Abstract: Described is an NCO-group-containing polyurethane prepolymer madefrom polyisocanyates and polyols derived from natural oils. The invention is characterized in that the polyol is obtained by transesterification in the presence of basic lithium compounds. Together with a tertiary amine used to accelerate the moisture curing, the storage stability is thus increased considerably. Up to 4.0 mmol of the lithium compound is used per kilogram of polyol, and 0.1 to 2.0% by wt. of the amine, relative to the total weight of the composition, is used as the accelerator. The polyurethane prepolymer is suitable not only for the production of adhesives but also for the production of foamed materials, in particular those dispensed from throw-away pressure vessels.

The handle may be moved into a position substantially parallel to the elongate receiving unit when not in use.

Abstract: An enzyme granule and means for producing the enzyme granule is presented. The enzyme granule is composed of an enzyme, a carrier material, and a coating system of 5 to 70 percent by weight fine-particle inorganic water-insoluble pigment, 45 to 90 percent by weight of a water-soluble organic substance having a melting point of from 40 to 70° C., and 0 to 30 percent by weight of a flow improver. The granule can be produced by mixing an aqueous enzyme liquid with an inorganic or organic carrier material to form an enzyme compound, extruding the enzyme compound, spheronizing the extrudate, and applying an outer coating layer of the coating system listed above to form an enzyme granule having a mean particle size of 0.8 to 1.4 millimeters. The coated enzyme granule has increased storage stability, even coloration, reduced odor, and releases enzyme activity quickly in water. The enzyme granule is useful in solid detergents.

Abstract: The problem addressed by the invention was to provide a foam regulator system containing silicone and/or paraffin and bis-fatty acid amide which would have a low viscosity, which could be handled at low temperatures and which would have a low percentage content of non-foam-regulating ingredients. This problem was largely solved by an aqueous foam regulator emulsion containing 16% by weight to 70% by weight of active foam regulator based on paraffin wax and/or silicone oil, 2% by weight to 15% by weight of nonionic and/or anionic emulsifier and no more than 80% by weight of water. The foam regulator emulsion is preferably used for the production of partiulate foam regulator granules for use in detergents.

Abstract: The joint reinforcement member for a hollow structure of an automotive vehicle has a carrier portion with an outer surface. The carrier portion has a base portion with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis. The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality extensions extending from a base portion that correspond to the hollow structure a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive layer is bonded to the structural member.

The material outlet opening only releases the flow of the component (2) after the piston (4) has been moved past the material outlet opening into the end position (4′) by the expressing pressure. The device can be used with a conventional applicator for one-component adhesives, sealants or coating materials to provide the addition of a second component.
