| Abstract: | A epoxy coating was prepared and coated on polyimide film and then cured to prepare coating polyimide film.A modified epoxy adhesive was coated on the other side of coating polyimide film and covered with release paper to prepare a chemical resistance coating coverlay.A comparison test was taken between normal coverlay and chemical resistance coating coverlay.The results showed that the chemical resistance coating could protect polyimide film from being corroded by alkali liquor and desmear potion.Chemical resistance coating coverlay and normal coverlay were roughly equivalent in terms of flexibility,heat aging resistance,heat resistance,mechanical properties,folding resistance and laser processability. |
