POWDER COMPOSITIONS FOR PRIMER COATINGS SUITABLE FOR PVDF-BASED TOP COATINGS

摘要

Powder compositions comprising 5-15 wt % of PYdF-compatible thermoplasticresin, 50-90 wt % of a thermosetting bindersystem, 0-35 wt % of pigments and 0-3 wt % of levelling agent are suitable forlater application of a pigmented PYdF-based topcoating. Preferred compositions are based on an epoxy system containing about8 wt % of PYdF or acrylic thermoplastic resin,5-25 wt % of pigments and 0.7-1 wt % of levelling agent.
