Abstract: The invention is directed to an aqueous binder composition made of a mixture of i) a phenol-urea-formaldehyde binder (PUF binder), and ii) a protein binder comprising at least one protein and iii) at least one cross-linker selected from phenol containing compounds. The aqueous binder composition is suitable for producing a mineral fibre product by contacting mineral fibres with the aqueous binder composition and curing the binder.

Abstract: The invention relates to an aqueous binder composition for mineral fibers comprising at least one hydrocolloid.

Abstract: The invention relates to a mineral wool product comprising mineral fibers bonded by a cured binder wherein the binder in its uncured state comprises at least one protein and at least one enzyme.

Abstract: The invention is directed to a formaldehyde-free binder composition for mineral fibres comprising at least one phenol containing compound, at least one protein and at least one divalent metal cation M2+ containing compound.

Abstract: A fire-protecting insulation product has air-laid mineral wool fibres and a binder. The binder is the result of curing a binder composition comprising at least one hydrocolloid. The product further comprises a particulate endothermic material.

Abstract: A method of bonding together surfaces of two or more elements, whereby at least one of the two or more elements is a mineral wool element, said mineral wool element(s) being bound by a mineral wool binder, comprises the steps of providing two or more elements; applying an adhesive to one or more of the surfaces to be bonded together before, during or after contacting the surfaces to be bonded together with each other, curing the adhesive, wherein the adhesive comprises at least one protein; at least one phenol and/or quinone containing compound, and/or at least one enzyme.

Abstract: The present invention relates to an aqueous binder composition for mineral fibers comprising—at least one hydrocolloid, —at least one fatty acid ester of glycerol.

Abstract: The invention relates to a method of bonding together surfaces of two or more elements, whereby at least one of the two or more elements is a mineral wool element, said mineral wool element(s) being bound by a mineral wool binder, the method comprising the steps of providing two or more elements; applying an adhesive to one or more of the surfaces to be bonded together before, during or after contacting the surfaces to be bonded together with each other; curing the adhesive, wherein the adhesive comprises at least one protein; at least one phenol and/or quinone containing compound, and/or at least one enzyme.

Abstract: A method for producing a mineral wool product includes contacting mineral fibres with a formaldehyde-free binder composition for mineral fibres.

Abstract: A formaldehyde-free binder composition is for mineral fibres.

Abstract: The present invention relates to a method of providing thermal and/or acoustic insulation to a structure, comprising the steps of: providing a substrate which comprises fibres; applying the substrate to the structure; blending the substrate with a binder composition before, during or after application of the substrate to the structure; allowing curing of the binder composition after the substrate and the binder composition have been applied to the structure; wherein the binder composition comprises at least one hydrocolloid. The present invention also relates to an insulated structure obtainable by said method.
