Key Features
✧ Exceptional ecological profile and regulatory compliance – Formulated as an APEO-free, water-based acrylic emulsion with minimal volatile organic compound (VOC) content, it complies with the most stringent international ecological regulations and sustainability goals, including REACH, EPA, and various eco-label standards for architectural coatings.
✧ Superior water and chemical resistance – The cured film exhibits outstanding resistance to water, chemicals, and blocking, ensuring long-lasting protection for interior and exterior architectural surfaces. Resistance properties can be finely tuned through neutralization with amines or ammonia of varying boiling points.
✧ Excellent formulation flexibility and compatibility – Demonstrates broad compatibility with other aqueous systems, including water-based polyurethane dispersions (PUDs). It can be blended to create economical matte coatings or used as a high-performance grinding resin for color pastes, ensuring uniform dispersion and stability.
✧ Versatile curing and application profiles – Water based acrylic resin can be air-dried or baked. When neutralized with sodium hydroxide (NaOH), it creates a water-washable temporary coating. After high-temperature curing, it decomposes cleanly without carbon residue, making it suitable for colored glass ceramic coatings.
✧ Optimized functional performance – Delivers excellent barrier properties and can be combined with carbodiimide crosslinkers for enhanced resistance. When blended with specific acrylic emulsions (e.g., 6037), it significantly improves low-temperature heat-seal strength for packaging-related applications.

An aqueous colloid that requires alkali neutralization. The water resistance and resolubility can be adjusted with ammonia and amines with different boiling points. Also can be neutralized with NaOH to make water-washable coating. After high-temperature baking and decomposition, there is no residual carbonized black matter, so it can be used as colored connecting material for glass ceramics. Also can be used as resin for grinding color paste. |
