Характеристики

Ключевые свойства и преимущества

  • 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.
Спецификации

Технические особенности

  • Molecular Formula: C6H10O4 (Molecular Weight: 146.14 g/mol).
  • Boiling Point: Typically ranges from 190circC to 192circC at 760 mmHg, classifying it as a high-boiling solvent.
  • Density: Approximately 1.106 g/cm3 at 20circC, making it denser than water.
  • Low Moisture Content: Generally produced with high purity (min. 99%) and very low water content to prevent side reactions in sensitive systems.
  • Refractive Index: Approximately 1.415 at 20circC, contributing to clear, high-gloss finishes in optical and coating applications.
  • Vapor Pressure: Very low at 0.25 mmHg at 20circC, facilitating long open times in industrial processes.
