Coatings Testing

Assess the quality of coatings under different environmental conditions

Assess the quality of coatings under different environmental conditions


Coatings are essential to protect surfaces, especially to those subjected heavily to wear and tear processes in any given environment. 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 main purposes of coatings are twofold, namely for its aesthetics and protection capabilities. Coatings can enhance the surface properties of the substrate in particular its appearance, adhesion, resistance to corrosion, wear, scratch etc. It can also protect the surface against external climatic conditions such as temperature, sunlight, radiation, humidity, rainfall, and even gaseous pollutants.

TÜV SÜD offers a comprehensive range of testing and evaluation services and our reports are accepted internationally.  TÜV SÜD has more than 40 years of experience in testing and laboratories are also accredited under the Singapore Laboratory Accreditation Scheme (SINGLAS).


TÜV SÜD testing services allow manufacturers, end-users and consumers to assess the durability and suitability of the coating materials applied on their products or systems. Our coatings laboratories offer a comprehensive range of testing and evaluation services covering organic and inorganic coatings such as paints, powder/fluorocarbon coatings, intumescent coatings, photocatalytic coatings, wood coatings, lacquers, polymeric materials, plated metallic coatings, etc.
