Patent ID: 8053488

Claim:
A surface treatment method using ambient temperature curable hydrophilic PU oligomer, comprising the steps of: providing a material comprised one of a textile and a glass, the material having a surface to be treated; forming an ambient temperature curable hydrohilc PU oligomer on the surface of the material; and curing the ambient temperature curable hydrohilc PU oligomer on the surface of the material, when the ambient temperature curable hydrohilc PU oligomer is an acrylate-terminated hydrophilic PU oligomer, and the curing process comprises the steps of: using UV-radiation irradiating the acrylate-terminated hydrophilic PU oligomer formed on the surface of the material, thereby obtaining an acrylate-terminated hydrophilic PU film on the surface of the material, wherein adding a reactive diluent into the acrylate-terminated hydrophilic PU oligomer before the acrylate-terminated hydrophilic PU oligomer being formed on the surface of the material, adding a photo-initiator or a photo-sensitizer with 5% by volume or below into the acrylate-terminated hydrophilic PU oligomer before the acrylate-terminated hydrophilic PU oligomer being formed on the surface of the material, and adding a coupling agent into the acrylate-terminated hydrophilic PU oligomer before the acrylate-terminated hydrophilic PU oligomer being formed on the surface of the material, and wherein the coupling agent is one of TEOS and VTES with 20 phr.
