PROBLEM TO BE SOLVED: To provide an organic impregnation solution forming a cured product compatibly having excellent oil-resistance and excellent coolant-resistance. SOLUTION: The impregnation solution comprises mixing the following substances: (A) 5-65 wt.% polypropylene glycol methacrylate; (B) 5-65 wt.% long-chain alkyl methacrylate having a kinematic viscosity of ≤20 cSt; (C) 10-40 wt.% low-molecular-weight methacrylate having a molecular-weight of ≤200; and (D) 0-10 wt.% polyfunctional methacrylate to introduce a crosslinked structure, while controlling the total weight of the mixed substances to 100 wt.%.
