A paint thinner is a solvent
used to thin oil-based paint
s or clean up after their use. Commercially, solvents labeled "Paint Thinner" are usually mineral spirit
s having a flash point
at about 40 °C (104 °F), the same as some popular brands of charcoal starter.
Common solvents historically used as paint thinners include:
* Mineral spirits
(US) / White spirit
* Methyl ethyl ketone
, or any of the other glycol ethers
Less common solvents used as paint thinner include:THINNER 219 MSDS
* ''n''-Butyl acetate
Exposure to vapors created by paint containing thinner or its clean up may be hazardous. The American Conference of Governmental Industrial Hygienists has established threshold limit values (TLVs) for most of these compounds. TLV is defined as the maximum concentration in air which can be breathed by a normal person (i.e., excluding children, pregnant women, etc.) in the course of 40 hours per week (a typical American work week), day after day through their work life without long-term ill effects.
In underdeveloped countries workers commonly experience much higher exposure to these chemicals with consequent damage to their health.
