electrical parts commonly via a two-part epoxy resin with thermal conductivity capabilities, drawing heat away from a device. Thermal adhesives are used in a variety of industries and applications such as:

• Heat sink bonding
• Potting/encapsulating sensors
• BGA die heat spreader interface
• Chip scale packages
• Power semiconductors

Before applying, ensure surfaces are clean and free from grease, dust and contaminants. Apply a thin layer of the adhesive paste to the components to be bonded, leaving the product untouched during the curing process.

Thermal adhesives such as grease and pastes can be removed if required using a combination of a thermal adhesive remover (or high concentrate rubbing alcohol) and a lint free micro fibre cloth. Please note special care must be taken when removing thermal compounds and protective clothing must be worn at all times.

The maximum operating temperature of this thermally conductive sealant is +250°C.
