A transparent coating for windows or other transparent substrates made of glass or synthetic resin, consisting of a flexible elastic polyurethane, serves as a shatterproofing coating for substrates made of silicate glass or as a coating improving the scratch resistance of substrates made of synthetic resin. To reduce or prevent the formation of a deposit of moisture on the surface of the coating, the polyol component of the reaction mixture for preparing a coating pursuant to the invention consists of a difunctional sulfonated polyether polyol containing approximately 1 to 10% of OH groups by weight and a trifunctional polyol containing approximately 8 to 12% of OH groups by weight and having an average molecular weight of approximately 400 to approximately 1000 g/mole.

Transparent coating of flexible, elastic polyurethane for transparent

A transparent adhesive coating or film based on polyurethane. A polyurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one bifunctional chain-lengthening agent containing an aromatic nucleus.

Polyurethane-based adhesive coating or film, and use of same in

A transparent adhesive coating or film based on polyurethane. The coating or film comprises a polurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one chain-lengthening agent which is a product of the reduction of dimeric acid to a diol. The adhesive coating or film is employed in laminated panes of glass and/or plastic material.

Glazing laminates and method of making same

The invention relates to a transparent, antifogging coating or film comprised of a plastic material, which coating or film may be employed as an external layer in a laminated pane. The invention transparent coating or film is a highly elastic, three-dimensionally crosslinked layer comprised of at least one surface active agent disposed within its crosslinked structure.

A multilayer plastic foil for use as a window. The foil includes a core and a pair of cover layers and includes features of flexibility, durability, scratch resistance, among others, for application of the window for a convertible top vehicle. The pane may include a heating capability.

Flexible, transparent pane for use as a window

In the manufacture of plastic articles, particularly thermoset plastic sheets having good optical properties, by a process which involves forming the article on a surface to which the article tends to adhere, numerous and important advantages are realized by using, as a release agent which facilitates removal of the article from the surface, a salt of an addition product of a lower alkylene oxide which can be prepared by the fixation of a lower alkylene oxide on an organic material having a group reactive therewith, such as, alcohols, acids and amides, and subjecting the resulting product to esterification and neutralization.

Process utilizing release agent

The invention relates to safety glass comprising a silicate glass layer and a coating of an elastic material forming a protective layer on at least one side of said glass layer. The coated side has a delineated area formed of a relatively hard, scratch-resistant material to which a label may be removably attached. Thus, when the label is removed, the protective layer is not damaged.
