POLYVEST® MA 75 is a maleic anhydride adduct of a low molecular weight 1,4-cis polybutadiene which has succinic anhydride groups randomly distributed along the polymer chains. This makes the originally apolar polybutadiene more polar and accessible for various chemical reactions. The polar, hydrophobic hydrocarbon resin POLYVEST® MA 75 is a highly reactive binder featuring characterized by: high chemical resistance, high water resistance, high electrical insulation properties, high cold resistance, good solubility in aliphatic, aromatics and ethers, good compatibility with long-oil alkyd resins, rosin resins and zinc resonates. POLYVEST® MA 75 is used in adhesives and sealants compositions, electrical insulations and potting compounds (2pack systems), polymeric chalk activator in EPDM-compounds, modifier in carbon black filled EPDM-compounds, modifier in silica filled rubber compounds, modifier in rubber compounds for car tires, modifier in silicone sealants, and many more.
The Evonik Coating & Adhesive Resins business is based on their backbone chemistry of polyesters, amorphous poly-alpha-olefins, FT-waxes, polybutadienes and polyacrylates. They develop individual polymer solutions according to customer needs.

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.
