Coating mass is the amount of coating applied to the surface of a base material, typically expressed in grams per square metre (g/m²). For differential coatings, the coating mass on each surface is determined separately.
A common method for determining coating mass involves weighing the coated test specimen, chemically stripping the coating without significant attack on the base material, then cleaning, drying and reweighing the specimen. The difference in mass is used to determine the coating mass per unit area.
LMATS provides coating mass testing for metallic and other coatings in accordance with applicable Australian and international standards and client specifications.
Testing can be performed to requirements including:
