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.

Schneider Electric 6 - Division - Nom – Date Paint ： Advantage of hybrid paint  Resistance to shock,  Easy to clean,  Excellent corrosion and chemical resistance,  Good edge angle coverage  Good process efficiencies with excellent control over film thickness.

Schneider Electric 8 - Division - Nom – Date Overview Wash, Rinsing Phosphate Coating Line Powder Painting Baking ●We offer a number of standard colours including RAL 7035 and RAL The ultra durable powder paint is applied to a multi-staged washing, rinsing and phosphating undercoating. ●Our standard finishes can be re-painted.

Schneider Electric 9 - Division - Nom – Date Alkaline degreasing ： take away all the greases and impurities 120sec./ 60 ℃ Rinsing out ： triple spray 120 sec. =S= UE painting process (1) surface treatment tunnel Phosphate treatment ： allows better paint adhesion and higher resistance to corrosion 120sec./ 50 ℃ Rinsing out ： take away the exceed of phosphate by triple splay 120sec. Chromate neutralization ： mix of steel + chromate, offer a greater resistance to corrosion 45sec. Final rinsing out ： with mineral free water

Schneider Electric 10 - Division - Nom – Date Drying oven : 24m long oven, heated with town gas, ensure a perfect dryness of the parts =S= UE painting process (2) Drying oven

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
