Definition - What does Breathing-Type Coating mean?
Breathing-type coating is a coating material that is fully permeable to allow the transition of vapour through it without being negactively impacted. It is a particularly useful type of coating in material systems such as concrete that require regslated moisture levels but a fixed amount of protection from the external environmental elements.
Corrosionpedia explains Breathing-Type Coating
Breathing-type coating is primarily designed for use over insulation material to aid in the maintenance of its efficiency. It is typically designed to give a low rate of moisture transmission for insulation operating at high temperatures and vice versa.
