Fluorine based polymer
WebTraditionally, a fluoropolymer or fluoroplastic is defined as a polymer consisting of carbon (C) and fluorine (F). Sometimes they are referred to as perfluoropolymers to distinguish them from partially fluorinated polymers, fluoroelastomers, and other polymers that contain fluorine in their chemical structure. WebDescription. 1H,1H,2H,2H-Perfluorooctyltriethoxysilane is used as an active component of fluorine modified ORMOCER (organically modified ceramics) coating materials. It is a fluorine based polymer having low surface free energy, enhances its anti-adhesive behavior of polar and non-polar substances. Its wetting property acts in repelling aqueous ...
