A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.

The present disclosure further relates to a method for preparing an adhesive printing form attachment layer, as well as a printing cylinder comprising it, the use of the an adhesive printing form attachment layer for fixing a flexographic printing plate during a printing operation on a printing cylinder, and a method of operating a printing machine wherein the adhesive printing form attachment layer is used.

The invention relates to a below grade, blind side, waterproofing sheet membrane with adhesive and high reflectivity granular particle layer, and having a top release liner, and a bottom release liner, enhancing bond strength between sheets, and be able to fully bond to concrete/shotcrete, and a method of making, and using same. The inventive waterproofing sheet membrane with adhesive, has at least one layer of high reflectivity granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is between about 35 percent to 80 percent reflectivity on a standard reflectivity scale. The waterproofing sheet membrane has an adhesive layer having embedded therein high reflectivity granular particles is used in any building or wall construction, and can be placed under or around a foundation of a building or on its below grade blind side retaining walls, etc.

A pressure relief cushion includes an elastic layer which is made from a viscoelastic foam material, an adhesive carrying layer disposed on the elastic layer and including an adhesive portion and a carrier portion for carrying the adhesive portion, a hydrogel layer disposed on the adhesive carrying layer opposite to the elastic layer, and a detachable film disposed on the hydrogel layer opposite to the adhesive carrying layer.

A protective film 10 of the present invention includes a base material layer and a pressure sensitive adhesive layer, and is used by being attached to a resin substrate 21 at the time of performing heat bending on the resin substrate 21. The pressure sensitive adhesive layer contains a polyolefin having a melting point of lower than 125 C. The base material layer has a first layer which contains a polyolefin having a melting point of 150 C. or higher, and a second layer which contains an adhesive resin. In a case of heating the protective film 100 having such a configuration, in a state of being interposed between two attaching substrates which are formed of polycarbonate, at 145 C. for 30 minutes, peeling off one attaching substrate on the side of the pressure sensitive adhesive layer at 25 C., and then viewing a surface of the one attaching substrate in a plan view, a residual ratio of an area where the pressure sensitive adhesive layer remains is 5% or less.
