1. An addition-curable composition comprising:
(a) an alkenyl-terminated perfluoroether; and (b) a hydrosilane-terminated extended perfluoroether, wherein the hydrosilane-terminated extended perfluoroether comprises a compound having the structure of Formula (9);
A-CH2—CH2-PFE-CH2—CH2-A′-CH2—CH2-PFE-CH2—CH2-A (9) wherein:
each A- is independently selected from a moiety of Formula (2c): wherein:
each R1 is independently selected from C1-4 alkyl, C5-6 cycloalkyl, phenyl, and —O—Si(R2)3-m(H)m, wherein each R2 is independently C1-4 alkyl; and m is selected from 0, 1, and 2; andn is an integer from 1 to 6;-A′- comprises a moiety of Formula (2b): wherein:
each R1 is independently selected from C1-4 alkyl, C5-6 cycloalkyl, phenyl, and —O—Si(R2)3-m(H)m, wherein each R2 is independently C1-4 alkyl; and m is selected from 0, 1, and 2; andn is an integer from 1 to 6; and—CH2—CH2-PFE-CH2—CH2— is derived from an alkenyl-terminated perfluoroether CH2═CH2-PFE-CH2═CH2 wherein -PFE- comprises perfluoroether groups. |
