Gap Filler Liquids - MH&W Thermal Products

Ceramic-filled two-component silicone elastomers offer a new and unique way to apply thermal interface materials without any stress on the covered components.  The possible application with hand held tools or automatic dispensing equipment allows the use in small and large production volumes. In addition, the curing at room temperature allows for “Wet-in-wet” production of even the most delicate components.

Customer specific solutions for the compound technology and processing technology is our strength. Kerafol has worked with the manufacturers of modern dispensing technologies allowing the application of heat conducting material onto the most diverse heat sinks or custom-specific components. Just Contact Us and we will be happy to help you in finding a solution.

Available in 50ml syringes, larger cartridges and cans.
