Standard Thinner
Standard Thinner is a solvent blend designed to reduce the viscosity of paints, varnishes, and coatings to facilitate easier application and improved finish. Typically composed of organic solvents such as mineral spirits, toluene, or xylene, this product aids in controlling drying time and enhancing flow properties. Packaged typically in liquid form, it is compatible with various paint systems including alkyd, nitrocellulose, and synthetic coatings.
Uses
Primary Uses
Paints & Coatings
- Viscosity Reduction: Thins paints and varnishes for better spray or brush application.
- Flow Improvement: Enhances leveling and uniformity of coatings.
- Drying Control: Modifies drying rate to prevent defects like sagging or orange peel.
Industrial Applications
- Cleaning Agent: Cleans spray guns, brushes, and equipment contaminated with paints or adhesives.
- Diluent: Used in manufacturing processes to adjust formulation consistency.
Automotive
- Body Shop: Used to thin automotive paints and clear coats for refinishing work.
Secondary Uses
Adhesives & Sealants
- Viscosity Adjuster: Adjusts flow characteristics of certain adhesive formulations.
Printing Industry
Ink Thinner: Reduces viscosity of solvent-based printing inks for improved application.
