MAT-FINISH COMPOSITIONS FOR COATING SUBSTRATES

摘要

Mat-finish compositions for coating substrates, comprising thermoplastic or thermosetting resins such as polyamide, polypropylene, polyesters, epoxy resins and containing one or more matting agents maily in the form of needles or pellets having an average length of 1-200 mu m and an aspect ratio of 10-40. Said compositions, which are generally in the form of powders, are suitable for coating various substrates. The coatings are deposited, in particular, by fluid bed dipping and by electrostatic projection. The coated pieces can be furnishing, decorative or construction elements.
