WATERPROOFING METHOD FOR HYDROPHILIC SURFACE AND WATERPROOFING SOLUTION FOR HYDROPHILIC SURFACE

摘要

A waterproofing method for a hydrophilic surface and a waterproofing solution for a hydrophilic surface, of the present invention, allow application of a method for pressurizing a surface treatment sheet having a waterproofing solution impregnated therein so as to waterproof the surface of a hydrophilic substrate, such as paper coated with PVA, while minimizing damage to the substrate or generation of toxic gas, thereby enabling a waterproofed substrate to be efficiently provided in an eco-friendly manner.
