The effects of flamespray coating conditions on two ethyleneβcarboxylic acid copolymers (Primacor 1420 and Nucrel 535) and a polyether block amide (Pebax 5533) on crystallinity and mechanical properties were investigated by differential scanning calorimetry (DSC), Gardner impact resistance, and conical mandrel bend tests. Plastic flamespray provides a means to apply thermoplastic powder coatings in the field with a wide range of properties to meet specific application requirements. The flamespray process did not significantly affect the crystallinity in the polymers studied, however, polymers possessing functional groups in the backbone such as the polyether block amide may experience some reduction in physical properties during the flamespray coating process. We have also successfully applied some high temperature thermoplastics (such as liquid crystal polymers) providing for coatings, with outstanding temperature and chemical resistance.
