5. Schneider Electric 5 - Division - Nom – Date Why use epoxy-polyester hybrid powder coating ? epoxy is an excellent coating to control corrosion. ●Epoxy-based paints can adhere very well to a metallic surface if that surface is prepared correctly. Because of its bond to a metallic substrate and the internal bonds in the paint itself, epoxy is an excellent coating to control corrosion. ●However, epoxy paint systems have a major problem dealing with ultraviolet light - the material decomposes, causing what is known as chalking. ●Polyester paints, gives durability of appearance and mechanical strength to provide an excellent coating. ●SCHNEIDER Universal Enclosures uses a hybrid powder coating to provide the best quality.

11. Schneider Electric 11 - Division - Nom – Date Powder painting : The powder painting is done in low pressure cabins compare to the ambient atmospheres. The powder is charged at a reverse polarity from the one of the items being painted, powder then adheres on the items. All the part are also manually painted wherever exists a risk of insufficient coating( principally in the corners). =S= UE painting process (3) Powder painting process
