Features:
- Reactive methacrylic group
- Phosphate active group
- Promotes adhesion
- Provides corrosion resistance
Benefits:- The phosphate functional group promotes adhesion to a variety of surfaces, reducing the need for pretreatments.
- Improved adhesion saves time and reduces layers from the coating process.
- Improved corrosion resistance due to the phosphate functional group reduces the need for additional inhibitors.
- The acrylic backbone allows Harcryl® 1228 to easily incorporate into many coating systems.
- Overview
- Harcryl® 1228 is a unique, functional, acrylic monomer consisting of mono and di-phosphate esters of 2-Hydroxyethylmethacrylate. The ratio of mono- alkyl to di-alkyl phosphate allows it to be easily incorporated into a variety of polymer systems. The polarity of Harcryl® 1228 provides for application in hydrophilic formulations as well.
- Harcryl® 1228 is inhibited with 400 ppm of added hydroquinone.
