Характеристики

Ключевые свойства и преимущества

Superior Coalescing Efficiency: Effectively lowers the Minimum Film Forming Temperature (MFFT) in latex systems, ensuring smooth, durable finishes.
Excellent Solvency: Acts as a powerful solvent for a wide range of resins, including acrylic, epoxy, alkyd, and nitrocellulose.
Low Volatility: Its slow evaporation rate prevents premature drying, improving «open time» and leveling in architectural coatings.
Surface Tension Reduction: Significantly reduces the surface tension of water-based formulations, enhancing wetting and penetration on various substrates.
Enhanced Safety Profile: Features low acute toxicity and a high flash point (94^circC), reducing fire hazards during storage and handling compared to faster-evaporating solvents.
High Chemical Stability: Remains stable under a wide range of pH conditions, making it suitable for both acidic and alkaline cleaning formulations.
