Talc welder's chalk

Welder's chalk - used on metal surfaces during welding and installation work, the manufacture of metal structures, metal cutting and other types of metalworking. Marking is not blown away by flame and does not burn out while working with oxygen cutting torches. The chalk has a high acid resistance, therefore it decomposes entirely only in hydrofluoric (hydrofluoric) acid HF.

The welder's chalk is moisture resistant and wear resistant, just like a metal marker leaves clear and thin marking lines. The peculiarity of the universal chalk is that it is simply indispensable when working on hot, wet or contaminated surfaces. It has low electrical and thermal conductivity. Widely used for marking before welding or cutting. Sold in a pack of 144 pieces.
