Dynasylan® F 8263 is a colorless liquid. It can be diluted in alcohols and various other organic solvents, e.g. n-hexane, xylol, acetone or ethyl acetate.
Dynasylan® F 8263 is a bifunctional organic compound: The silicon functional alkoxy groups can react with oxides, hydroxy and carboxy functions on the surface of a substrate. They hydrolyze with water and can establish a permanent chemical bond by elimination of ethanol/water. The fluoroalkylfunctional group provides a low energy surface.
Excellent hydrophobic and oleophobic surface properties can also be achieved by treatment with commercial fluorocarbon surfactants and resins. However, besides providing these properties Dynasylan® F 8263 can bond chemically to the surface thus creating a Si-O-substrate - bond. Subsequently, horizontal crosslinking takes place, predominantly upon evaporation of the solvent. Finally 2- and 3-dimensional networks are formed.
Dynasylan® F 8263 is a ready-for-use product and can be directly applied on a surface. Subsequently, stable coatings with a thickness of some nanometers are formed.
Through a special catalyst system which is part of the formulation, Dynasylan® F 8263 can establish coatings on several at least slightly polar polymers, like polymamide, PMMA and polycarbonate.
