A silicone composition comprising: (a) a first silane of the formula: ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9, and R.sub.10 are independently selected from hydrogen, halo, and organo radicals; and n is an integer having a value of from 1 to 4; (b) a second silane of the formula: ##STR2## wherein: R.sub.11 and R.sub.16 are non-polymerizable groups and are independently selected from halo and organo radicals; R.sub.12, R.sub.13, R.sub.14, and R.sub.15 are independently selected from hydrogen, halo, and organo radicals; and n is an integer having a value of from 1 to 4; and (c) a polysiloxane having at least two functional groups per molecule with which said first and second silanes are cappingly reactive; wherein: (1) the first and second silanes together are provided in sufficient quantity relative to the polysiloxane to react with substantially all of the cappingly reactive functional groups of the polysiloxane; and (2) the first silane constitutes from about 50% to about 98% by weight of the total weight of the first and second silanes.
A silicone composition, comprising:
A silicone composition, comprising:
A method of capping a silicone having active hydrogen-containing functionality with (i) acrylic functionality to render the silicone photocurable in character, and with (ii) non-reactive functionality, comprising non-hydrolyzingly reacting the active hydrogen-containing functionality of said silicone with:
