What Does Moisture-Curing Coating Mean?
A moisture-curing coating is a type of coating that cures due to the presence of moisture in the atmosphere. This coating forms a protective coating film by reacting chemically with the moisture in the air. Moisture curing coatings are often applied on roofs, the outer surfaces of buildings and on marine equipment and vessels because they can cure in the moist air.
Corrosionpedia Explains Moisture-Curing Coating
Some advantages of moisture-curing coatings are that they offer resistance to ponding water, produce a highly reflective surface and possess good adhesion properties. Moisture-curing coatings also prevent pitting corrosion and bacterial corrosion on marine machinery.
The substrate surface needs to be pressure cleaned and free from oil, dust, dirt and other contaminants before a coating application.
Moisture-curing coatings are applied with by brush, medium nap roller or airless sprayer. The minimum pump pressure for the airless sprayer should be maintained at 2,500 to 3,000 psi with a spray nozzle having a tip size of approximately 0.035 inches.
