Harcryl® 1228
- CAS Number
- 52628-03-2
- Chemical Name
- 2-Hydroxyethyl methacrylate phosphate
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.

- 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.; 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 to easily incorporate into many coating systems.

- Usage Recommendations
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.
