Harcryl® 1228 UV 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, and its polarity provides for application in hydrophilic formulations as well. The main application for Harcryl® 1228 UV is UV curable coatings, and it is inhibited with 100ppm of added MeHQ.

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 UV to easily incorporate into many coating systems.
Overview
  • Harcryl® 1228 UV 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 UV provides for application in hydrophilic formulations as well.
  • Harcryl® 1228 UV is inhibited with 400 ppm of added hydroquinone.
  • The phosphate functional group promotes adhesion to a variety of surfaces, reducing the need for pretreatments. Improving adhesion saves time and reduces layers from the coating process. Increased corrosion resistance due to the phosphate functional group reduces the need for additional inhibitors. The acrylic backbone allows  Harcryl® 1228 UV to easily incorporate into many coating systems. Harcryl® 1228 UV is recommended for radiation curable application.
