CLAYTONE® 40 is an organophilic bentonite derivative which is used as thixotropic thickener and anti-settling agent in solvent based coating systems of low to medium polarity. It is a traditional organoclay requiring the addition of an activator to achieve full efficiency. As organophilic smectite product, it can swell in organic media and build a gel structure (card-house structure). Weak hydrogen bonding between the single smectite platelets is the reason for this thixotropic gel structure. For optimum efficiency the complete separation of the platelets (complete dispersion of agglomerates into primary particles) is necessary.

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.
