Whip Mix Hi-Heat Soldering Investment, 4.5 lb, 01546

Whip Mix Hi-Heat Soldering Investment is a gypsum-bound, multi-purpose soldering investment ideal for oxygen-gas torch soldering and high-fusing ceramic alloys, including chrome-cobalt. Its fine texture mixes readily with water to a smooth, stackable consistency that flows into the smallest crevices, sets moderately fast, and withstands rapid drying or boiling-water flushing. The high-strength, heat-shock-resistant material trims smoothly and devests easily, with a 2-4 minute working time, 20-minute minimum dewaxing time, and 0.20% setting expansion.
