Abstract
A formable, weldable, VOC-free protective coating for use on a number of substrates including metal, wood, concrete, plastic, pipe and transportation equipment. The composition includes beeswax, ammonia, water and, optionally, paraffin. It may also include fillers, dyes, pigments and corrosion inhibitors, but does not require surfactants or stabilizers. The composition is particularly useful for protecting steel prior to welding. It can be removed without organic solvents.
