  • Organism adhesion reduction paint, method for manufacturing the same, and organism adhesion reduction coating
    Patent number: 10759910
    Abstract: A method for manufacturing an organism adhesion reduction paint includes a first process of gelling a raw material composition that includes polyvinyl alcohol and at least one of a hydroxyl group-containing inorganic compound or an inorganic oxide; a second process of drying and subsequently pulverizing a resulting product in the first process to thereby obtain a composite gel fine powder; and a third process of adding the composite gel fine powder to a main component of a two-component urethane paint and stirring, to thereby prepare a main component of the organism adhesion reduction paint, and also adding a curing agent immediately before use.
