Latest Patents
Elisabet Johansson holds a patent for a soil-repellent coating composition. This composition comprises silica, polyvinyl alcohol, and a wetting agent in an aqueous carrier medium. The formulation is characterized by containing 0.5-30% by weight of silica, 0.01-6% by weight of polyvinyl alcohol, and 0.05-2.5% by weight of a wetting agent. The ready-made coating composition includes 0.05-5% by weight of silica, 0.05-0.5% by weight of polyvinyl alcohol, and 0.05-0.5% by weight of the wetting agent. The silica is present in the form of an alkali stabilized silica sol with an average particle size of 4-30 nm. The polyvinyl alcohol has a hydrolysis degree of 85-100% and an average molecular weight of 15,000-100,000. The weight ratio of silica to polyvinyl alcohol is above 3:1, preferably from 5:1 to 40:1, and the wetting agent is nonionic. The aqueous carrier medium may also include a water-miscible, low-boiling solvent such as ethanol in an amount of up to 20% by weight.
