Abstract: An aqueous coating composition is provided which reflects light, especially UV radiation, and can be colored as desired. It is prepared from a synthetic resin dispersion and inorganic pigments having a particle size ranging between 7 and 10 nm, with the exception of carbon black.

Abstract: A method of producing electrically conductive plastics materials from polymers and electrically conductive particles wherein an aqueous dispersion of polyacrylate, such as a thermally cross-linkable copolymer based upon ethyl acrylate, or a polyisobutylene is mixed with an aqueous dispersion of electrically conductive particles such as noble metals, non-metallic materials coated with noble metals, or carbon, and the resulting mixture is spread out in a thin layer on a support, whereafter the water is evaporated at a temperature above the softening of the plastics material.

Abstract: This invention relates to electrically conductive foam moulding manufactures from electrically conductive polystyrene beads containing blowing agent.

Abstract: This invention relates to a process for preparing organosilicate polymers by reaction of a water glass solution with a compound having at least two isocyanate groups. The reaction is carried out in the presence of a zwitterion compound acting as catalyst and optionally in the presence of propellants and/or water glass hardening agents, the zwitterion compound having in the molecule at least one group with positive charge, at least one group with negative charge, and additionally at least one hydrogen atom with Zerewitinov activity.

Abstract: An electrically conductive lacquer adapted for use in heating elements is prepared by dispersing electrically conductive particles in an aqueous plastic dispersion in an aqueous silicate solution. Sodium or potassium silicate and an acrylic resin may be used in making the dispersion. The electrically conductive particles may be carbon or particles having a noble metal surface.
