THERMOSETTING POWDER COMPOSITIONS FOR PRIMER COATINGS SUITABLE FOR PVdF-BASED TOP COATINGS

摘要

powder compositions containing 5 to 15% by weight of a thermosetting resin binder system is compatible with the pvdf, 50 to 90% by weight of a thermosetting resin binder system is incompatible with the pvdf, 0 to 35% by weight of pigment and 0 to 3% by weight of the product. ivelant are suitable for the subsequent application of a finishing layer of pigmented pvdf.preferred compositions are based on a system of about 8% by weight of an epoxy resin and a fluorinated acrylic, 5 to 25% by weight of pigment and 0.7 and 1% by weight of product grading.
