Poor adhesion of electrostatic spraying on PET products
ظاهرة المشكلة
The adhesion of electrostatically sprayed coating on the surface of PET products is insufficient, and the coating peels off.
تحليل الأسباب
Poor PET surface conductivity causes uneven charge accumulation during electrostatic spraying, and coating powder adhesion is poor.
الحل
Apply a conductive primer to the product surface; appropriately increase baking temperature to bond the coating with the substrate; preheat the product.
الخلاصة الأساسية
PET electrostatic spraying requires conductive pretreatment to obtain good results.
