BYK®-3900 P is a polyacrylate, adsorbed on silicon dioxide. It is effective in powder coatings based on epoxy, polyester/epoxy, polyester, polyurethane and acrylics. This product is a very effective leveling and anti-crater additive for especially critical powder coating systems. It improves the tolerance of the powder coating system towards contamination which might occur during production or application of powder coatings ("post-wetting effect“).

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.
