Polyester kaplama çoklukla polibazik asit ve poliolün (kısmen doymamış polibazik asit dahil) polikondenzasyon reaksiyonu ile oluşturulan ve elan sonra bir kaplama filmi tekvin etmek üzere mirlatıcı ve hızlandırıcının etkisi altında çapraz bağlanan ve kürlenen bir komonomer ile karıştırılan polyestere atıfta bulunur. Kaplamalara geleneksel olarak polyester kaplamalar denir.
