Novel polyurea siloxane coating compositions are contemplated, the compositions being the reaction products of isocyanate prepolymers and resin blends, with the resin blends containing siloxane copolymers in addition to conventional polyurea monomer and polymer resin reactants. Specifically, it has been found that reaction products having superior gloss retention, water resistance, temperature resistance, and chemical resistance may be formed from isocyanate prepolymers and resin blends having various amounts of poly[(3-aminopropyl)methylsiloxane-co-diphenylsiloxane] in addition to aromatic and/or aliphatic polyamines.
考虑使用新型聚脲硅氧烷涂料组合物,这些组合物是异氰酸酯预聚物和树脂混合物的反应产物,其中树脂混合物除了传统的聚脲单体和聚合物树脂反应物外,还含有硅氧烷共聚物。具体来说,研究发现,异氰酸酯预聚物和树脂混合物中除了芳香族和/或脂肪族多胺外,还含有不同量的聚[(3-氨基丙基)甲基硅氧烷-共二苯基硅氧烷],可以形成具有优异光泽保持性、耐水性、耐温性和耐化学性的反应产物。
