RHEOBYK-415 is a liquid rheology additive for solvent-borne baking coatings and forced drying systems to improve anti-sagging properties. It works together with the binder and builds a three-dimensional network via hydrogen bonds and van der Waals forces. In addition to the dosage level and the polarity of the system, the degree of disentanglement of the higher molecular weight additive is key to the effectiveness. The higher molecular weight and the more pronounced pseudoplastic flow behavior are the reasons for the more temperature-stable viscosity behavior of RHEOBYK-415, even at higher drying temperatures.

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.
