Abstract: A two-component composition, containing at least one silane-group-containing polymer that is liquid at room temperature, at least one epoxide liquid resin, at least one polyetheramine, and at least one aminosilane or mercaptosilane. The composition has low odor, cures quickly and without blistering at room temperature, and, when cured, forms a tough elastic material of high strength, high adhesive force, and good thermal resistance that has no tendency toward yellowing or substrate discoloration. The composition is excellently suitable as a tough elastic adhesive for structural adhesive joints in the field of construction and in industrial production.

Abstract: A method of producing a laminate, wherein a wood body is provided, a curable composition in the liquid state is applied thereto, and the composition cures, wherein the composition contains at least one organic binder and at least 80% by weight of mineral fillers, based on the overall composition. The method enables permanent bonding of wood bodies and compositions that are based on organic binder and have a high content of mineral fillers. The laminates obtained from the method are comparatively lightweight, stable and durable, and are particularly suitable as sustainable components in building construction, especially as a roof element.

Abstract: A two-component polyurethane composition containing at least 55% by weight of polybutadiene polyols based on the total amount of all polyols having an average molecular weight of at least 500 g/mol, and at least one latent hardener, where the ratio of the number of reactive groups in the latent hardener to the number of OH groups present is in the range from 0.02 to 0.4. The composition has a long open time, blister-free curing, a very low glass transition temperature, high elasticity and surprisingly high strength which is very constant over a wide temperature range. Furthermore, it has very good adhesion to metallic and nonmetallic substrates, causing barely any stress cracks on glassy thermoplastics.
