The US Army Corps of Engineers (USACE), Walla Walla District, is seeking a brand name justification and approval for specific ingredients in the vinyl paint formula used for the McNary Powerhouse Turbine Draft Tube Slot Filler project. This is due to the unique properties of these ingredients, which have been extensively tested and approved by USACE Construction Engineering Research Laboratory (CERL) for protective coating on underwater steel structures. The identified brand-name ingredients from Kronos, Inc., E.I. Dupont DeNemours and Co., Inc., Elementis Specialties, Wacker Chemie AG, Momentive Performance Materials Inc., and Dow Corning Corporation are crucial for the paint's performance and longevity, with alternatives potentially leading to inferior coatings, increased maintenance costs, and delays. Despite the brand-name requirement for specific ingredients, multiple manufacturers can supply the complete vinyl paint system, allowing for competitive pricing for the overall system. The estimated cost for the specific brand-name ingredients is $6,600.
