Typical components include:
- Toluene
- Acetone
- Methyl ethyl ketone (MEK)
- Methanol
- Xylene
- Ethyl acetate

How Lacquer Thinner Works
The solvents break down the resins in lacquer, making the paint thinner for spraying or brushing. They also dissolve dried lacquer for cleanup. The mixture evaporates fast, allowing quick drying.
Main Uses
