BYK®-3550 is a patented technology of a surface-active additive based on a silicone acrylate copolymer. It leads to a strong reduction of the surface tension of the paint system. Therefore, it improves the substrate wetting and prevents cratering. Depending on the polarity of the system, BYK®-3550 shows different properties. In polar systems the additive shows an excellent compatibility in the coating, which leads to a homogeneous distribution in the film.
BYK has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology (CPT), launching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties. BYK invests approximately 7.5% of its earnings in R&D—three times more than the industry average.

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.
