Results of investigating 01.09.03 №11[z]-25-04/791 about the chemical resistance of the coating “FOR THE SAKE OF [UNIPOL]”

In [TSKHL] are under laboratory conditions carried out studies of the chemical stability of coatings of paints “OF [UNIPOL]” before the aggressive media of joint stock company “Nevinnomyssk nitrogen”.

Before the process of experiment the represented paints of the enamel [SBE]-111 “OF [UNIPOL]” of stamps B and [VU] were brought down the metallic plates and were determined the indices of quality of coating (chemical stability and water absorption) in accordance with TU 2312-001-59846005-03 and ALL-UNION STATE STAN. 9.403-80.

After the end of tests is carried out the integrated assessment (visually) of the decorative and shielding properties of the investigated paints before correspondences ALL-UNION STATE STAN. 9.407-84.

The results of investigating the models are represented before Table 1-2.

Thus, coating on the basis of paints of the enamel [SBE]-111 “OF [UNIPOL]” of stamps B and [VU] is possible to use due to the conditions of joint stock company “Nevinnomyssk nitrogen” for the corrosion protection of equipment due to the atmospheric conditions and from the action of the aggressive media, where it is “steadfast”.
