摘要:
A sheet of plastic material is provided adapted to be assembled with a glass substrate to form an asymmetric pane. The plastic material sheet contains at least two films, where one film is an adhesive film intended for contact with the glass substrate and a second film is adjacent to the adhesive film, at least the adjacent film containing at least one organosilane coupling agent.

A transparent, smooth and cross-linked polyurethane resin sheet prepared from a reaction-curable composition which comprises a high molecular weight polyol mixture (A) comprising a polyester polyol and/or a polycarbonate polyol, as its main components, and containing a diol and a trivalent or higher valent polyol, the average hydroxyl value of the mixture being from 40 to 120, and the equivalent ratio of (the trivalent or higher valent polyol)/(the diol) being from 0.1 to 0.8, a substantially bivalent chain extender (B) in an amount of from 1.9 to 6.0 equivalents per equivalent of the polyol mixture (A), and a substantially bivalent alicyclic or aliphatic polyisocyanate compound (C) in an amount of from 0.8 to 1.2 equivalents per equivalent of the sum of the polyol mixture (A) and the chain extender (B), as its main components.
摘要:
A method for the manufacture of a laminated glass assembly comprising (1) a monolithic or laminated glass and/or plastic support having an glazed edge, and (2) a plastic sheet comprising at least one layer of polyurethane in contact with the surface having the glazed edge is disclosed. In the invention, at least one of the two contact surfaces of the glazed edge with the polyurethane layer is treated, before the assembly of the support with the plastic sheet on an area corresponding essentially to the glazed edge, by the deposit of a primer comprising a reactive mixture having free NCO groups. The free NCO groups are capable of reacting with the glazed support and with the plastic sheet and of forming cross-linking bonds with the other components of the primer at the time of the heat cycle of the subsequent assembly. The plastic sheet is the assembled with the support, and the glass undergoes a heat cycle which enables the reaction of the primer and the definitive peripheral adhesion of the glass.
摘要:
A high optical quality polyurethane layer is manufactured by reactive pouring or reactive spraying of a reaction mixture comprising an aliphatic isocyanate component and a polyol component followed by a polymerization comprising the passage of the layer through a catalytic atmosphere containing at least one tertiary amine.
摘要:
The invention relates to a molded window glass intended to be installed by gluing it into a window opening, especially a window opening in a car.The molded profile has at least one reactive surface comprising free OH groups which can subsequently react with the strip of adhesive used for installation of the window glass in the window opening by gluing.
摘要:
A process for producing a multi-layer film having a plurality of synthetic resin layers laminated on a releasable flat substrate by casting, which comprises firstly forming on the substrate a synthetic resin layer having adhesive or sticking properties, and then casting and curing on the synthetic resin layer having adhesive or sticking properties at least one kind of reaction-curable resin raw material mixture substantially free from a solvent to form at least one cured synthetic resin layer, so that the uppermost layer is composed of a cured synthetic resin superior in surface properties to its adjacent layer. Further, surface defects transferred from the substrate to the adhesive layer are substantially eliminated by a subsequent lamination step.
摘要:
A process for coating a transparent article of high optical quality, which comprises spraying a polymerizable reaction mixture of reaction components on the transparent article to form a homogeneous coating layer of high optical quality, wherein the mixture of reaction components is sprayed by high-speed centrifugal spraying; and polymerizing the resultant coating layer.
摘要:
An adhesive layer used in the manufacture of laminated glasses. The layer comprises a cold polymerizable polyurethane formed from an isocyanate component comprising a monoisocyanate with a double ethylene bond and from a polyol component and at least one polymerization initiator.
摘要:
The invention relates to a product which is at least partly transparent and of high optical quality, equivalent to that of a glass window, which can be approved as a motor-vehicle window according to the various standards in force, and having a plastic core coated with a skin comprising at least one plastic film coated with a scratch-resistant layer; it also relates to a process for manufacturing this product and to the application of the latter as a body element, part of which forms a window, for example for motor vehicles.
摘要:
The invention concerns an essentially flat plastic product, at least partly transparent and whereof one part at least of the external surface consists of added overmoulded plastic material. The invention also concerns two methods for making said product, using injection moulding technique and the use of said product as glazing for transport vehicles or buildings.
