Abstract: A sprinkler including a housing having an outlet aperture covered by a shut-off valve, a heat-sensitive destructible element, and an actuation monitoring device. The monitoring device is configured as a current-conducting coating that is applied to a surface of the element. The coating has terminals for connecting to a circuit of a sprinkler status monitoring unit. The element is configured as a hermetic glass bulb filled with a liquid that boils at a sprinkler activation temperature. The terminals are located at one end of the heat-sensitive destructible element and are connected to the coating using clamps that encircle the surface of the element. The coating is applied to the surface using sputter deposition. The applied coating is electrically conductive and allows the bulb to be heated to a boiling temperature of the liquid with which the bulb is filled, while feeding voltage from the sprinkler status monitoring unit.

Abstract: The invention relates to a process for increasing the proportion of components which are non-volatile under processing conditions, in basecoat compositions containing predominantly organic diluents or solvents, for the production of multicoat finishes, preferably metallic finishes. In the process according to the invention, up to 10% by weight of the components which are volatile under processing conditions, are replaced by an aliphatic polyether or by mixtures of aliphatic polyethers, the aliphatic polyethers having a mean molecular weight of not less than 300, containing not less than one hydroxyl group per molecule and being liquid under normal conditions.

Abstract: The invention relates to a process for the production of a multicoat coating of the basecoat/clearcoat type using a water-dilutable basecoat composition. The process comprises a basecoat composition which contains 0.1 to 4.0% by weight, based on the binder solids, of xanthan gum and 5 to 80% by weight, based on the binder solids, of crosslinked polymeric microparticles prepared from polyester polyols and polyisocyanates.

Abstract: Two-component polyurethane sealants, in particular for the direct glazing of motor vehicles, comprising (A) a pasty polyurethane component containing a polyurethane prepolymer having free isocyanate groups, and a curing agent, and (B) a pasty water-containing component, component (A) containing a blocked curing agent which can be liberated by water, and component (B) containing the water, reversibly bonded to a carrier substance which liberates the watering a delayed manner after components (A) and (B) have been mixed.

Abstract: The invention relates to water-thinnable baking paints, the use thereof as filler material and intermediate stone chip resistant coat as well as a process for painting motor vehicle bodies.The water-thinnable baking paints comprise as binders a combination of(I) 20 to 70% by weight of a water-thinnable polyurethane resin with an acid value of 15 to 35,(II) 20 to 70% by weight of an epoxy resin-modified water-thinnable polyester which can be prepared by reacting a polyester (A) with a molecular weight (number average) below 2000, an acid value of 35-240 and a hydroxyl value of 56-320, with 0.3 to 1.

Abstract: The invention relates to dispersions which are obtainable from sheet silicates, a protective colloid and an aqueous dispersant and are suitable for the incorporation of sheet silicates into water-dilutable coating compositions. The dispersions according to the invention are obtainable using poly(propylene oxide) as the protective colloid, and the poly(propylene oxide) contains no hydrophobic terminal groups, has on average at least one hydroxyl group per molecule and may optionally contain up to 40% by weight of --CH.sub.2 --CH.sub.2 --O-- units.

Abstract: The homogeneity of highly reactive polycondensates is improved in a process involving batch operations in a reactor, followed by extrusion and then cooling by a coolant to the point of solidification after which the polycondensates are milled and removed. The cooling is carried out with a low-boiling liquified gas.
