About Paint and Protective Coatings

Avoid the fumes and strong smell of traditional thinners with these odorless thinners. They're often used for cleanup and to thin paint for spray applications. They cannot be sold to the regions listed due to product labeling requirements and/or local regulatory limits on VOCs (volatile organic compounds).

Low-Odor Thinners

These thinners are acetone and naphtha based, so they're low odor. They're often used for cleanup and to thin paint for spray applications. They cannot be sold outside the United States due to product labeling requirements.

Epoxy Thinners

Dilute thick epoxies so they're thin enough to spray. These thinners evaporate quickly enough that sprayed coatings won't sag, but slowly enough that they still bond well. They cannot be sold to the regions listed due to local regulatory limits on VOCs (volatile organic compounds).

Thinners for Water-Based Paint and Coatings

Smooth-Finish Paint Additives

These additives slow down paint’s cure time, allowing it to flow better and fill in brushstrokes for a smooth finish. They also improve adhesion.

Use water-based additives with water-based paint, such as latex and acrylic paint. One quart treats up to four gallons of paint.

Use solvent-based additives with oil- and solvent-based paint. One quart treats up to two gallons of paint.

Chemicals

Also known as technical-grade chemicals, these industrial-grade chemicals are not suitable for food or medicinal use.

Chemicals that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds), greenhouse gas emissions, and/or fall under DEA (Drug Enforcement Agency) or local import regulations.
