Patents Assigned to Companhia Nitro Quimica Brasileira
  • Patent number: 10934398
    Abstract: The present invention relates to an improved method for producing a colloidal nitrocellulose dispersion made compatible with a system of acrylic monomers polymerized with surfactants in a water-based system under pressure. The self-emulsifiable system of the present invention is characterized by the latex formed by the nitrocellulose suspension in an aqueous medium, with nanometric particles and homogeneity and, consequently, a greater covering and smoothing power, high adherence, high gloss, greater chemical and mechanical resistance, rapid drying, less water retention when used in paints, varnish and sealant compositions for coatings in the fields of graphic printing, such as flexography and rotogravure, lamination, nail polish, metal-mechanics, decoration, glass, leather, plastics, wood surfaces, compounds and mortars, decorative wall paints, textiles, paper coatings and car paint repairs, inter alia.
