Patent ID: 8877088

Claim:
A bi-component formulation comprising component A and component B, wherein: said bi-component formulation is a paint; the stoichiometric proportion of component B to component A is at least 3:1; the component A comprises: i. 4 to 15% by weight of a solvent selected from the group consisting of an ester, a ketone, an aromatic hydrocarbon, an acetate, and mixtures thereof, ii. 3 to 5% by weight of a rheological additive, which is a modified clay, iii. 0.4 to 0.6% by weight of a dispersing agent, wherein the dispersing agent is a mineral-oil derivative, iv. 0.3 to 0.6% by weight of an antifoaming or de-aerating agent selected from the group consisting of vinyl polymer, mineral oil, silicone and mixtures thereof, v. 0.4 to 0.6% by weight of a wetting agent selected from the group consisting of multifunctional silicone, mineral oil, sodium polyacrylate and mixtures thereof, vi. 5 to 10% by weight of a mineral filler selected from the group consisting of calcium carbonate, magnesium carbonate, magnesium silicate, and mixtures thereof, vii. 30 to 40% by weight of a film forming agent, which is a polyester derived from polyethylene therephthalate (PET), viii. 1 to 3% by weight of a plasticizer is selected from the group consisting of castor oil, chlorinated paraffin and mixtures thereof, ix. 10 to 15% by weight of a pigment paste having a fineness of 7 hegmans and comprising: 30 to 50% by weight of a pigment selected from the group consisting of mineral, metallic, organic pigments and mixtures thereof, 28 to 50% by weight of a solvent selected from the group consisting of an ester, a ketone, an aromatic hydrocarbon, an acetate, and mixtures thereof, 2 to 4% by weight of a dispersing agent, wherein the dispersing agent is a mineral-oil derivative, 0.4 to 0.7% by weight of an antifoaming or de-aerating agent selected from the group consisting of vinyl polymer, mineral oil, silicone and mixtures thereof, 15 to 25% by weight of a grinding carrier selected from the group consisting of short chain alquidic resin in plant oil and hydroxylated acrylic resin, x. 1 to 3% by weight of a first surface activity additive, which is hydroxyl alkyl pro-pyldimethylsyloxane resin which may be wholly or partly substituted with functional acrylic polydimethylsyloxane or modified polyether, xi. 2 to 4% by weight of a second surface activity additive, which is polytetrafluorethylene, xii. 1 to 2% by weight of an agent that enables self-cleaning, which is fluorochemical, and xiii. 2 to 4% by weight of an anti-incrustation, antifungal and moss/slime/algae-formation inhibiting agent is a mixture of plant extracts, isothiazoline, mineral oils, cationic surfactants and glycol; and the component B is selected from the group consisting of 2,4 toluene isocyanate, 2,6 toluene diisocyanate and mixtures thereof.
