Provided is a water repellent coating film, including: an undercoat layer formed on a surface of a base material and containing: at least one type of spherical particles having an average particle diameter of 2 μm or more and 50 μm or less and selected from the group consisting of spherical molten silica particles, spherical molten alumina particles, and spherical silicone resin particles; and an underlying resin; and a topcoat layer formed on the undercoat layer and containing: inorganic fine particles having an average particle diameter of 2 nm or more and 20 nm or less; and a water repellent resin. The underlying resin is preferably a polyurethane resin or a fluororesin. The water repellent resin is preferably a fluororesin or a silicone resin.

A construction material includes a base material. The base material includes a low-gloss region having a 60° gloss value of smaller than and a high-gloss region having a 60° gloss value of larger than or equal to 8. The 60° gloss value of the low-gloss region and the 60° gloss value of the high-gloss region are different from each other by 5 or greater.

The present invention relates to an aqueous flame-retardant coating composition comprising an inorganic phosphate, inorganic particles, an aqueous binder resin soluble or dispersible in water, and water, wherein the content of the aqueous binder resin is from 3 to 60 parts by mass based on 100 parts by mass of the total of the inorganic phosphate and the inorganic particles.

This electrical steel sheet includes a base steel sheet, a first insulation coating formed on a first surface of the base steel sheet and having adhesiveness, and a second insulation coating formed on a second surface of the base steel sheet which is a back surface to the first surface and having adhesiveness, in which an average pencil hardness of the first insulation coating is HB or higher and 3H or lower, and an average pencil hardness of the second insulation coating is higher than the average pencil hardness of the first insulation coating.

A solvent composition includes an organic solvent including one or more organic solvents (A) and one or more organic solvents (B), and one or more types of core-shell polymer particles each comprising a core layer and a shell layer. The organic sol vents (A) have a polar teen δp of a Hansen solubility parameter of less than 11 and a hydrogen bond term δh of less than 10, and the organic solvents (B) satisfy at least one of 11 or more of the polar term δp or 10 or more of the hydrogen bond term δh. A weight ratio of (A) to (B) ranges from 15:85 to 95:5.
