The present invention relates to a production method for an aerogel laminate including a support, and an aerogel layer disposed on the support and having a thickness of 200 μm or less, the method comprising a step of washing a wet gel laminate including the support and a wet gel layer disposed on the support by a roll-to-roll scheme.

Two-component solventless polyurethane adhesive compositions comprising an isocyanate component and an isocyanate-reactive are disclosed, the compositions comprising an isocyanate component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and, optionally, a bio-based polyol. Methods for forming laminate structures are also disclosed, the methods comprising forming an adhesive composition by mixing an isocyanate adhesive component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive adhesive component comprising a hydroxy-terminated polyurethane resin, a polyether polyol, a phosphate ester adhesion promoter, and optionally, a bio-based polyol, applying the adhesive composition to a surface of a first substrate, and bringing a surface of a second substrate into contact with the adhesive composition on the surface of the first substrate, thereby forming the laminate structure. Laminate structures are also disclosed.

The invention relates to a hollow board material comprising a first sheet and a second sheet. A first and a second lath are arranged in parallel between the first sheet and the second sheet along opposite edges of the hollow board material. The first lath and the first sheet are attached to each other by means of a first metal gripping lamina which at least partly covers the first lath. The second lath and the first sheet are attached to each other by means of a second metal gripping lamina which at least partly covers the first lath. Optionally, the first lath and the second sheet are attached to each other by means of a third metal gripping lamina and optionally the second lath and the second sheet are attached to each other by means of a fourth metal gripping lamina. The metal gripping laminas have a first face and a second face which are opposed to each other. Each face comprises a plurality of sharp projections extending substantially perpendicular therefrom and into the laths or the sheets respectively. The metal gripping laminas thereby provides a hollow board material and increases the bending strength of the hollow board material. The invention further relates to a furniture comprising said hollow board material and method for producing said hollow board material.
