Acetone Uses in the Autobody Industry
Acetone is a multi-use solvent that is generally considered safe for humans to use. The chemical is incorporated into paint supplies and cleaners used in the auto body painting and repair industry. Compounds used at every stage of the painting and cleaning process contain at least small amounts of acetone.
Cleaning Solution
Acetone is used in cleaning solutions applied to spray guns used in auto body work. The solvent is able to break down the harsh and potentially toxic chemicals used in auto body paints. Certain states, like California, are attempting to move away from sprays and solvents containing highly volatile organic compounds. According to a 2008 study prepared for the Cal/EPAs Toxic Substances Control, the best alternative cleaning solutions included a blend of glycol and acetone.
Finishing Solution
Finishing solutions are applied to auto body paint jobs to seal the paint and keep it from flaking or cracking due to weather or temperature conditions. These compounds typically contain acetone as an active ingredient that goes on clear so the cars paint job isnt obscured. In fact, acetone sealers usually add shine to the paint. The chemical is also used in window tints.
Paint Thinner
Auto body paints are combined with acetone to thin them. This allows the paint to apply evenly to the surface without pooling too much, which can affect drying times. The chemical dissolves when the paint is heated, leaving an even coat of paint. Acetone is also used as a pre-paint cleaner to remove any grit or surface grease on auto body parts that could affect the painting process and create dimples or raised areas.
