摘要： The application provides a product with a protective coating and a manufacturing method thereof. Prepare a first precursor dispersion comprising a first active organic precursor, and the first active organic precursor is a fluorine-free monomer. Prepare a second precursor dispersion comprising a second active organic precursor, and the second active organic precursor is a fluorine-containing monomer. Apply the first precursor dispersion to a product body, and dry the applied first precursor dispersion to form a first dried layer. Apply the second precursor dispersion to the first dried layer to cover the first dried layer, and dry the applied second precursor dispersion to form a second dried layer, so that the first active organic precursor and the second active organic precursor are polymerized to obtain a product with a protective coating.

摘要： The double-sided pressure-sensitive adhesive sheet of the present invention includes a substrate film, a first pressure-sensitive adhesive layer, a second pressure-sensitive adhesive layer, and a release liner. The substrate film has a first surface and a second surface opposite the first surface. The first pressure-sensitive adhesive layer is disposed on the first surface, and has a first adhesive surface opposite the substrate film. The second pressure-sensitive adhesive layer is formed from a coating film of the pressure-sensitive adhesive composition applied on the second surface, and has a second adhesive surface opposite the substrate film. The release liner is in releasable contact with the first adhesive surface. The emission amount of toluene and ethyl acetate from the first pressure-sensitive adhesive layer on heating at 80° C. for 30 minutes is 10 μg/g or less.

摘要： The pressure sensitive adhesive sheet is a sheet shaped pressure sensitive adhesive including an acryl-based base polymer. The acryl-based base polymer contains an acryl-based segment and a urethane-based segment, and a content of the urethane-based segment is 3 to 30 parts by weight based on 100 parts by weight of the acryl-based segment. The urethane-based segment includes at least one urethane chain selected from the group consisting of a polyether urethane and a polyester urethane. The content of the urethane-based segment other than the polyether urethane-based segment is 15 parts by weight or less based on 100 parts by weight of the acryl-based segment.
