arcospray 38®, 38 mN/m, colourless, spray, 100 ml, spray bottle

The arcospray 38® test ink is a test liquid with 38 mN/m surface tension. It was developed to quickly determine whether the surface is grease-free,It was developed to quickly determine whether the surface is grease-free, as it can be assumed that it is grease-free from this value. arcospray 38® can be cleaned off without leaving any residue after application using heat radiation - infrared. Tested parts can continue to be used. Not only large surfaces, but also very small surfaces, such as chain links, can be assessed quickly and easily using arcospray 38®. The determination of the surface tension is carried out by spraying the test ink onto the surfaces to be assessed. Application: - Hold the spray bottle at a distance of approx. at a distance of approx. 15 cm - Spray 2 to 4 times Result: If the test ink contracts, the surface tension of the test surface is lower than 38 mN/m. If the ink spray application remains remains unchanged, the surface tension value surface tension has reached 38 mN/mor slightly higher.
