Характеристики

Ключевые свойства и преимущества

Superior Solvency: Exhibits high solvency power for various resins, oils, and greases, facilitating the formulation of concentrated cleaners and high-solids coatings.
Excellent Coupling Ability: Acts as an effective intermediate, enabling the blending of water-insoluble organic components into aqueous systems.
Surface Tension Reduction: Significantly lowers the surface tension of water-based formulations, enhancing substrate wetting and adhesion.
Safety Profile: Offers lower toxicity and fewer regulatory restrictions compared to ethylene glycol propyl ethers (EP).
Controlled Evaporation: Provides a moderate evaporation rate that prevents «flash dry» issues while ensuring timely curing and drying of films.
Full Compatibility: Miscible with most organic solvents and partially soluble in water.
