thenex® stands for utmost safety and quality. It is of vital importance for the safety of refinery and petrochemical process vessels and transfer lines to avoid excessive heat.
Therefore, thenex provides temperature indicating paints which change their colour when a certain temperature is obtained. This colour is clearly visible and a damaged area can be located in an easy manner: And therefore TI-paints are perfect early warning indicators of overheating.
Properties of the cured film
In addition to the good corrosion and weather resistance, the color is resistant against e.g. oil, grease, gasoline, mechanical resistance and particularly high heat.
The TI Paints are preliminary used in order to ensure the safety of refinery and petrochemical process vessels and transfer lines to avoid excessive heat. Overheating usually occurs due to damage on the inside of the equipment (e.g. by failure of the refractory lining), which cannot be controlled.
The paint is processed on surfaces where high heat resistance is required.
The paint indicates insulation defects and irregular heat transfer due to manufacturing defects in the process.
On which surfaces?
The paint is suited for treatment of steel surfaces.
How should the surface be prepared?
The surface should be shot-blasted. General recommendations acc. EN ISO 12944 part 4; grade of shot-blasting SA3 / ISO 8501-1 roughness number Rz 25-40μm. The surface should also be free from pollutions.
The picture shows the colour gradients of different paints at different temperatures.
