  • Publication number: 20190241690
    Abstract: Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate polymers, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinkable and crosslinked compositions are free or substantially free of tackifiers. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

  • Publication number: 20180133742
    Abstract: Methods and apparatuses for applying liquid coatings are provided. A first roll (14), a second roll (16), and a nip (146) formed between the first and second rolls are provided. A coating liquid (22) is supplied to the nip. The coating liquid is smoothed, via the nip, into a substantially uniform layer (22a) of liquid coating which is transferred to a substrate (12). The second roll (16) includes a thin metal shell (40) and a resilient layer (30), the thin metal shell encases the resilient layer therebeneath, and the thin metal shell is capable of deflecting in unison with the resilient layer such that the thin metal shell is elastically deformable at the nip when in contact with the first roll (14).

  • Patent number: 8596799
    Abstract: Retroreflective sheeting includes a body layer having a structured surface with recessed faces forming cube corner cavities. A reflective film is disposed at least on the recessed faces, and a fill material fills the cube corner cavities. The fill material comprises radiation-curable materials, adhesives, or both, and preferably transparent radiation-curable pressure-sensitive adhesives. The fill material preferably forms a continuous layer covering both the recessed faces and upper portions of the structured surface.

  • Patent number: 7250611
    Abstract: A radiation curing apparatus comprises a plurality of solid state radiation sources to generate radiation that cures a first material. The solid state radiation sources can be disposed in an array pattern. Optical concentrators, arranged in a corresponding array pattern, receive radiation from corresponding solid state radiation sources. The concentrated radiation is received by a plurality of optical waveguides, also arranged in a corresponding array pattern. Each optical waveguide includes a first end to receive the radiation and a second end to output the radiation. The curing apparatus can be utilized for continuous substrate, sheet, piece part, spot curing, and/or 3D radiation-cure processes.
