Harcryl® 1228 M
- CAS Number
- 52628-03-2
- Chemical Name
- 2-Hydroxyethyl methacrylate phosphate
Harcryl® 1228 M is a free acid phosphate ester of 2-HEMA (hydroxyethyl methacrylate). It is predominantly composed of the monoalkyl phosphate ester, making it easy to incorporate into a variety of polymer systems. The ratio of mono-alkyl to dialkyl phosphate makes Harcryl® 1228 M more hydrophilic than Harcryl® 1228. In addition, it is inhibited by the addition of 400 ppm hydroquinone.
