preparation example Construction
[0116] The preparation method of the silicone composition is not particularly limited, and the method of adding the component (C) just before use after uniformly mixing the components (A), (B) and optional components in advance is preferable from the viewpoint of storage time. .
[0117] A cured film is formed on the surface of a substrate by applying and curing the silicone composition of the present invention on the surface of the substrate. Thereby, the substrate release property (the property that the substrate can be perfectly peeled off from the adhesive material) is imparted. When the base material having the peeling layer of the cured product of the silicone composition of the present invention is bonded to the adhesive material, the adhesive material can be peeled off without reducing the residual adhesion rate of the adhesive material. Layers peeled off. The step of coating the silicone composition on the surface of the substrate may be performed by a conventionall...

[0182]
[0183] The above-mentioned (A), (B) and (D) components were taken into a flask according to the compounding ratio described in the following Tables 1 to 3, and 0.3 part of (E) component was further added and dissolved under stirring. (C) catalyst was added to the obtained mixture so that it might become 100 ppm in terms of platinum mass with respect to the total of (A) component and (B) component, and it stirred and mixed, and obtained the siloxane composition. Using this siloxane composition, a coated product (release film) was produced and evaluated by the method described later.

[0185] [Peel force]
[0186] Using a bar coater, the obtained composition was coated on a PET film with a thickness of 38 μm so that the solid content was 0.5 g / m 2 , Heat and cure in a hot air dryer at 120°C for 40 seconds to form a peeling layer. The peeling layer was evaluated according to the FINAT method in the following procedure.
