Характеристики

Ключевые свойства и преимущества

Superior Solvency: Exhibits high solvency for a broad spectrum of resins, including acrylics, epoxies, alkyds, and nitrocellulose.
Coupling Efficiency: Acts as an effective co-solvent, promoting miscibility between water and organic solvents in stabilized emulsions.
Optimal Evaporation Rate: Provides a mid-to-slow evaporation profile that extends «open time,» preventing premature drying and ensuring smooth finishes.
Low Odor Profile: Features a mild, non-intrusive scent, making it ideal for use in confined spaces or consumer-facing products.
Enhanced Safety: Classified as a non-HAP (Hazardous Air Pollutant) in many regions, with a lower toxicity and higher flash point than many traditional solvents.
Surface Tension Reduction: Efficiently reduces surface tension to improve wetting and adhesion on various substrates.
