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 Harcryl® 1228 to be easily incorporated into a variety of polymer systems. The polarity of Harcryl® 1228 provides for application in hydrophilic formulations as well. The primary use area for Harcryl® 1228 is emulsion polymerization and it is inhibited with 400ppm of added hydroquinone.

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.

Usage Recommendation

Harcryl® 1228 should not be used as a straight additive. As a monomer, it should be fed separately or in the monomer pre-mix. Do not mix with the initiator solution as hazardous polymerization may occur.
