  • Compositions for the production of opaque coatings by radiation
    Patent number: 4118366
    Abstract: Opaque coatings or films having a high covering capacity produced from coating compositions containing synthetic resins, fillers, solvents, common catalysts, sensitizers, additives and auxiliary agents, characterized in that radiation permeable mixtures of coating compositions are used containing the following components:A. 14 - 20 parts by weight, preferably 15 - 18 parts by weight, photosensitized light curing condensation resins having double bond values of 0.180 to 0.450;B. 55 - 75 parts by weight, preferably 65 - 70 parts by weight, or fillers having a low covering capacity;C. 0.5 - 10 parts by weight, preferably 1 - 6 parts by weight, of film forming cellulose derivatives or mixed polymerizates of vinyl chloride with other monomers which are compatible with A and B, andD.
    Type: Grant
    Filed: June 7, 1976
    Date of Patent: October 3, 1978

  • Cured opaque coating with high hiding power produced from normally transparent polyester paste filler compositions
    Patent number: 3993798
    Abstract: Cured, opaque coatings with high hiding power are produced on a substrate from a normally transparent and radiation transmitting unsaturated polyester paste filler composition containing customary additives, curing catalysts and optionally fillers of low hiding power and non-reactive solvents and/or plasticizers wherein the filler composition has a weight ratio of unsaturated polyester to the sum of copolymerizable monomers and optionally non-reactive solvents and plasticizers of from about 10 : 12 to 10 : 40, preferably from about 10 to 15. The unsaturated polyester filler composition may further have up to 95 percent by weight of the copolymerizable monomers replaced by the non-reactive solvents and/or plasticizers. The composition may be cured by UV rays, sunlight or other ionizing radiation.

  • Opaque polyester copolymer coated articles
    Patent number: 3933875
    Abstract: Opaque coatings and molded articles are produced from normally transparent copolymer compositions of unsaturated polyesters and monomers therefore by using from about 3 percent to less than 45 percent by weight of unsaturated polyesters based on the total weight of the composition.
