属性

主要特点与优势

  • Dual functionality allows for both addition polymerization and condensation cross-linking, providing significant formulation flexibility for resin chemists and industrial material manufacturers.
  • Superior wetting properties and low viscosity facilitate easy incorporation into aqueous or solvent-based systems, enhancing the flow and leveling of finished coatings.
  • The pendant hydroxyl group significantly improves the adhesion of polymers to metallic and polar substrates, ensuring long-term durability in harsh environments.
  • Exhibits excellent weatherability and UV resistance, making it an ideal choice for outdoor coatings that must maintain color and structural integrity.
  • High chemical reactivity ensures rapid curing cycles in industrial processes, improving throughput for manufacturing operations involving thermoset plastics or radiation-cured inks.
规格

技术亮点

  • Molecular Formula: C6H10O3 with a molecular weight of approximately 130.14 g/mol, representing a pure monomer grade for high-performance chemical synthesis and polymerization.
  • Boiling point is approximately 77 degrees Celsius at 5 mmHg, indicating low volatility at standard conditions which minimizes VOC emissions during application.
  • Flash point is recorded at 99 degrees Celsius using the closed cup method, requiring specific storage protocols to ensure fire safety and stability.
  • Solubility profile includes high miscibility with water and common organic solvents such as alcohols, ethers, and aliphatic hydrocarbons, allowing for diverse formulation strategies.
  • Standard purity levels typically exceed 97 percent, with moisture content strictly controlled below 0.2 percent to prevent premature reaction or degradation of the monomer.
实际行业应用

应用领域

  • Used extensively in the manufacture of automotive topcoats and industrial finishes where high gloss, scratch resistance, and chemical durability are primary performance requirements.
  • Serves as a critical reactive diluent in UV-curable inks and coatings, providing the necessary viscosity reduction while participating in the polymerization process.
  • Applied in the production of pressure-sensitive adhesives to improve shear strength and cohesive properties while maintaining the necessary tack for bonding various surfaces.
  • Utilized in textile finishing agents and leather treatment chemicals to impart softness, water resistance, and improved dye fastness to natural and synthetic fibers.
  • Employed in the synthesis of specialty thermosetting resins for glass fiber reinforcement and electronic encapsulation where thermal stability and moisture resistance are vital.
