Abstract
A composition contains an organopolysiloxane having the average chemical structure (I):[R'RSiO—(RSiO)]—Si—[OSiR]—Y—Si(OR)  (I)where: R is independently in each occurrence selected from alkyl, aryl, substituted alkyl and substituted alkyl groups having from one to 8 carbon atoms; R′ is independently in each occurrence selected from R and terminally unsaturated alkylene groups having from 2 to 6 carbon atoms; Y is selected from a group consisting of: X, and X—(RSiO)SiR—X; where p has an average value in a range of one to 3; and X is independently in each occurrence selected from alkylene and substituted alkylene groups having from one to 6 carbon atoms; and the average values for subscripts m and n are each greater than zero and independently selected so that the average value for the sum of all of the average m values and the average n value is in a range of 30-200.
