Dual curing polymers and methods for their preparation and use

A method comprising:

• combining ingredients comprising:
• (A) a polyorganohydrogen siloxane having an average, per molecule, of one silicon-bonded hydrogen atom and one to three terminal hydrolyzable groups, where the silicon-bonded hydrogen atom and the hydrolyzable groups are bonded to different silicon atoms in the polyorganohydrogensiloxane;
• (B) a polyorganohydrogen siloxane having an average, per molecule, of one silicon-bonded hydrogen atom and one to three terminal epoxy functional organic groups, where the silicon bonded hydrogen atom and the epoxy functional organic groups are bonded to different silicon atoms in the polyorganohydrogensiloxane;
• and
• (C) an organofunctional polymer having an average, per molecule, of at least 3 terminal aliphatically unsaturated organic groups;
• and
• (D) a hydrosilylation catalyst;
• thereby making a polymer
• where the polymer comprises units of formulae:
• where
• subscript a has a value of 1 or more,
• subscript e has a value of 1 or more,
• a quantity (a+e) has a value of 3 or more,
• each subscript s independently has a value of 1, 2, or 3;
• each subscript t independently has a value of 1, 2, or 3;
• each R1 is independently an oxygen atom or a divalent hydrocarbon group;
• each R2 is independently monovalent hydrocarbon group free of terminal aliphatic unsaturation;
• each X is independently a monovalent hydrolyzable group;
• and
• each J is independently a monovalent epoxy functional organic group.
