How it Works
HyloCool is an aqueous gel that adheres to horizontal and vertical surfaces, even when heated, and absorbs heat. HyloCool Thermal Barrier Gel works by trapping water on the surface of the substrate. Its additives and surfactants reduce the boiling point of the water, increase the surface area in contact with the metal, and hold the gel in place. The phase change from liquid to gas absorbs the heat as evaporative cooling. Under high or sustained heat HyloCool will evaporate, leaving a minimal amount of residue behind.
Instructions for Use
For welding: put a bead of HyloCool around the object being heated and the gel will inhibit heat transfer. The size of the bead required will depend on the heat source, duration, and thickness and thermal conductivity of the object. HyloCool is not a substitute for safety equipment. Use proper and sensible protective equipment, including gloves and eyewear, when welding. Reapplication may be necessary, particularly on vertical surfaces.
As a masking compound: Spread a layer of HyloCool over the area exposed to heat. Thicker layers will provide more protection. Horizontal surfaces will be protected longer. Re-application may be necessary.
Clean up: HyloCool will wash off with water, or with a moist towel. Any baked-on residue can be removed with light abrasion, such as with steel wool.
Storage: HyloCool must be kept from freezing, as the thixotropic gel will loose its cohesion and collapse.
