Uniweld Cool Blue™ Heat Sink Paste

The Uniweld Cool Blue™ Heat Sink Paste (Part #91861) is a specialized thermal paste designed to protect heat-sensitive components during soldering, brazing, or welding processes. This paste acts as a heat sink, absorbing excessive heat and preventing damage to adjacent materials such as rubber and plastic seals in ball valves, solenoid valves, reversing valves, and other heat-sensitive components.

A unique feature of this paste is its heat transfer color indicator. As the paste absorbs heat, it changes color from blue to dark blue, providing a visual cue to the technician that the material is effectively dissipating heat. This feature enhances safety and precision during high-temperature operations.

The paste is safe to use, non-toxic, odorless, and harmless to the skin. It is also easy to clean, requiring only a cloth wipe or a wash with water to remove any residue.
