Hydroxypivalic acid neopentylglycolester, HPN is a building block for saturated polyesters, unsaturated polyesters and polyurethanes. HPN is suitable for polyesters for solvent-borne paints (stoving enamels for can-& coil-coating, automotive coatings, coatings for industrial applications) and for two-component paints (plastic coatings, repair coatings). HPN polyesters are used preferentially used for waterborne paints, but also suitable for polyesters in powder coatings.
HPN shows high reactivity for esterification and trans-esterification. HPN introduces optimal solubility and compatibility in polyester molecules and suppress crystallinity effectively. HPN improves the hydrolytical resistance of polyester molecules, particularly in waterborne coating

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.
