Primer Compositions for Non-Stick Coatings and Method for Manufacturing Same |
| 摘要 |
Provided is a primer composition for a non-stick coating which includes a polyamide-amic acid having an acid value of 50 to 200 mg KOH/g, a Lewis base, water and at least 5 wt % of a polar aprotic solvent relative to the total weight of said composition. According to the invention, the weight ratio of PAI/polar aprotic solvent in said composition is at least 1.5. Also provided is a method for preparing such a composition, and a method for manufacturing an item comprising a metal substrate to which such a composition is applied. |
