Liquid crosslinking agent and coating fluid of liquid crosslinking agent

Abstract

Provided is a liquid crosslinking agent in which liquid life (pot life) as an undiluted solution is sufficiently long and excellent coating properties are exhibited when used. A liquid crosslinking agent containing an epoxy compound and an emulsifier, in which a content of water is 39% by mass or less with respect to a total amount of a liquid, and a contact angle with respect to a poly(ethylene-methacrylic acid) film when preparing an aqueous dispersion in which a concentration of a non-volatile component is 15% by mass is 42.0° or less. It is preferable that the epoxy compound has two or more epoxy groups in molecules, and it is preferable that the emulsifier is a nonionic surfactant. Provided is a coating method of a liquid crosslinking agent including diluting the liquid crosslinking agent with water to be used for coating.
