The invention relates to a method for mounting an edge, more particularly plastics edge, onto a material, and also to the products obtained in this way, and to the use thereof.

Jointing and/or adhesive-bonding method and products produced in this way

Adhesive bonding method and products produced thereby

At least one isocyanate-reactive monomer is reacted with an excess of molten monomeric diisocynate to produce at least one reaction product and a maximum of 0.5 wt % of free isocyanate groups. The reaction product is then mixed with at least 20 wt. %, based on the total weight of reaction product, of at least one isocyanate-terminated prepolymer which is essentially free of diisocyanate monomers and has a viscosity at 20&#xb0; C. of at least 1.500 mPa&#xb7;s, the isocyanate-terminated prepolymer having a content of free NCO groups of up to 25 wt % and containing a maximum of 0.1 wt. % of diisocyanate monomer(s) based on the weight of the isocyanate-terminated prepolymer. A polyurethane composition containing less than 0.1 wt. % of monomeric diisocyanate, based on the total weight of the resulting polyurethane composition, is produced.

Polyurethane compositions with a low content of diisocyanate monomer(s)

A self-supporting reactive hot-melt adhesive element of a reactive one-component hot-melt adhesive which is solid at room-temperature. The adhesive element comprises at least one isocyanate being solid or liquid at room-temperature; and at least one isocyanate-reactive polymer and/or resin being solid at room-temperature. Also disclosed is a process of producing said adhesive element as well as its application and use, in particular in a hot-melt adhesive bonding process.

Self-supporting reactive hot-melt adhesive element

Disclosed is a storage-stable, essentially aqueous one component dispersion, of a deactivated isocyanate and a isocyanate-reactive polymer which cross-links at low temperatures.

Storage-stable isocyanate dispersions

A one-component dispersion comprising deactivated isocyanates which cross-links already at low temperatures (lower than 70&deg; C.).
