Coil Coating is a high-temperature solvent vapor monitoring application in which rolls of aluminum or steel are coated with a color finish, oven cured to desired specs and sold to makers of cans, rain gutters, home appliances, building & automotive products and other fabrications. Coil coating ovens typically operate at high temperatures, with some zones at over 800°F. This temperature range is needed to cure organic polymer coatings to their substrate materials.
Solvents are typically vaporized in the early oven zones. At the same time, however, other materials are also vaporized: resins, plasticizers, additives, and other compounds.
Examples of coil coating applications include:
- Metal Coating
- Steel Coating
- Sheet Finishing
Coil coating requires the use of a gas detection system, like the PrevEx Flammability Analyzers, to monitor the flammability of the solvent vapor driven off during the drying process. It should accurately measure solvent mixtures and withstand the temperatures required to prevent sample clogging aoiding re-caibratino and unnecessary downtime.
