Product Details

Electrolube Thermally Conductive Ethoxy

Introducing the thermally conductive ethoxy adhesive from Electrolube, a single component low odour RTV (room temperature vulcanising) adhesive, ideal for bonding electrical components and heatsinks. This thermally conductive ethoxy has been designed to fill the gap between device and heat sink, reducing the thermal resistance. This reliable adhesive is perfect for dissipating excess heat from components and power resistors to heatsinks, preventing potential overheating or failures. The Electrolube ethoxy adhesive combines the properties of silicone rubber pads with those of a conventional heat transfer paste. This adhesive features a low bond strength, making it ideal for lightweight applications that may need to be removed in the future.

This single component ethoxy adhesive is perfect for use with the Electrolube application gun: 725-9984

Features and benefits

• Wide operating range of -50°C to +230°C, making it ideal for use with a variety of applications
• Excellent thermal conductivity even at high temperatures
• Thermal conductivity of 1.8W/mK
• Low viscosity for ease of application
• Good chemical resistance, helping to maintain strength
• Room temperature curing that is quick and easy to apply
• Low bond strength to allow for easy secure bond that can be removed if required


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

How to apply

Before applying, ensure surfaces are clean and free from grease, dust and contaminants. Insert the adhesive tube into the Electrolube application gun (stock no: 725-9984), which dispenses the product, providing efficient and accurate dispensing. The Electrolube thermally conductive ethoxy is a moisture curing system that releases ethanol upon cure. In order to achieve maximum cure potential, humidity above 50% is recommended. Elevated temperatures will not increase the curing process and is to be avoided.

Note: As this is a low bond strength adhesive, it is ideal for applications where later removal may be required and should not be used in heavy duty applications

Can this thermal adhesive be removed?

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.

What is the maximum operating temperature?

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