Provichem 2203 is a very effective stabiliser for vinyl acetate and acrylic dispersions, where it is introduced during the emulsion polymerisation. It behaves like an anionic monomer and becomes an integral part of the polymer particles. The incorporated sulfonate groups stabilise the polymer dispersion by an electrostatic mechanism. Unlike surfactant-type stabilisers, Provichem 2203 will not desorb from the polymer particles. It retains its stabilizing effect even under more severe conditions, such as high shear and freezing conditions. Provichem 2203 provides superior mechanical stability during formulation (especially high solid latex), storage (for example in winter time), transport and final use of the water-based coatings and adhesives.

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.
