The present invention provides polyurethanes including a reaction product of components including: (a) at least one isocyanate functional prepolymer including a reaction product of: (1) about 1 equivalent of at least one polyisocyanate; and (2) about 0.01 to about 0.5 equivalent of at least one polycarbonate polyol; and (b) about 0.01 to about 1 equivalent of at least one branched polyol having at least 3 hydroxyl groups; compositions, coatings and articles made therefrom and methods of making the same.

A laminate structure has first and second polymer layers with a glass layer between the first and second polymer layers. The glass layer is fused to the first and second polymer layers. The glass layer is encapsulated by the first and second polymer layers, and the glass layer is in compression.

A preparation method of an energy-saving window film used for insulating glass sputters metals, metal oxides and nitrides on a surface of a high-strength base film in a layer-by-layer manner by a magnetron sputtering process, so as to reduce an infrared emissivity of film layers and effectively block an infrared transmission without affecting a daylighting field of vision; by coating a modified polyurethane acrylate protective layer on a surface of a low radiation layer, an oxidation resistance of the coating is improved; an installation adhesive layer provides an adhesion of the film to the glass, which can enhance the impact strength of the glass and play the role of safety and explosion-proof. The energy-saving window film is applied to the insulating glass with multiple functions such as impact resistance, lightness, energy-saving heat preservation, oxidation resistance, etc., which extends the overall service life of the insulating glass.

The disclosure includes multi-layered panels (10, 60, 204) including exterior layers of glass (12, 44) and interior layers of urethane (20, 36) and at least one layer of polycarbonate (16) between the urethane layers (20, 36) that result in enhanced shatter resistance within panels (10, 60, 204) that weigh between about 4.1 and 4.6 pounds per square foot. The panels (10, 60, 204) include an insertion tab (23, 61, 23) of the polycarbonate layer (16) that enhances performance of the panel (10). Reinforced passageways (70, 200, 300), such as doors and windows of schools, hospitals and other public and private buildings, are disclosed using the multi-layered panels (10, 60, 204) with the insertion tab (23, 61, 23).

The present invention relates to transparent laminated panes for security applications, which comprise a laminate made up of transparent layers of a compartmentalized construction, with two blocks separated from one another by a gas-filled intermediate space, wherein the layer of the second block, which is in contact with the gas-filled intermediate space, comprises transparent ceramic, and relates to the use thereof for security and/or protection applications for panes or windows in civilian and military areas.

A functional glass, an artificial glass laminate, and a self-contained window unit formed therefrom can include functional performance layers such as an electrochromic assembly in one layer, and a photovoltaic assembly in another layer. The photovoltaic assembly may include a polymeric interlayer having transparent photovoltaic cells disposed therein, or a thin film of organic photovoltaic cells, the photovoltaic cells providing electrical power to the electrochromic assembly. A first layer of glass and a second layer of glass separated by a gap may be disposed between the electrochromic assembly and the polymeric interlayer. The glass, laminate and window unit are optically clear.
