Compositions with enhanced flexibility

A composition comprising:

• (a) flexibilizer (i) having the general formula (I):
• wherein:
• each occurrence of R1 is independently an alkyl group having from 1 to 6 carbon atoms, a phenyl group or an arenyl group having 7 to 12 carbon atoms;
• each occurrence of R2 is independently an alkyl group having from 1 to 6 carbon atoms;
• each occurrence of R3 is independently a phenyl group or an arenyl group having 7 to 12 carbon atoms;
• each occurrence of X1 is independently a hydroxyl group, an alkoxy group having from 1 to 6 carbon atoms, or an alkoxy group having from 1 to 6 carbon atoms and at least one ether or ester functional group;
• each occurrence of X2 is independently a hydroxyl group, an alkoxy group having from 1 to 6 carbon atoms, an alkoxy group having from 1 to 6 carbon atoms and at least one ether or ester functional group, or a group with the formula (II)
• wherein:
• R1, R2 and R3 are the same as defined above;
• each occurrence of subscripts a, b, c, d, e and f is independently an integer wherein a is 1 to 3;
• b is 0 to 500, c is 1 to 500, d is 0 to 10, e is 0 to 50, and f is 0 to 50 with the provisos that
• (1) the molar ratio of b to c is from 0:1 to 15:1, and
• (2) the molar ratio of d to c is from 0:1 to 1:1;
• (b) at least one resin selected from the group consisting of an amine-functional resin (iv), a mercapto-functional resin (v), a resin containing silanol-reacting groups and a resin containing alkoxysilyl-reacting group,
• with the proviso that when the resin (b) is the amino-functional resin (iv) or mercapto-functional resin (v), the composition further comprises,
• (c) at least one curing agent (vi) selected from the group consisting of isocyanate-containing compound (vii), blocked isocyanate-containing compound (viii) and aminoplast (ix).
