Hi-Heat Soldering Investment Powder, 4.5 lb Package

Hi-Heat Soldering Investment is a gypsum-bound investment ideal for soldering with an oxygen-gas torch, providing a fine and smooth surface. It is excellent for high-fusing ceramic alloys in pre- and post-soldering techniques, and can also be used for soldering precision attachments. The powder flows freely into small crevices, stacks and molds easily, sets moderately fast, trims smoothly, and withstands rapid drying.
