  • Patent number: 4812356
    Abstract: A one-component coating composition of35 to 60 wt.-% isocyanate prepolymer8 to 15 wt.-% plasticizer0.3 to 2 wt.-% antisettling agent2 to 10 wt.-% flaky extender5 to 25 wt.-% colorant pigments1 to 3 wt.-% moisture-binding agent, and10 to 20 wt.-% aliphatic estersprovides, on a flexible substrate such as artifical leather, plastic film, paper, roofing felt, polyurethane hard and soft foams, metal foils, concrete and the like, an extraordinarily elastic, tightly adherent coating film of high covering power and light resistance. Furthermore, it has good resistance to abrasion and to weathering, even to aggressive media such as sea water and chemicals.

  • Patent number: 4567230
    Abstract: A moisture-setting single-component coating composition has a content of 15 to 70 wt.-% of polyurethane-forming isocyanate, 5 to 25 wt.-% of light-colored, liquid, aromatic hydrocarbon resin of low molecular weight containing hydroxyl groups, 0.2 to 2 wt.-% of antisettling agent, 10 to 35 wt.-% of foliated filler, 2 to 25 wt.-% of tinting pigments, 1 to 5 wt.-% of moisture-binding agent, remainder, but no less than 5 wt.-% of conventional paint solvent. This coating composition can be applied in a conventional manner to a dirt- and dust-free substrate in a thickness of at least 20 microns, and sets of itself by the access of moisture from the ambient atmosphere. The coating composition is suitable especially for the protection of roofs of all kinds, for coating concrete, for protecting reinforced concrete against corrosion, for the painting of steel roofs and/or for the sealing of flat roofs covered with roofing felt.

  • Patent number: 4279962
    Abstract: To provide a cover coating for metal surfaces subject to corrosion by water, typically steel surfaces in salt water, for ships, structural components, and the like, in which cathodic protection by application of a negative voltage to the metal is provided, a two-layer coating is applied in which the base coating applied to the metal comprises a mixture of finely divided zinc and polyisocyanate prepolymers capable of hardening or curing under ambient humidity, with dryers, gelling, and pigment agents, and high boiling point solvents, covered by a cover coating, preferably in two to three layers, of a mixture of tar with polyisocyanates, fillers, dryers, solvents, and micaceous iron ore or hematite powder.
