Paint Solvent

A paint solvent is a solution that has the ability to dissolve and dilute a solvent base paint. There are a variety of solvents, each compatible with a particular type of paint product including oil base paints and varnishes, lacquers, shellacs, and two part epoxies and conversion varnishes.

Paint Thinner, Mineral Spirits

Paint thinner and mineral spirits are petroleum based solvents used to thin or reduce the viscosity of oil base primers, paints, enamels, and varnishes. They are also used to clean tools and equipment used in conjunction with oil base paint products. Some paint thinners consist of 100% mineral spirits while some paint thinner products may contain additional additives. For the purposes of house painting, paint thinner and mineral spirits are interchangeable.

Paint thinner and mineral spirits are somewhat mild solvents that will not usually damage underlying paint coatings. Their evaporation rate is relatively slow compared to many other solvents. Paint thinner and mineral spirits are flammable liquids. Follow proper safety precautions when using these products.

VM&P Naptha Thinner

VM&P (Varnish Maker & Painter) Naptha thinner is petroleum based paint  solvent well suited to thin or reduce the viscosity of oil base primers, paints, enamels, and varnishes as well as to clean tools and equipment used together with oil base paint products. It can be used as an alternative for paint thinner or mineral spirits, where a faster drying time is desired. Its greater volatility and faster evaporation rate make Naptha thinner a good choice for spray painting applications.

VM&P Naptha thinner is a highly flammable liquid and should be handled with care. Follow proper safety precautions when using this product.

Lacquer Thinner

Lacquer thinner is a petroleum based blend of solvents primarily used in conjunction with lacquer products. Lacquer thinner is used to thin nitrocellulose, CAB-Acrylic, and catalyzed lacquers. It also can be used to clean tools and equipment used to apply lacquers.

Although lacquer thinner evaporates at a relatively fast rate, there is not a standard evaporation rate for all lacquer thinners. The composition of solvents that manufacturers use to produce lacquer thinners allows them to control the evaporation rates. There are two basic types of lacquer thinner used in the house painting / wood finishing industry, standard and slow. A slow thinner is a blend of lacquer thinner and lacquer retarder, formulated to be used in hot and/or humid conditions. In hot weather conditions a slower lacquer thinner with a slower evaporation rate, allows the lacquer to properly level out before it dries. In humid conditions a slower evaporation rate is less likely to trap moisture which will cause a blushing effect.

Lacquer thinner is a strong solvent that can attack and damage many types of underlying paint coatings. Lacquers should only be used over compatible coatings. Because lacquer thinner has a low flash point and is highly flammable, it should be handled with care. Follow proper safety precautions when using this product.

Acetone (paint solvent for two part paints)

Acetone is an organic compound that works well as a paint solvent for thinning and clean-up of two-part paint products such as catalyzed epoxies and conversion varnishes. Always check manufacturer's specifications before using acetone as a reducer for two-part paint products.

Some characteristics of acetone include its ability to evaporate quickly and dissolve in water. It also has a low flash point and is extremely flammable. Follow proper safety precautions when using this product.

Denatured Alcohol

Denatured alcohol is fundamentally ethanol with a variety of additives. The term “denatured” means that the alcohol has been made undrinkable with the addition of toxic chemicals. Denatured alcohol is used in the painting industry as a paint solvent to thin and clean-up shellac base paints and some aniline dye stains. It can also be used as a brush cleaner to remove dried latex paint. It is useful while sanding wood, to wipe away excess sanding dust from the wood surface, because it evaporates quickly and does not leave any residue. Denatured alcohol is flammable and should be handled with care.
