Sato, Takeru; Sasaki, Muneo; Ikeda, Yoshiyuki; Kimoto, Masaki published an article in 2013, the title of the article was Preparation and estimation of super water-repellent film coated by silica and acrylic-silicon containing active methylene group.Formula: C13H20O4 And the article contains the following content:
In acrylic silicone (M-CAS) solution containing active methylene group, silica micro particles were synthesized by addition of tetraethoxysilane. When this composite film coated on a glass substrate, the water contact angle showed 120°. Furthermore, the film which the hexamethyldisilazane as silane coupling agent was added to together, showed the contact angle of 155°. However, as a result of the wear test, the contact angle of the composite film reduced to 60°. When the crosslinking agent was added in reaction solution and was cured by UV irradiation, contact angle of the coating film showed 130°. Even through wear test, the UV-irradiation-curing composite film maintained its contact angle ca.100°. Repeated coating and UV irradiation-curing formed the super water – repellent film, and even through wear test it maintained excellent water – repellency, its contact angle being reduced only to 130°C. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Formula: C13H20O4
