specific Embodiment approach

[0023] Hereinafter, the present invention will be described in more detail with reference to preferred embodiments of the present invention.

[0024] Those skilled in the art should understand that each embodiment is only intended to describe the present invention in more detail, and the scope of the present invention is not limited by these embodiments.

[0025] The polyester film used in the present invention is not limited to a specific type, and a known conventional polyester film can be used as a base film for antistatic coating. In the present invention, the exemplary polyester film is a polyester resin polyester film, such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, and the like. It should be noted that the substrate of the antistatic coating composition of the present invention is not limited to a polyester sheet or film.

[0026] The polyester constituting the film of the present invention is obtained by polycondensing an aromatic ...

Embodiment approach 1

[0053] First, a silicone release type containing 0.05 parts by weight of conductive polymer resin based on 100 parts by weight of organopolysiloxane, 0.05 parts by weight of silane coupling agent, 5 parts by weight of organohydrogen polysiloxane, and 50 ppm of platinum chelate catalyst The composition is prepared by diluting the composition in water, and the composition has a total solid content of 2% by weight. The composition was then coated on the corona discharge-treated surface of a polyester film with a thickness of 10 microns. After coating the film with the composition, the film was dried with a hot air dryer at 180° C. for 10 seconds to produce an antistatic silicone release film having a layer coated with an antistatic silicone release composition.

Embodiment approach 2

[0055] The antistatic silicone release film was prepared in the same manner as in the above-mentioned Embodiment 1, except that 0.1 parts by weight of the conductive polymer resin was added to the composition.

Abstract

The invention relates to an antistatic silicone release film having a layer coated with an antistatic silicone release composition, and, used for semiconductors, electronics and display devices while addressing problems of static electricity generated when a general release film is separated from adhesive or an adhesive layer, and of contamination by such static electricity that causes critical product defects. The invention also relates to an antistatic silicon release film that can reduce product contamination caused by static electricity in peeling the film from adhesive or an adhesive layer, and achieves close adhesion between a substrate and a coated layer because of no interruption in curing a release layer, and also thereby has a stable release property.

Description

Technical field [0001] The present invention relates to an antistatic silicone release film, which has a layer coated with an antistatic silicone release composition, and more specifically, to an antistatic silicone release film, which has an antistatic silicone release film The layer coated with the release composition is used in semiconductors, electronics and display devices, and at the same time solves the problem of static electricity generated when the ordinary release film is separated from the adhesive and the adhesive layer and the direct result of this Pollution caused by static electricity caused by serious product defects. The present invention also relates to an antistatic silicone release film, which can reduce product contamination caused by static electricity when the film is peeled from the adhesive or adhesive layer. Since there is no hindrance in curing the release layer, the substrate and the The coated layers have good adhesion and thus stable release performa...
