Kind Code:

A1

Abstract:

[Problem] To provide a surface protection material which exhibits excellent UV resistance and is capable of protecting the surface of a prepreg that serves as a base material, while being capable of preventing deterioration of a fiber composite material due to UV and defects during coating, and which enables the control of resin flow, while being suppressed in the volatilization amount during the curing. [Solution] A coating agent for spraying or hand coating, said coating agent being composed of an epoxy resin composition that contains at least constituent elements (A) to (D), wherein from 90 to 100 parts by mass of the constituent element (A), from 15 to 75 parts by mass of the constituent element (B), from 0.05 to 75 parts by mass of the constituent element (C) and from 0.1 to 10 parts by mass of the constituent element (D) are contained relative to 100 parts by mass of the whole epoxy resin. (A) a non-aromatic epoxy resin (B) a pigment having an average particle diameter of from 0.1 to 10 μm (C) a non-aromatic thermoplastic resin (D) a cationic curing agent or an anionic curing agent
