Характеристики

Ключевые свойства и преимущества

Aprotic Structure: The absence of active hydrogen atoms makes it compatible with reactive chemistry, such as isocyanates in polyurethane systems.
High Solvency Power: Effectively dissolves a wide range of resins, including acrylics, epoxies, polyurethanes, and alkyds.
Excellent Stability: Demonstrates superior hydrolytic stability, allowing for use in waterborne formulations without the risk of pH drift or chemical breakdown.
Safety Profile: Not classified as a HAP or a SARA 313 regulated substance; it features low acute toxicity and is generally mild on skin contact.
Coupling Efficiency: Acts as an bridge-solvent, facilitating the blending of water with oil-soluble components in stable emulsions.
Low Odor: Provides a comfortable working environment for indoor industrial applications.
