The invention is directed to an aqueous binder composition for mineral fibers.

Aqueous binder composition

A method of growing plants in a coherent growth substrate product is provided and includes: providing at least one coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition; positioning one or more seeds, seedlings, cuttings or plants in contact with the growth substrate product; and irrigating the growth substrate product. The aqueous binder composition prior to curing includes a component (i) in the form of one or more oxidized lignins, a component (ii) in the form of one or more cross-linkers, and a component (iii) in the form of one or more plasticizers.

Method of growing plants

The present invention relates to a method of draining water comprising the steps of:

Method of draining water

A method of growing plants in a coherent growth substrate product can comprise: providing at least one coherent growth substrate product comprising man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde; positioning one or more seeds, seedlings, cuttings or plants in contact with the growth substrate product; and irrigating the growth substrate product. The aqueous binder composition prior to curing can comprise; a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins; and a component (ii) in form of one or more cross-linkers.

A façade system for a building, in particular an External Thermal Insulation Composite System (ETICS), comprises a thermal and/or acoustic insulation, consisting of at least one insulation element being a bonded mineral fibre product made of mineral fibres, preferably stone wool fibres, and a cured aqueous binder composition, whereby the insulation element is fixed to an outer surface of the building by mechanical fastening elements and/or an adhesive, covered with a rendering, and whereby the aqueous binder composition prior to curing comprises a first component in form of one or more oxidized lignins, a second component in form of one or more cross-linkers, and a third component in form of one or more plasticizers, whereby the insulation element has a bulk density between 70 kg/mand 150 kg/m.
