[0379] Preparation of surface treatment agent and formation of cured film

[0380] A hydrolyzable group-containing silane compound modified with a fluorooxyalkylene group-containing polymer of [Compound 1] to [Compound 4] as the (A) component and Fluorinated oxyalkylene-containing polymer-modified polymers composed of silazane units modified with fluorooxyalkylene-containing polymers of [Compound 5] and [Compound 6] as the component (B) Silazane compounds were mixed and dissolved in Novec 7200 (manufactured by 3M, ethyl perfluorobutyl ether) so that the concentration would be 20% by mass, to prepare a surface treatment agent.

[0381] 10nm SiO on the outermost surface 2 Treated glass (Gorilla manufactured by Corning Incorporated) was vacuum-evaporated with 4 μl of each surface treatment agent (treatment conditions were pressure: 2.0×10 -2 Pa, heating temperature: 700° C.), and cured for 12 hours in an atmosphere at 25° C. and a humidity of 50% RH to form a cured film with ...

Abstract

A surface treatment agent can form a water repellent / oil repellent layer having particularly excellent wear durability, weather resistance, and alkali resistance, and contains a fluorinated coating agent composition containing: (A) one or more selected from hydroxy group- or hydrolyzable group-containing silanes and siloxanes modified with a fluorooxyalkylene group-containing polymer, and partial(hydrolyzed) condensates thereof; and (B) a fluorooxyalkylene group-containing polymer-modified polysilazane formed of silazane units modified with a fluorooxyalkylene group-containing polymer, wherein the number-average molecular weight of fluorooxyalkylene group-containing polymer residues in the component (A) is 1,500-10,000, the number-average molecular weight of fluorooxyalkylene group-containing polymer residues in the silazane units modified with the fluorooxyalkylene group-containing polymer in the component (B) is 500-6,000, and the mixed mass ratio between the component (A) and the component (B) is 10:90 to 90:10.

Description

technical field [0001] The present invention relates to a fluorine-containing coating agent composition, in detail, to a fluorine-containing coating agent composition for forming a coating film excellent in water and oil repellency, abrasion resistance, and weather resistance, and a surface treatment agent comprising the composition and Items that have been surface treated with this surface treatment agent. Background technique [0002] Conventional surface treatment agents are often those that exhibit good water and oil repellency with respect to glass, but there are no surface treatment agents that are excellent in balance between wear resistance, weather resistance, alkali resistance, and the like. [0003] Generally, a compound containing a fluoropolyether group has water and oil repellency, chemical resistance, lubricity, mold release property, antifouling property, etc. due to its very small surface free energy. Utilizing its properties, it is widely used industrially...
