The use of the dispersions for the surface-coating of metal, plastics, glass, leather and paper.

Inspection of workpieces traveling along a production line includes on-line inspection of the workpieces at an upstream inspection station to detect possible flaws without interrupting the progression of workpieces along the production line. Possible flaws in the inspected workpieces are imaged, and images of possible flaws are stored in a memory in a way that associates a stored image with the wo...

The subject of this invention is a process for the preparation of lightweight, planar molded articles, e.g. those having a thickness from 0.1 to 40 mm and having a density of 0.015 to 0.25 g/cm3, by treating porous materials, preferably open celled or flexible or semi-rigid polyurethane foams, with an effective amount of an aqueous dispersion or emulsion of organic compounds containing NCO groups ...

This invention relates to the area of coatings, and, in particular, to a surface-sealing composition for priming and topcoating substrates made from reaction injected molded (RIM) urethane, reinforced RIM urethane, and other materials which are sensitive to the organic solvents normally present in automotive primer and paint. When automotive primer and paint are applied to damaged surfaces made of...
