A pasty single component polyurethane adhesive is provided. The NCO terminated polyurethane prepolymer is substantially linear, contains from 2.0% to 8.0% based on the weight of the prepolymer, of highly disperse silica and up to 10% by weight, based on the weight of the prepolymer, of additives. The one component adhesive has an Expressed Volume of at least 2,000 g/min measured according to DIN EN 29048 and a Creep Resistance measure according to DIN EN 27390 below 6.0 after 5 minutes.

Single-component polyurethane adhesive

A one-pack polyurethane adhesive containing a polyisocyanate prepolymer and at least one aminoether polyol, having a molar ratio of ether groups to amino nitrogen in the aminopolyether polyol of 7 to 30.

Fast setting 1k-polyurethane glue

A polyurethane prepolymer obtainable by reacting at least one aromatic polyisocyanate having symmetrical substitution of NCO groups and at least one aromatic polyisocyanate having asymmetric substitution of NCO groups, the fraction of aromatic polyisocyanate having symmetrical substitution of NCO groups being higher than the fraction of polyisocyanate having asymmetric substitution of NCO groups, and at least one polyol having an OH functionality of more than 2.5 and at least one polyol having an OH functionality of less than 2.5.

Neutral-coloured 1K polyurethane adhesive

A method for increasing an adhesive to a substrate is disclosed which utilizes a hydrophilic, high molecular weight, nonionic polyurethane adhesive. The polyurethane adhesive is soluble in water and a 1% by weight solution of the adhesive in water at 20% has a specific viscosity of at least 0.4. The nonionic polyurethane contains the following structural units:

Method for thickening aqueous systems using hydrophilic polyurethanes

Method for forming an adhesive layer using hydrophilic polyurethanes related applications

The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500 g. The agglomerate is used in particular in the production of lump-free paste.
