DISPERBYK®-2152 is an emission-free, hyperbranched wetting and dispersing additive for solvent-free epoxy systems and other reactive systems. Achieving excellent deflocculation and stabilization requires an additive with highly efficient pigment-affinic groups. In general, those pigment-affinic groups are aminic in nature and can react with the epoxy resins.
Due to the special hyperbranched structure of DISPERBYK®-2152 the aminic pigment-affinic groups are encapsulated by polyester side chains; this prevents reaction with the epoxy resin, and, as a result, long-term storage stability is achieved. The additive contains no solvents or volatile components and fulfills the strict requirements of the German AgBB as well as French VOC standards

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.
