Silicone pressure sensitive adhesives

A method of making an article of manufacture comprising:

• (I) applying a silicone pressure sensitive adhesive composition to at least one surface of a substrate, wherein the silicone pressure sensitive adhesive composition is obtained by a method comprising:
• (i) heating a mixture comprising:
• (A)(i) a hydroxyl-terminated polydiorganosiloxane having a viscosity of from 100 to 10,000,000 mm.sup.2 /s at 25.degree. C. or
• (ii) a mixture of (a) a hydroxyl-terminated polydiorganosiloxane and (b) a polydiorganosiloxane selected from (i) polydiorganosiloxanes terminated with monovalent hydrocarbon radicals free of aliphatic unsaturation or (ii) alkenyl-terminated polydiorganosiloxanes wherein said mixture has a viscosity of from 100 to 10,000,000 mm.sup.2/ s at 25.degree. C.;
• (B) a soluble silicone resin comprising R.sub.3 SiO.sub.1/2 siloxane units and SiO.sub.4/2 units, wherein R is selected from a monovalent hydrocarbon or halohydrocarbon radical free of aliphatic unsaturation and having from 1 to 20 carbon atoms, an alkenyl radical, or a hydroxyl radical;
• and
• (C) an organic amine compound selected from the group consisting of primary amines, secondary amines, and tertiary amines, or a metal salt of an organic amine compound selected from the group consisting of carboxylic acid salts of organic amines and quaternary ammonium salts to form a reaction product having a solids content of at least 70% and a viscosity of up to 200,000 millipascal-seconds at 25.degree.;
• and
• (ii) adding (D) an organic peroxide or azo compound to the reaction product of (i);
• and
• (II) heating the silicone pressure sensitive adhesive composition and the substrate to cure the composition.
