The present invention provides a curable composition having an excellent permeability to a porous substrate and a sufficient strength for use as a coating film, and also having a suitable curing time (set time), accordingly the curable composition having a pot life from the application until the completion of the permeation to pore portions. Particularly, the present invention also provides a favorable coating agent for surface reinforcement coating of a porous substrate. These objects can be achieved by using a curable composition containing the following (A) and (B): (A) a cyanoacrylate compound; and (B) a hydrofluoroether having such a structure that the number of carbon atoms substituted only with fluorine in the molecule is 1 or more to 6 or less, and the number of carbon atoms in the molecule is less than 7.

Disclosed is a two-part composition for sealing natural stone or masonry, and methods of use. The two-part composition is comprised of (1) a first part comprising a polyvinylidene fluoride (PVDF) particulate; a low evaporation rate organic solvent; and water; and (2) a second part comprising a blend of a plurality of liquid resin formulations.

Disclosed is a moderator for moderating neutrons, including a substrate and a surface treatment layer or a dry inert gas layer or a vacuum layer coated on the surface of the substrate, wherein the substrate is prepared from a moderating material by a powder sintering device through a powder sintering process from powders or by compacting powders into a block, and the moderating material includes 40% to 100% by weight of aluminum fluoride; wherein the surface treatment layer is a hydrophobic material; and the surface treatment layer or the dry inert gas layer or the vacuum layer is used for isolating the substrate from the water in the environment in which the substrate is placed. The surface treated moderator can avoid the hygroscopic or deliquescence of the moderating material during use, improve the quality of the neutron source and prolong the service life.

A method for producing a building material includes a first step of applying an undercoat paint onto a surface of an inorganic base material, curing the undercoat paint, and polishing the undercoat paint; and a second step of applying an enamel paint onto the undercoat paint and curing the enamel paint. The undercoat paint contains an undercoat-forming material and a filler. The enamel paint contains an enamel-forming material and a pigment. The enamel-forming material is a solvent-based resin. A content of the filler in the undercoat paint is 40% to 70% by mass in terms of solid content. A content of the pigment in the enamel paint is 1% to 50% by mass in terms of solid content.
