Harcryl® 1228 M

1 of 3 products in this brand
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.

Key Attributes

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 M to easily incorporate into many coating systems.

Usage Recommendation

Harcryl® 1228 M 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.
