Abstract: Methods and systems for forming a thin-layer moisture-resistant fiber composite material involve pressing a mixture of fibers and resin between a pair of heated dies at least one of which includes a working surface coated with a hard ormosil coating including a cross-linked organically-modified silica network. The use of such coatings may yield composite sheet materials having improved surface quality, sharper edges, and greater draw angles than previously possible. Some systems for making thin-layer fiber composite materials may utilize ormosil coatings on various working surfaces of equipment coming into contact with the fiber and resin mixture, such as surfaces of machinery for mixing or conveying the mixture to the dies.

Abstract: A method to produce thin-layer lignocellulosic composites, such as wood-based doorskins, that exhibit substantial resistance to moisture is disclosed. In an embodiment, the method includes the steps of forming a mixture including a refined lignocellulosic fiber, wax, and an organic isocyanate resin. The mixture is initially pressed to form a loose mat. Subsequently, the mat is pressed between two dies at an elevated temperature and pressure to further reduce the thickness of the mat and to promote the interaction of the resin with the lignocellulosic fibers. In an embodiment, a release agent is included as part of the fiber mixture, or sprayed onto the surface of the mat. The thin-layer lignocellulosic composites of the present invention exhibit strong surface strength, high adhesiveness, and a 50% reduction in linear expansion and thickness swelling upon exposure to a high moisture environment as compared to thin-layer composites that do not include the isocyanate resin.

Abstract: In one aspect, the present invention is a thin-layer lignocellulose composite having increased resistance to moisture. The thin-layer lignocellulosic composite includes a mixture of no more than about 95% by weight of a lignocellulosic fiber and at least about 5% by weight of an organic isocyanate resin. The mixture further includes short fibers and a release agent that does not interfere with subsequent processing of the thin-layer lignocellulosic composite. The mixture is pressed between two dies at an elevated temperature and pressure and for a sufficient time to form a thin-layer composite of predetermined thickness, and to allow the isocyanate resin to interact with the lignocellulosic fiber and short fibers such that the resultant thin-layer composite has a predetermined resistance to moisture.
Abstract: A polymer casting formulation for producing molded polymeric structural members comprises a liquid mixture that contains a polyisocyanate component comprising at least two polyisocyanates; and an isocyanate-reactive component comprising at least two isocyanate-reactive compounds, which formulation cures to form a polyurethane. Methods of using the casting formulation to produce molded polymer structural members and the structural members that are produced by such a method are also described.

Abstract: A latch for use in a window comprising a bottom sash mounted in a window frame, the latch comprising a housing comprising a top wall, a bottom wall, a pair of opposed sidewalls and a rear wall. A top edge of the rear wall and a rear edge of each sidewall define a rear aperture. A front edge of the top wall, the bottom wall and each of the sidewalls defines a front aperture, the front aperture and the rear aperture opening into a bolt cavity defined by the housing. A bolt is slidably received by the housing, the bolt comprising a body with a front portion and a rear portion. The body is slidably received in the bolt cavity between a first position in which the front portion of the bolt is extended outwardly through the front aperture and the rear portion of the body engages an outer surface of the housing, and a second position in which the rear portion is disengaged from the housing. The rear portion of the bolt extends outwardly through the rear aperture in both the first and second positions.

Abstract: A composite mixture for making a thin-layer composite product, such as a door skin, which includes cellulosic fibers, at least 1% by weight noncellulosic fibers, such as glass fibers, and at least 1% by weight of an isocyanate resin, and methods for making them. The noncellulosic fibers may be individualized before they come in contact with the resin.
