1. Product Introduction & Main Application
Arnico’s White Spirit Thinner is a clear, colorless aliphatic hydrocarbon solvent with a mild petroleum odor, obtained from the precise distillation of selected light crude oil fractions. This mild and economical solvent is the gold standard for thinning and adjusting the viscosity of architectural oil-based and alkyd paints, cleaning paint brushes and rollers, and industrial metal degreasing.

3. Features & Benefits
-
Balanced Thinning Power: Reduces paint viscosity without attacking the primer or causing runs and gloss loss.
-
Odorless & Safe (Premium): Eliminates the strong, unpleasant odor and reduces toxicity for use in confined spaces, hospitals, and homes.
-
Controlled Volatility: The ideal drying time allows the paint to spread and level beautifully on the surface (Leveling).
-
Very Low Corrosivity: Does not cause rust or corrosion in metal tanks and painting equipment.
4. Industrial Applications
-
Paint & Coatings Industry: The primary thinner for oil-based, alkyd, and architectural primers.
-
Cleaners: A cleaner for paint brushes, rollers, painting equipment, and a metal parts degreaser.
-
Waxes & Polishes: A carrier in floor wax, furniture polish, and car wax.
-
Printing Industry: A base solvent for letterpress and web offset inks.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This liquid is flammable and an irritant. Its vapors are narcotic and toxic at high concentrations. The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in sealed tanks with a breather valve, in a cool, dry environment, away from heat, direct light, and sparks.
-
Personal Protective Equipment (PPE): Chemical-resistant gloves, safety goggles, and, if ventilation is insufficient, a respirator with an A-type filter are required.
