    摘要: A drywall tape including a fiber matrix having a first side and an opposing second side; a sandable coating on at least a portion of the first side of the fiber matrix, wherein the sandable coating is a first color; and, an adhesive element on at least a portion of the second side of the fiber matrix. Additionally, a system for preventing oversanding of surfaces including a matrix having a first side and an opposing second side; and, at least one sandable coating on at least a portion of the first side of the flexible matrix, wherein the sandable coating is a different color than the color of joint compound when dried.

    摘要: There is provided a pressure sensitive adhesive sheet for wafer protection (1a) comprising a base material (11), an intermediate layer (12), and a pressure sensitive adhesive layer (13) in this order, wherein the intermediate layer is a layer formed from an intermediate layer-forming composition containing 100 parts by mass of a non-energy ray-curable acrylic polymer (A) and 25 parts by mass or more of an energy ray-curable acrylic polymer (B) having a mass average molecular weight of 50,000 to 250,000; and the pressure sensitive adhesive layer is a layer formed from a pressure sensitive adhesive composition containing an energy ray-curable acrylic polymer (C). The inventive pressure sensitive adhesive sheet for wafer protection is excellent in interfacial adhesion between an intermediate layer and a pressure sensitive adhesive layer after energy ray irradiation. Therefore, the pressure sensitive adhesive sheet for wafer protection can suppress the deposition of a residue of the pressure sensitive adhesive layer to an adherend when it is removed after laminated to the adherend, has excellent followability even to an adherend having a large unevenness difference on a wafer surface, and has a small rate of change of adhesive strength even after being stored for a long period of time and has excellent stability with time.

    摘要: A tape closure system is shown and described herein. The tape closure system includes a first tape component having a pressure sensitive adhesive and a second tape component having a pressure sensitive adhesive, where at least one of the pressure sensitive adhesives has a modified surface to reduce the tack of the surface such that when the first and second pressure adhesives are brought into contact with one another they may sufficiently adhere to one another to form a seal but are still separable from one another and able to be repeatedly opened and sealed.
