Coatings are essential to protect surface of the substrate subjected heavily to wear, scratch and corrosion processes in any given environment. It can also protect the surface against external climatic conditions such as temperature, sunlight, radiation, humidity, rainfall, and even gaseous pollutants. Coatings can enhance the surface properties of the substrate in particular its appearance and adhesion. The quality of coatings are important considerations when producing products with high performance and avoiding product failures. It is important to test and assess their performance in different environments.
The chemical composition and physical properties of coatings have a direct impact on their performance. Accordingly, it is essential to conduct comprehensive coating testing and analysis programs. STEMart provides a comprehensive range of testing and evaluation services to allow manufacturers, end-users and consumers to assess the durability and suitability of the coating materials applied on their products or systems.
