35. A method of making a curable silicone release coating
composition comprising:
(I) mixing;
(A’) an organopolysiloxane compound having its formula
selected from the group consisting of:
(i) R23SiO(R2SiO)x(RR2SiO)ySiR23,
(ii) R23SiO(R2SiO)xSiR23, and
(iii) R23SiO(RR2SiO)ySiR23,
wherein R is independently selected from monovalent hydrocarbon
or halohydrocarbon radicals free of aliphatic unsaturation and
having from 1 to 20 carbon atoms, R2 is independently selected
from the group consisting of methyl and an alkenyl group selected
from the group consisting of 5-hexenyl, 6-heptenyl, 7-octenyl, 8-
nonenyl, 9-decenyl, 10-undecenyl, 4,7-octadienyl, 5,8-nonadienyl,
5,9-decadienyl, 6,11-dodecadienyl, and 4,8-nonadienyl, x has a
value of from greater than zero to 7000, and y has a value of
from greater than zero to 350 with the proviso that there is at
least two alkenyl groups as defined above per compound;
(B’) an organohydrogensilicon compound;
(C’) a platinum group metal-containing catalyst;
(D’) a silylated acetylenic compound having its formula
selected from the group consisting of:
R3 R3
