Claims28
A mineral fiber product, wherein the product comprises mineral fibers in contact with a binder resulting from curing an aqueous binder composition which comprises:
- a component (i) in the form of one or more oxidized lignins;
- a component (ii) in the form of one or more cross-linkers;
- a component (iii) in the form of one or more plasticizers.
A method of producing a bonded mineral fiber product, wherein the method comprises contacting mineral fibers with an aqueous binder composition and curing the binder composition, the binder composition comprising:
- a component (i) in the form of one or more oxidized lignins;
- a component (ii) in the form of one or more cross-linkers;
- a component (iii) in the form of one or more plasticizers.
An aqueous binder composition, wherein the composition in its cured state is capable of binding mineral fibers to afford a bonded mineral fiber product, and comprises:
- a component (i) in the form of one or more oxidized lignins;
- a component (ii) in the form of one or more cross-linkers;
- a component (iii) in the form of one or more plasticizers.
