Product Description

Butanone is an effective and common solvent and is used in processes involving gumsresinscellulose acetate and nitrocellulose coatings and in vinyl films. For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquervarnishes, paint remover, a denaturing agent for denatured alcoholglues, and as a cleaning agent. It has similar solvent properties to acetone but boils at a higher temperature and has a significantly slower evaporation rate. Unlike acetone, it forms an azeotrope with water,making it useful for azeotropic distillation of moisture in certain applications. Butanone is also used in dry erase markersas the solvent of the erasable dye.
