Defoamer polymer molecule.FoamStar, a new defoamer polymer molecule for high-performance, sustainable coatings, has been developed by Cognis. The FoamStar technology combines defoaming and wetting performance with environmental compatibility. It is based on a hyper-branched polymer molecule with a three-dimensional star-shaped structure, which contains both hydrophilic hydrophilic /hy·dro·phil·ic/ (-fil´ik) readily absorbing moisture; hygroscopic; having strongly polar groups that readily interact with water. hy·dro·phil·ic adj. and hydrophobic hydrophobic /hy·dro·pho·bic/ (-fo´bik) 1. pertaining to hydrophobia (rabies). 2. not readily absorbing water, or being adversely affected by water. 3. elements. It functions as a "second surfactant Surfactant Definition Surfactant is a complex naturally occurring substance made of six lipids (fats) and four proteins that is produced in the lungs. It can also be manufactured synthetically. ," interacting with the primary surfactant to destabilize de·sta·bi·lize tr.v. de·sta·bi·lized, de·sta·bi·liz·ing, de·sta·bi·liz·es 1. To upset the stability or smooth functioning of: the foam bubbles. For additional information: +49-2173-4995-142, ina.puscasu@cognis.comm, or www.cognis.com. |
