  • Patent number: 11951509
    Abstract: An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.

  • Publication number: 20230250297
    Abstract: The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

  • Publication number: 20230227653
    Abstract: The present invention is directed to a flame retardant thermal interface material. The material contains a bio-based material and associated functional additives, wherein the bio-based material includes a protein and the functional additives include at least one of a char forming promotor, a char reinforce agent, a foaming agent, a thermal conductive agent, a flame suppression agent and other additives. The char forming promotor, the char reinforce agent and the flame suppression agent are used to adjust the combustion behavior of the material to render the material having desired flame retardation performance. The foaming agent and thermal conductive agent are used to adjust thermal conductivity of the material. The present invention is also directed to a process method of making a flame retardation thermal interface material.

  • Publication number: 20200370302
    Abstract: The present invention is directed to a building panel having a laminate structure comprising a cellulosic layer; and a topcoat layer that is substantially impervious to ambient moisture. The topcoat layer comprises a sealant sub-layer, an intumescent sub-layer comprising an intumescent composition, and the sealant sub-layer is positioned between the cellulosic layer and the intumescent sub-layer such that the intumescent sub-layer is separated from the first major surface of the cellulosic layer by the sealant sub-layer. The resulting building panel exhibits superior flame retardancy resulting in a Class A fire rating, according to ASTM E-84.
