    摘要： 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.
