The COT laboratory can perform a large number of analyses of paint and paint related products. It is equipped with various apparatus, as a FT-IR (Fourier Transformation Infra-Red) spectrophotometer to determine binders, an UV-VIS spectrophotometer to measure the titanium dioxide content, an AAS (Atomic Absorption Spectrophotometer) to determine pigments and extenders, a GC-MS (Gas Chromatograph – Mass Spectrophotometer) to determine among others solvents and PAH (Polycyclic Aromatic Hydrocarbons) and several smaller measuring apparatus.

Other variables which can be measured are the sand/cement ratio in concrete, amine number, epoxy number, acid number and hydroxyl number of binders/paints and volume solids according to ISO 3233 and ASTM D2697. We can perform emission measurements (e.g. formaldehyde) on paints and wood panels. Physical characteristics of paints, as density, viscosity, fineness of grind, pot life and drying, often determined in combination with chemical analyses, are presented in Physical properties.

Witnessing paint application

The required quality levels and specifications of coatings are increasing (for example in the oil and gas industry). In order to be able to meet the required specifications, the quality of the application becomes

Autoclave tests

Over the years, the demand for paint testing at high pressure and temperature in combination with corrosive gases increases. In various standards and specifications such as ISO 15741, EN 10289, EN 10290, ARAMCO 09-SAMSS-067 APCS 27,
