Elenco delle proprietà chiave e metodi di prova dei rivestimenti acrilici
Acrylic paint is acrylic acid and its copolymer as the main raw material, adding additives and solvents made of a kind of paint. Acrylic coatings have excellent weather resistance, resistenza alla corrosione chimica, strong adhesion and other characteristics, widely used in construction, automobile, shipping, mobilia, elettronica, machinery and other industries in metal, plastica, bicchiere, ceramics and other materials surface corrosion, decorazione, coating and other fields.

For each test, the specific steps will be different, and the corresponding test standards or methods need to be referred to. Some commonly used standards or methods include: ASTM, ISO, GB/T, eccetera. Attention should be paid to the accuracy and repeatability of the instrument, as well as the preparation and handling of the sample during the test.
