- a fluoropolyether group-containing compound has water and oil repellency, chemical resistance, lubricity, releasability, antifouling property and the like because its surface free energy is very small. Utilizing its properties, it is widely used industrially for water and oil repellent and antifouling agents such as paper and fiber, lubricants for magnetic recording media, oil repellents for precision equipment, mold release agents, cosmetics, and protective films. ing. However, the property means that it is non-adhesive and non-adhesive to other substrates at the same time, and even if it can be applied to the surface of the substrate, it was difficult to make the film adhere to it. .
- a silane coupling agent is well known as a material for bonding a substrate surface such as glass or cloth and an organic compound, and is widely used as a coating agent for various substrate surfaces.
- the silane coupling agent has an organic functional group and a reactive silyl group (generally a hydrolyzable silyl group such as an alkoxysilyl group) in one molecule.
- the hydrolyzable silyl group causes a self-condensation reaction with moisture in the air to form a film.
- the coating becomes a strong coating having durability by chemically and physically bonding the hydrolyzable silyl group to the surface of glass or metal.
- Lenses and antireflection films surface-treated with a composition containing a fluoropolyether group-containing polymer-modified silane in which a hydrolyzable silyl group is introduced into the fluoropolyether group-containing compound are excellent in wear resistance and releasability. The slipperiness is not enough.
- Rf is a monovalent fluorooxyalkyl group or divalent fluorooxyalkylene group-containing polymer residue
