摘要:
A process for applying a protective self-adhesive film onto a coat-finished product having an object unnecessary to be protected by the protective self-adhesive film, which process comprises (1) the following steps: applying a perforated self-adhesive film (a) having a perforation onto the surface of the coating of the coat-finished product so that an area occupied by the object may be positioned within the perforation, applying a protective self-adhesive film onto the object, the perforated self-adhesive film (a) and such a part of the coating of the coat-finished product as not to be covered with the perforated self-adhesive film (a), and removing an unnecessary portion of the protective self-adhesive film over the perforation; or (2) the following steps: applying the protective self-adhesive film onto the object and a coating of the coat-finished product, cutting out such an unnecessary portion of the protective self-adhesive film as positioned over the area occupied by the object by use of a cylindrical cutting device comprising a ring-shaped cutter blade and a cylindrical pressing means, preferably further comprising a ribbon heater to heat the cutter blade to press and adhere the remaining portion of the protective self-adhesive film around the onto the coating of the coat-finished product, and removing the cut unnecessary portion of the protective self-adhesive film by suction.

摘要:
A pressure-sensitive adhesive comprising 100 parts by weight of an isobutylene polymer and 0.001 to 5 parts by weight of at least one release control agent selected from the group consisting of an alcohol having a molecular weight of 90 to 300 and an oxygen atom content of 8.5% or more or a derivative thereof and a carboxylic acid having a molecular weight of 70 to 400 and an oxygen atom content of 11% or more or a derivative thereof; and a surface protecting material having a pressure-sensitive adhesive layer comprising the adhesive. The adhesive has well-balanced characteristics in initial adhesion, retention of initial adhesion, and weather resistance.
摘要:
A sheet for protecting a paint film which does not deteriorate or discolor the paint film even when the sheet is adhered to protect the paint film under the condition containing acidic rainwater or detergent and can maintain the adhered state over an extended-period of time without peeling off is disclosed. The sheet for protecting a paint film comprises a porous substrate and a pressure-sensitive adhesive layer formed on one surface of the porous substrate. The sheet has an air permeability in a direction of sheet thickness of 20,000 sec/100 cc or more and a moisture permeability in a direction of sheet thickness of 2,000 g/m2·24 hr or more. The sheet for protecting a paint film further comprises a porous substrate and a pressure-sensitive adhesive layer formed on one surface of the porous substrate, wherein the porous substrate has an ultraviolet transmission of 10% or less at a wavelength of from 190 to 370 nm.

摘要:
A sheet for protecting a paint film is disclosed, which does not cause deterioration or discoloration the paint film even when the sheet is adhered to protect the paint film under the condition containing water or water vapor over a long period of time and thus can maintain the adhered state without peeled off the sheet. The sheet for protecting a paint film comprises a multi-layer substrate comprising a water or water vapor barrier layer as a surface layer and a water or water vapor-permeable layer as a back, and a pressure-sensitive adhesive layer formed on the water or water vapor-permeable layer.
摘要:
A sheet for protecting paint film comprising a support having formed thereon a rubber adhesive layer comprising an isobutylene polymer having a degree of dispersion of from 1 to 2.3 and a weight average molecular weight of 300,000 to 600,000 (the domain A in the FIGURE) as the base polymer.The paint film protecting sheet has the compatibility of the prevention of the occurrence of a microdeformation and a good peelability. That is, when an article such as automobiles having a paint film applied with the protecting sheet is placed outdoors for a long period of time at high temperature, the paint film is hard to deform and the sheet can be easily peeled even after adhering for a long period of time.
