| 摘要 |
A two-component coating system comprises (A) a polyfunctional acid (dimer acid), low base strength amine (aniline), and high base strength amine (cyclohexylamine) adduct of a diglycidyl ether of bisphenol and (B) an organic diol reacted with 2 moles of a diisocyanate. The coating is particularly adapted for coating surfaces subject to high abrasion, e.g., railroad hopper cars. |
