LA-CO Cool Gel® Heat Barrier Spray creates a protective barrier that helps prevent heat damage to components and finished surrounding materials during soldering, brazing, and welding operations. The thick gel formula sticks to surfaces without running or dripping, keeping protection exactly where you apply it.
After use, Cool Gel® evaporates cleanly within 24–48 hours, leaving no stain or residue and eliminating the need for cleanup. The formula is non-toxic and contains no asbestos, making it a safe choice for professional and DIY applications.
