Abstract
An anti-corrosive material includes an ultraviolet curable resin including, as a main component, a polymerizable compound including at least one of a photopolymerizable (meth)acrylate monomer or a photopolymerizable (meth)acrylate oligomer, and an anti-rust agent. The polymerizable compound includes a combination of a monofunctional (meth)acrylate monomer and a bifunctional (meth)acrylate monomer, or a combination of at least one of a monofunctional (meth)acrylate monomer or a bifunctional (meth)acrylate monomer and at least one of a trifunctional (meth)acrylate monomer or a polyfunctional (meth)acrylate monomer having four or more functional groups. The anti-corrosive material has a viscosity of 18,900 mPa·s or less.
Claims4
An anti-corrosive material, comprising:
