Abstract: The addition of pulverulent monosaccharides, disaccharides or oligosaccharides to plastisols based on pulverulent organic polymers and plasticizers results in plastisols with good adhesion properties on a large number of substrates employed in automobile construction. These plastisols are distinguished by good adhesion properties and a high resistance to ageing, and can be employed in automobile construction both in shell construction and in the lacquering line and in the trim shop for adhesive, sealing and coating tasks.

Abstract: The use of benzoate plasticizers in two-component insulating glass adhesives/sealants based on polysulfide polymers or polymercaptan polymers enables simpler production due to the low viscosity thereof. Improved miscibility of the two components and an improved rate of curing are observed. In addition, the use of phthalate plasticizers, which may possibly cause an endocrinal effect in humans and animals, is avoided.

Abstract: The present invention relates to phenol terminated or aminophenyl terminated products and compositions containing the same. The phenol-terminated or amino-terminated products are produced by reacting a stoichiometric excess of a carboxylic anhydride or dianhydride with a diamine or polyamine, and reacting the excess carboxylic anhydride groups or carboxylic acid groups with at least one polyphenol or aminophenol to form the phenol-terminated or aminophenyl-terminated products. The compounds are preferably utilized in adhesive compositions.

Abstract: Monoesters of fatty acids containing at least 12 carbon atoms may replace a considerable percentage of conventional plasticizers based on phthalic acid esters, alkyl sulfonic acid esters of phenol or other known plasticizers in plastisol compositions. The methyl and/or ethyl esters of fatty acids of renewable fats and oils, such as tall oil fatty acids, rapeseed oil fatty acids, linseed oil fatty acids or safflower oil fatty acids, are preferably used for these secondary plasticizers. These plastisols are preferably used as adhesives, sealing materials or coatings in automobile construction.

These compositions optionally contain fine-particle thermoplastic polymers as an additional component. The compositions are suitable for use as acoustically damping adhesives, sealing compounds or coating compositions.

Abstract: The invention relates to a process for recycling cured or partly cured polysulfide and/or polymercaptan compositions. Recycling is carried out in a non-volatile liquid with addition of a depolymerizing agent, preferably a sulfur-containing vulcanization accelerator known from rubber technology. The depolymerisate may be added to the curing component of two-component polysulfide and/or polymercaptan adhesives/sealants or coating materials in large quantities without any significant effect on its stability in storage or curing characteristics.

Abstract: Heat-curing, expanding mouldings based on solid polybutadiene rubber and vulcanization systems free from elemental sulfur are distinguished by the following advantageous properties: in the uncured state in which they are supplied, they have minimal rubber-elastic resilience and are readily formable. During the curing process, no unpleasant odors are given off and, after curing, a soft and elastic foam with a continuous outer skin is formed.

Abstract: The invention is a device and a method for combining at least two fluid media. The device comprises a flow region (1) which is attached to and/or formed with an opening of a first chamber (2) and which is designed to accommodate the fluid medium coming from the first chamber and to transport it to the outlet (3) of the flow region (1) which is preferably followed by a mixing zone. A second chamber (9) designed to be filled with a second fluid medium is connected to the flow region and/or to the first chamber through at least one first opening element (inlet opening) (11) for diverting part of the first fluid medium from the first into the second chamber. The second chamber is provided with at least one second opening element (second opening) (12) opening into or adjoining the flow region (1) for discharging the second fluid medium displaced into it by the first fluid medium. Several first chambers (2) or second chambers (9) may be provided.

At one and the same time, they perform a sealing function, damp acoustic vibration and stiffen the hollow structures to a considerable extent.

Abstract: A Process for Joining Plastic Moldings Plastic moldings can be joined with one-component or two-component adhesives, the connecting joint being spanned by metal strips. The metal strips are at least partly embedded in the adhesive layer. This process is particularly suitable for repairing damaged plastic moldings, more particularly automobile parts, for example fenders. The moldings repaired by the process according to the invention are restored to their original performance properties, more particularly dimensional rigidity, impact strength and appearance. In the event of scrapping, the moldings thus repaired are fully recyclable by conventional methods.

The plastisols are suitable for use in motor vehicle construction as underseal material, as an adhesive for hood lining, as a compound for grille protection or as a spot-welding paste, and in the packaging products industry as a sealing compound for container closures or as a seam seal or as a flange-joint adhesive for tin cans.

Abstract: Plastisol compositions based on vinyl chloride/vinyl acetate copolymers produced by suspension polymerization have a low viscosity, even with low polymer-to-plasticizer ratios, so that they may be used for plastisol formulations suitable for airless spraying. The compositions are stable in storage and show good gelation properties. Coatings based on these plastisols have a good noise-damping effect, even with high vinyl acetate contents.
