Results of investigating 01.09.05 №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, before [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 1-3. Table 1
