Factory dip-applied protective coating for application to plate fin andtube coils.2. Coil factory assembled and tested before coating application.3. Coating suitable for coils with maximum 30 fins per inch fin density.Bridging of product across coil fins is unacceptable.4. After application and proper curing, product shall endure bending ofcoil assembly in standard manufacturing process without cracking.5. Apply coating to coil before final factory assembly of equipment.Coating process that requires disassembly of equipment for removal ofcoil to be coated is not acceptable.B. Coating Material: Use one of the following materials:1. Epoxy Modified Phenolic. Straight phenolic materials are notacceptable.2. Epoxy or epoxy urethane.3. Polyelastomer: Complex chain linked polyelastomer material.PW/WBG/382059UNITARY AIR-CONDITIONINGAUGUST 15, 2012EQUIPMENT©COPYRIGHT 2012 CH2M HILL 23 81 00 - 7
