Surface coating methods

Common Surface Coating Curing Methods

• Room temperature curing: Often used for RTV electroplastic coatings or RTV elastomeric coatings, room temperature curing involves allowing a coating to cure in ambient conditions with proper ventilation. The moisture in the air aids the curing process when relative humidity levels are optimal.
• Mild heat acceleration: This curing method is similar to room temperature curing, as the coating cures in ambient conditions for a specific period. Afterward, workers expose the coated surface to warmer conditions, per the coating manufacturer’s recommendations. This method is not appropriate for solvent-less heat cure coatings.
• Heat curing: Best for solvent-less heat cure coatings as they don’t require moisture to cure, this type of curing exposes a coated surface to temperatures above 100°C in an oven.
• UV curing: A process that uses ultraviolet lights to induce a photochemical reaction that quickly cures a surface coating without the use of solvents. A polymerization reaction, rather than evaporation, cures the coating.

In regards to curing for tank surface coating applications, it is important to keep in mind that curing processes often require specific air temperatures, surfaces temperatures and relative humidity levels to dry and cure properly. Conditions that are too cold or too humid, for instance, tend to increase drying and curing times. Conversely, hot, arid conditions speed up drying times, but might not allow a coating to cure properly.

Contractors often encounter curing-related problems when they rely on the weather to cooperate rather than use Polygon’s temporary climate control solutions. The custom-designed solutions allow you create the optimal environmental conditions needed to maintain a tank’s ideal surface temperature and promote predictable curing times. Proactive contractors that use climate control systems ultimately save money, stay on-schedule, keep workers more productive, prevent costly delays and improve customer service. More importantly, use of the equipment helps prolong a protective coating’s duration because it cured properly during the application process.
