Desmophen® 680 X is a hydroxyl-bearing polyester, and is ideally used as a co-reactant with Desmodur® N in the formulation of two-component polyurethane coatings with good gloss retention, lightfastness and chalking resistance. It can also be used in combination with Desmodur® L and HL in the formulation of fast-drying, two-component coatings.
Desmophen® 680 X is a hard co-reactant for Desmodur® N grades. The drying of such combinations is comparable with that of the acrylic resin/Desmodur® N systems developed specially for vehicle repair. They are therefore particularly suitable for use in the formulation of air-drying automotive and industrial coatings. Crosslinking with Desmodur® L and HL results in very fast-drying coatings which can be used in, for example, paper finishing.

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.
