摘要： This invention relates to the process of preparation and application of a plural component, fast cure phenolic/polyurea elastomer coating co-polymer system. The disclosed coating system is prepared from the reaction of an isocyanate component and an amine terminated resin blend component. Each of the two components may individually or both contain a phenolic resin based product as part of the active hydrogen donation for the reaction with the isocyanate. These phenolic/polyurea co-polymers are characterized as having significantly improved chemical resistance and lower moisture vapor transmission through the coating system over conventional polyurea elastomer coating systems, thus making the coatings suitable for highly corrosive environments.
摘要翻译：本发明涉及多组分快速固化酚醛/聚脲弹性体涂料共聚物体系的制备和应用的方法。所公开的涂料体系由异氰酸酯组分和胺封端的树脂共混组分的反应制备。两种组分中的每一种可以单独或两者含有酚醛树脂基产物，作为与异氰酸酯反应的活性氢供体的一部分。这些酚/聚脲共聚物的特征在于通过涂覆体系比常规聚脲弹性体涂料体系具有显着改善的耐化学性和较低的水蒸气透过性，从而使涂层适合于高腐蚀性环境。

摘要： Spray polyurea elastomers are disclosed made from an (A) component and a (B) component, where the (A) component has a quasi-prepolymer made from an isocyanate and an active hydrogen-containing material, such as a polyoxyalkylenepolyamine. The (B) component includes an amine resin, such as an amine-terminated polyoxyalkylene polyol which may be the same or different from the polyoxyalkylene polyamine of the quasi-prepolymer. The viscosity of the (A) component is reduced by the inclusion of an organic, alkylene carbonate, such as ethylene carbonate, propylene carbonate, butylene carbonate, dimethyl carbonate, and the like. The alkylene carbonate also serves as a compatibilizer between between the two components, thus giving an improved mix of the system.
