PPG Thinner AT911 – Slow-Evaporating Acrylic Reducer for Demanding Conditions

Engineered for Warm Weather and Extended Pot Life Applications

Optimized for Spray, Brush, and Roll – 1 Gallon

PPG Thinner AT911 is a slow-evaporating acrylic solvent designed to maintain workability and extend pot life in warm, dry, or high-temperature environments. When fast-evaporating thinners cause premature drying, orange peel, or application issues, AT911 gives you the open time needed to achieve a smooth, professional finish without rushing the job.

Compatible with PPG acrylic topcoat and basecoat systems, AT911 is the preferred reducer when ambient conditions demand a slower solvent — keeping your coating flowing correctly from first pass to final coat.

• Extended pot life — slows evaporation rate to maintain workability in hot or dry conditions
• Improved flow & leveling — reduces orange peel and surface defects caused by rapid solvent flash-off
• Temperature-optimized — formulated for use in warm ambient conditions where standard thinners fall short
• Viscosity control — fine-tune coating consistency for spray, brush, or roll application
• Compatible with PPG acrylic systems — works seamlessly with PPG acrylic topcoats and basecoats
• Proper film build — supports target dry film thickness and uniform coating appearance
• 1-gallon format — right-sized for single-job or smaller-scale coating applications
