What Does Weatherability Mean?

Weatherability is the ability of a material or structure to withstand, resist or endure harsh atmospheric weather conditions, such as extremely hot or cold temperatures, humidity, salt air or similar corrosive conditions. Weathering tests are conducted to understand the effects of weather on any structure and help determine the weathering characteristics of materials and coatings.


Corrosionpedia Explains Weatherability

Coatings and paints that are intended to provide a barrier between a substrate material and the outside weather is first tested for its weatherability. An appropriate coating is selected based on the results of how the coating reacted to tests simulating the weather conditions where the coated materials will be used.

Some simulated weather conditions include moisture, humidity, UV radiation, temperature, salinity and acidic environmental conditions. Scientists and testers look for any changes in wear resistance, gloss or pigmentation.
