    • A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface. The coating utilizes hydrophobic nanoparticles of fumed silica and/or titania in a solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and/or abrasion found in previous coatings of similar nature. Virtually transparent coating are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes. Embodiments of the hydrophobic self-cleaning coating composition can be produced resulting in a clear coating or in some cases a translucent dirt repellant film or coating on painted material, plastic, metal, glass, ceramic, fiberglass or a polymer substrate. One preferred coating composition utilizing an effective amount of a treated fumed silica in a solvent forms a coated surface providing a contact angle of at least 165 degrees as compared to water having a contact angle of from 10 to 15 degrees on a noncoated surface. The self-cleaning coating composition imparts a degree of hydrophobicity to a surface so that the treated surface will have a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher.
    • 疏水性自清洁涂料组合物,其可以通过常规方法施用,例如通过将组合物喷涂到表面上形成湿表面和干污垢涂层的表面上。 该涂层使用在环境温度下蒸发的溶剂中的热解法二氧化硅和/或二氧化钛的疏水性纳米颗粒。 该涂层解决了在类似性质的先前涂层中发现的耐紫外线性差,不透明外观和/或耐磨性差的问题。 与通常为白色或不透明的相当的疏水性的常规涂层相比,产生几乎透明的涂层。 可以通过单一且容易的喷涂方法施加涂层,并且可以通过在环境温度下蒸发溶剂5至10分钟来干燥膜来实现超疏水性。 可以制造疏水性自清洁涂料组合物的实施方案,从而形成透明涂层,或在某些情况下产生在涂漆材料,塑料,金属,玻璃,陶瓷,玻璃纤维或聚合物基材上的半透明防污膜或涂层。 使用有效量的经处理的热解法二氧化硅在溶剂中的一种优选的涂料组合物与在非涂层表面上的接触角为10至15度的水相比形成了涂覆表面,其提供至少165度的接触角。 自清洁涂料组合物赋予表面一定程度的疏水性,使得与具有90度或更高的滑动倾斜角的未涂覆表面上的水相比,经处理的表面将具有小于2度的倾斜倾斜角度 。

    • An aqueous wheel and/or tire cleaning solution for removing the dirt from the surface of aluminum, chrome, stainless steel, painted steel, painted aluminum, clear coated aluminum, rubber, and plastic wheels and tires without scrubbing by applying the cleaning solution to the wheel and/or tire then rinsing the wheel and/or tire with water. Selected polymers include a polyvinylpyrrolidone, a poly(N-vinylimidazole), a poly(4-vinylpyridine-betaine), and/or a poly(4-vinylpyridine-N-oxide) each one of which can be used with conventional wheel cleaning components such as an acid or alkaline-based cleaning formulation to dramatically improve its cleaning power. These polymers can attach to organic and inorganic dirt particles forming a complex with them for easy removal from the wheel and/or tire during rinsing, leaving the wheel and/or tire clean without scrubbing the wheel or tire surface.
    • 一种用于从铝,铬,不锈钢,涂漆钢,涂漆铝,透明涂层铝,橡胶和塑料轮子和轮胎的表面除去污垢的水性轮和/或轮胎清洁溶液,而不用通过将清洁溶液施用于 轮和/或轮胎然后用水冲洗车轮和/或轮胎。 所选择的聚合物包括聚乙烯吡咯烷酮,聚(N-乙烯基咪唑),聚(4-乙烯基吡啶 - 甜菜碱)和/或聚(4-乙烯基吡啶-N-氧化物),其中每一种可与传统的轮清洁组分一起使用 例如基于酸或碱的清洁制剂,以显着提高其清洁能力。 这些聚合物可以附着到与它们形成复合物的有机和无机污垢颗粒中,以便在漂洗过程中容易地从轮和/或轮胎中除去,从而使车轮和/或轮胎清洁,而不会擦拭车轮或轮胎表面。
