Abstract
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—(CH)m-SiR(OR), where A is a urethane or urea linkage group, Ris selected from Calkyl, alkenyl, alkoxy, aminoalkyl, aryl and (meth)acryloxyalkyl groups, Ris each substituted or unsubstituted Calkyl or C-Caryl 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.
