Harcryl® 1228 M is a free acid phosphate ester of 2-HEMA (hydroxyethylmethacrylate.) The product is inhibited with 400 ppm of added hydroquinone. Harcryl® 1228 M is predominatly composed of the mono-alkyl phosphate ester, allowing it to be easily incorporated into a variety of polymer systems. The ratio of mono-alkyl to dialkyl phosphate makes Harcryl® 1228 M more hydrophilic than Harcryl® 1228. The main application for Harcryl® 1228M is emulsion polymerization. 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. Improved corrosion resistance due to the phosphate functional group reduces the need for additional inhibitors. The acrylic backbone allows Harcryl® 1228 M to be easily incorporated into many coating systems.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
