The present disclosure relates to a method for producing rigid polyurethane foam composite elements, including at least one outer layer and a rigid polyurethane foam layer, by mixing (a) polyisocyanates with (b) compounds having at least two hydrogen atoms reactive with isocyanate groups, (c) optionally flame retardant(s), (d) blowing agent, (e) catalyst, and (f) optionally auxiliaries and adjuvants to form a reaction mixture, applying the reaction mixture to the outer layer, and curing it to form the rigid polyurethane foam. The present disclosure further relates to a rigid polyurethane foam composite element obtainable by such a method.

Method for producing polyurethane hard foam composite elements using Mannich polyols

Provided herein is a facade for a building, made up of composite elements, the composite elements respectively having an inner cover layer, a polymer foam layer as the core and an outer metallic cover layer, and are fastened to a supporting structure. Each composite element has at least two fastening regions, in one fastening region the composite elements are immovably connected to the supporting structure and in the other fastening regions the composite elements are displaceably connected to the supporting structure, or the composite elements resting with the ground-facing side on a mounting and all fastening regions displaceably connected to the supporting structure.

Facade for a building, constructed from composite elements

An apparatus for application of liquids to a continuously conveyed outer layer having a rotating plate which is horizontal and parallel to the outer layer or with a deviation of up to 15&#xb0; from horizontal, wherein a liquid applied to the rotating plate is ejected centrifugally from the rotating plate via rotation and then, via gravity, passed onto the outer layer below the rotating plate, is provided.

Method for the production of composite elements based on isocyanate-based foams

The invention provides a method for the production of composite elements composed of at least one outer layer a) and a thermal insulation material b), where between the outer layer a) and the thermal insulation material b) an adhesive c) has been applied, the outer layer a) being moved continuously, the thermal insulation material b) being applied to the outer layer a) and, if appropriate, a further outer layer a) being applied to the thermal insulation material b), and the adhesive c) being applied to the thermal insulation material b) or to the outer layer a), which comprises applying the adhesive c) by means of a rotating flat body which is mounted horizontally or with a slight deviation from the horizontal, of up to 15&#xb0;, preferably parallel to the outer layer a) or to the thermal insulation material b).

Method for the production of composite elements based on mineral or organic thermal insulation materials with the aid of an adhesive

The invention relates to a process for production of composite elements composed of at least one outer layer a) and of an rigid isocyanate-based foam b), where between the outer layer a) and the rigid isocyanate-based foam b) an adhesion promoter c) has been applied, and where the outer layer a) is continuously moved and the adhesion promoter c) and the starting material for the rigid isocyanate-based foam b) are applied successively to the outer layer, which comprises applying the adhesion promoter c) by means of a rotating plate which has been installed horizontally or with a deviation of up to 15&#xb0; from horizontal, preferably parallel to the outer layer.
