LORENIZEDTM BENEFITSLORENIZED is an electrostatically applied, baked polyester powdercoating. This coating technology offers good chemical resistance, excellentmechanical performance and excellent protection from outdoor elements.SUPERIOR QUALITIESSUPERIOR QUALITIESDURABLE PROTECTION, LASTING BEAUTYENVIRONMENTALLY FRIENDLY COATING PROCESS All steel fan and blower components receive Cook’s Lorenized coating as thefactory standard. When this coating goes on, it stays on. The entire procedure occurs within a self-contained, automated system. Waterused in the pretreatment recirculates and is neutralized before its release fromthe system. Excess powder is captured and recycled. It’s the industry’s most durable standard coating. It comes out sleek and smooth,and it stays that way. Cook’s Lorenized coating withstands the elements andprovides durable protection and lasting beauty. No solvents are utilized so there are no polluting fumes or paint vapors to escape.There is virtually nothing in the entire process to adversely affect our environment.FIVE STAGE PRETREATMENT12140 FALKALINE CLEANER345250 F140 FFRESH WATER RINSEIRON PHOSPHATECOATINGFRESH WATER RINSEAMBIENT CHROMEFREE SEALERDRYING OVEN400 FELECTROSTATICALLYAPPLIED POWDERCURING OVEN Steel components go through a five stage pretreatment process before the powder is applied. They are washed and treated until all surfaces are perfectly clean,chemically prepared and electrostatically charged–ready to bond with the powder.This ensures excellent coating adhesion, uniformity and consistent edge coverage. Then, a worker or an automated system of sprayers applies the powder that chemically bonds to the prepared surface. Components are then cured in a 400 F oven.This process creates adhesion, durability and a smoothness of coating not possiblewith conventional liquid paints.3
