  • Patent number: 12076746
    Abstract: A textured press plate for use in the manufacture of decorative laminate is provided. The textured press plate is manufactured by the method include the steps of applying a UV curable acrylate mixture to a surface of a press plate substrate, irradiating the UV curable acrylate mixture with LED precure by excimer UV to create a UV-irradiated layer having a surface exhibiting micro-folding, and fully curing the UV-irradiated layer to form a textured coating layer.

  • Patent number: 11745475
    Abstract: A textured release sheet includes a substrate including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

  • Patent number: 11077639
    Abstract: A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

  • Patent number: 10933608
    Abstract: A surfacing material includes a substrate having a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an electron beam radiation curable material applied to the bottom side of the substrate. The coating is an epoxy acrylic or urethane acrylic laid upon the substrate. The epoxy acrylic or urethane acrylic is irradiated with UV-radiation to produce a UV-radiation layer wherein the epoxy acrylic or urethane acrylic is neither hardened nor is an entire layer of the epoxy acrylic or urethane acrylic crosslinked but rather the epoxy acrylic or urethane acrylic only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.
