This invention generally pertains to a composite building material comprising a lightweight core with a thin fiber cement facing on one side of the core and a second facing material on the other side. The fiber cement facing that is used on at least one of the faces of the building material is 3/16' or less, more preferably 1/8' or less. The green fiber cement facing is preferably formed by a slurry-dewatering process to form a sheet that is in a plastic, uncured, state prior to manufacture of the composite. The composite building material is assembled in an uncured state and then cured.

Composite building material

An encapsulant material includes a layer of metallocene polyethylene disposed between two layers of an acid copolymer of polyethylene. More specifically, the layer of metallocene polyethylene is disposed adjacent a rear surface of the first layer of the acid copolymer of polyethylene, and a second layer of the acid copolymer of polyethlene is disposed adjacent a rear surface of the layer of metallocene polyethylene. The encapsulant material can be used in solar cell module and laminated glass applications.

Disclosed are weatherable multilayer articles comprising (i) a coating layer comprising a block copolyestercarbonate comprising structural units derived from at least one 1,3-dihydroxybenzene and at least one aromatic dicarboxylic acid, (ii) a second layer comprising a polymer comprising carbonate structural units, (iii) a substrate layer comprising a polypropylene, and (iv) at least one adhesive layer comprising the reaction product of an amine-functionalized polypropylene and a polyurethane, wherein the coating layer is in contiguous contact with the second layer, and the adhesive layer is in contiguous contact with the second layer and the substrate layer. Also disclosed is a method for making the multilayer article.

Weatherable multilayer articles and method for their preparation

A windshield for a head-up display system has a pair of opposing major surfaces that are nonparallel to one another in selected areas Light rays directed toward the nonparallel area of the windshield are reflected from the outer and inner major surfaces of the windshield and directed toward the eye of the observer as parallel or superimposed light rays to eliminate ghost images when viewing images projected by the head-up display system through the windshield The interlayer blank utilized to make the windshield has a non-uniform thickness profile with a tapered thickness positioned in the selected areas of the windshield

The present inventions teaches an optically transparent film or sheet which is greater than or equal to 0.5 mm in thickness and includes an extrudable ionomer resin which comprises a carboxylic acid polymer and which is essentially free of amines. The ionomer resin film can be used alone or in a lamination with polycarbonate or glass. In certain embodiments, it is preferable to partially or fully neutralize the acid polymer with a metal cation.

Ionomer resin films and laminates thereof

A laminated glazing unit having outer sheets of glass or plastic and at least one resinous interlayer bonding the outer layers together. The unit is provided with an attachment member embedded in the interlayer free from contact with the outer sheets for attachment to a support structure.

Laminated glazing unit

A fire resistant and impact resistant transparent laminate comprising at least two spaced parallel sheets of transparent material selected from the group consisting of ceramic glass and polymeric material, at least one optically transparent fluorocarbon polymer modified with polar groups, at least one optically transparent glass or resinous inner layer between said parallel sheets, and at least one layer of an optically transparent intumescent gel on at least one side of said inner layer.

Fire resistant transparent laminates

A process is disclosed for producing multi-layer laminates of glass and plastic of the type subject to nonsymmetrical thermal shear stress, such as flat or curved glass-plastic laminates or curved glass-plastic-glass sandwiches. Use of difunctional silane-treated glass and an aliphatic polyether polyurethane interlayer allows curing at temperatures low enough to minimize shear stresses which tend to cause delamination or shattering of the thin layer of glass in the finished part. The interlayer of aliphatic polyether polyurethane can be replaced by cured-in-place polyurethane having a polyether backbone, allowing processing at even lower temperatures.
