Heat Shield Heat Blocking Compound

Using a wet rag to stop heat travelling when brazing, soldering and welding is the traditional method of protecting heat sensitive areas around a welding site. However, a wet rag can be awkward to position, can dry out and needs to be kept wet. Proven to block conductive heat transfer, Heat Shield putty protects pipes, surfaces and sensitive areas from heat damage. Simply apply the Heat Shield putty to the area that needs protecting; braze, solder or weld, allow to cool, peel off, remould and reuse. No more need for messy wet rags! Time saving, non-toxic and with a no-mess formula, Heat Shield is the perfect product for combating conductive heat transference.
