Poly ( conversion vinylidene) in base finished paint powder body constituent null for ideal undercoat paint

摘要

Powder compositions comprising 5-15 wt % of PVdF-compatible thermoplastic resin, 50-90 wt % of a thermosetting binder system, 0-35 wt % of pigments and 0-3 wt % of levelling agent are suitable for later application of a pigmented PVdF-based top coating. Preferred compositions are based on an epoxy system containing about 8 wt % of PVdF or acrylic thermoplastic resin, 5-25 wt % of pigments and 0.7-1 wt % of levelling agent.
