Abstract: A system of connected elements for a motor vehicle includes: a first element which has at least one depression on a surface; a second element which is arranged on the first element in such a manner that a surface of the second element and the depression of the first element form a cavity; a filling opening which forms an access to the cavity; and an adhesive which at least partially fills the cavity and thereby adhesively bonds the first element to the second element.

Abstract: The present invention comprises methods for the pretreatment of substrates, including without limitation, metal or glass surfaces, with activators of reduced VOC content. Preferred embodiments of the invention comprise activators containing methyl acetate as a solvent, at least one adhesion promoter, and a luminescent agent responsive to light of specific wavelengths. In some embodiments, without limitation, an activator composition of reduced VOC content and also comprising a luminescent agent is applied to a substrate before application of additional adhesives or paints, and the substrate is examined under a controlled light source as required to excite the luminescent agent. The luminescent agent in the activator composition appears distinctly where the activator has been applied to the surface, allowing one to detect whether the activator has been properly applied.

Abstract: A method for installing a constrained layer damper on a product of manufacture is disclosed. The method includes applying a layer of first polymeric material to a substrate of the product, wherein the first polymeric material is visco-elastic when solidified. Then, a second layer of polymeric material, which is stiff when solidified, is applied to the first polymeric material such that said first polymeric material is constrained between the second polymeric material and the substrate of the product. At least one of the layers of polymeric materials is dispensed in fluid form during the manufacture of the product from a bulk source of fluid material. The polymeric materials are chosen such that they do not require the application of heat above room temperature to solidify.
