PROCESS FOR PREPARING A STABLE AQUEOUS DISPERSION OF POLYAMIDE-IMIDE WHICH IS FREE OF CARCINOGENIC, MUTAGENIC OR REPROTOXIC SUBSTANCES, AND APPLICATION TO COATINGS |
| 摘要 |
The invention concerns a process for preparing an aqueous polyamide-imide dispersion, characterized in that it comprises at least one step of selecting a polyamide-imide powder and a step of producing a dispersion comprising the polyamide-imide powder, a polar aprotic solvent with a boiling point of more than 180° C. at 760 mm Hg, and water. The invention also concerns a process for producing a dry polyamide-imide film on a substrate. |
