U-POL S2045 is a high-quality, virgin-solvent universal thinner designed to adjust the spray viscosity of a wide range of automotive coating systems. Part of the System 20 range, this "Standard" speed formulation is the versatile "go-to" reducer for most bodyshop environments, offering a balanced evaporation rate that ensures optimal flow and leveling in moderate temperatures.
Key Performance Features:
- Multi-System Compatibility: Formulated for use with 2K clear coats, 2K solid colors, basecoats (metallic and pearl), and all U-POL primers.
- Virgin Solvent Purity: Unlike "recycled" thinners, S2045 is made from 100% virgin solvents, ensuring no moisture or contaminants interfere with the chemical curing of isocyanate hardeners.
- Balanced Evaporation: Specifically engineered for standard workshop temperatures, providing a consistent "open time" that prevents dry spray while ensuring a timely flash-off.
- Optimal Flow & Leveling: Reduces the viscosity of high-solids (HS) coatings to help achieve a smooth, orange-peel-free finish.
- Specialty Use with Raptor: Often used at up to 20% to thin Raptor Liner, allowing for a much finer, flatter texture than the standard coarse finish.
Expert Tip: If you are experiencing "solvent pop" (tiny bubbles in the clear coat), it is often because the thinner is evaporating too fast. In such cases, or if the shop gets warm during the day, you can mix S2045 with S2046 (Slow) to create a custom "Medium-Slow" blend that allows more time for the solvent to escape.
Safety Warning: This product is highly flammable and contains hazardous organic solvents (Xylene/Butyl Acetate). Professional use only. Ensure adequate ventilation and wear an A2P3 organic vapor mask and nitrile gloves during use.
