| 摘要 |
The present invention is directed to a low-friction coating composition, comprising: about 10 to about 30 wt % of an epoxy resin composition consisting essentially of 4-glycidyloxy-N,N'-diglycidylaniline; about 30 to about 60 wt % of an epoxide resin composition consisting essentially of bisphenol A diglycidyl ether polymer; and about 20 to about 40 wt % of an aromatic amine composition consisting essentially of 4,4'-sulfonyldianiline; wherein all weight percents are based on the total weight of the low-friction coating composition, and wherein the low-friction coating composition is substantially free of chromate. The invention is also directed to a substrate coated with the above low-friction coating composition, and methods of coating a substrate with the low-friction coating composition.
