主要特点与优势

Superior Solvency: Exhibits strong dissolving power for a variety of resins such as cellulose, acrylics, and polyurethanes, ensuring uniform formulations.
Slow Evaporation Profile: The low volatility promotes exceptional flow, leveling, and gloss in coatings, preventing surface defects like “orange peel.”
Enhanced Safety Profile: Features a high flash point (approx. 88°C) and low vapor pressure, minimizing inhalation risks and flammability hazards during processing.
Environmental Compatibility: Readily biodegradable and offers a lower toxicological profile compared to halogenated or aromatic solvents.
Miscibility: Partially soluble in water and highly miscible with most organic solvents, allowing for versatile formulation flexibility.
