Waxes and wax compounds are organic materials with high molecular weight, similar to fats and oils; however, waxes are solid at room temperature with a minimum melting point above 45° C (113° Fahrenheit). Waxes and wax compounds are used in sealers, polishes, coating, inks, adhesives, lubricants, binders, candles and candle making, investment casting patterns, and food additives. The most common use for waxes and wax compounds in the industrial and commercial industries is impregnation, a process used to protect products against water, water vapor, and corrosion. Impregnating wax is usually less viscous and melts at lower temperatures than most other waxes; thus, it has better penetration properties on porous materials.
