    • A two-package moisture curable composition is provided. The composition comprises a first part comprising at least one silane terminated polyurethane and a second part comprising at least one silanol terminated polysiloxane; wherein the silane terminated polyurethane based polymer has at least one end group of the general formula: -A-(CH2)m-SiR1n(OR2)3-n, where A is a urethane or urea linkage group, R1 is selected from C1-12 alkyl, alkenyl, alkoxy, aminoalkyl, aryl and (meth)acryloxyalkyl groups, R2 is each substituted or unsubstituted C1-1-8 alkyl or C6-C20 aryl groups, m is an integer from 1 to 60 and n is an integer from 0 to 1; wherein the silane terminated polyurethane is prepared using natural oil polyols and their derivatives; and wherein the composition, after moisture cured, forms a surface whose water contact angle is larger than 101°. The composition is suitable for applications in antifouling coatings which afford low surface energy and improved mechanical performance.
    • 提供了两包装湿气固化组合物。 所述组合物包括包含至少一种硅烷封端的聚氨酯的第一部分和包含至少一种硅烷醇封端的聚硅氧烷的第二部分; 其中所述硅烷封端的聚氨酯基聚合物具有至少一个具有以下通式的端基:-A-(CH 2)m -SiR1n(OR 2)3-n,其中A是氨基甲酸酯或脲键,R1选自C1- 12烷基,烯基,烷氧基,氨基烷基,芳基和(甲基)丙烯酰氧基烷基,R2各自为取代或未取代的C1-1-8烷基或C6-C20芳基,m为1至60的整数,n为 0到1; 其中所述硅烷封端的聚氨酯是使用天然油多元醇及其衍生物制备的; 并且其中所述组合物在水分固化之后形成水接触角大于101°的表面。 该组合物适用于提供低表面能和改善的机械性能的防污涂料中。
