An adhesive article comprising a poly(meth)acrylate-based primer layer and methods of making same. The article can include a backing, a primer layer located on a first major surface of the backing, and a silicone-based adhesive located on the primer layer. The primer layer can be derived from a primer precursor comprising poly(meth)acrylate functionalities. The method can include applying a primer precursor onto a first major surface of a backing, the primer precursor comprising a compound comprising poly(meth)acrylate functionalities; irradiating the primer precursor; applying an adhesive on the irradiated primer precursor; and irradiating the adhesive and the irradiated primer precursor to form a primer layer located between the adhesive and the first major surface of the backing.

Systems and methods are described for manufacturing an adhesive tape. An example method includes: providing a plurality of adhesive webs, wherein each web includes a hot melt adhesive adhered to a backing material; providing a fabric web having a fabric material; guiding a first adhesive web from the plurality of adhesive webs into a first position proximate a first side of the fabric web; guiding a second adhesive web from the plurality of adhesive webs into a second position proximate a second side of the fabric web; applying heat and pressure to form a web of the baffle tape in which the first adhesive web is bonded to the first side of the fabric web and the second adhesive web is bonded to the second side of the fabric web; and rewinding the web of the baffle tape into a roll.

The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.

A hot melt adhesive film, and a preparation method, use, and an organosilicon polymer thereof are provided. The hot melt adhesive film includes: an inner layer, which is a polyolefin elastomer (POE); outer layers, which are an ethylene-vinyl acetate (EVA) copolymer on two surfaces of the inner layer; and intermediate layers, which are an organosilicon polymer between the inner layer and the outer layers. As intermediate layers, the organosilicon polymer plays the role of connection and transition, improves a bonding force between EVA and POE layers, and improves the stability of the hot melt adhesive film during long-term use. The hot melt adhesive film can be used as a packaging material for solar panels, touch screens, and the like.
