“…The fine-crystalline structure of the phosphate protective membrane contributes to the good absorbency of paint and thus improves their adhesion. The inert matrix of inorganic phosphates can be modified with various active additives [1,2]. Thus, water-based rust converter NOTECH derived on phosphoric acid and acidic zinc phosphates with the addition of water-soluble inorganic inhibitors-oxidizers of the anode type is known and used in practice [3].…”

A combined approach to paint was used to increase the effectiveness of anti-corrosion protection was used. In particular, passive insulating coating materials was modified with active additives. A water-soluble anodic inhibitor of atmospheric corrosion was encapsulated in a phosphate conversion coating NOTECH. As a result, the corrosion under a layer of paint primer was suppressed. It is important that phosphating does not create a layer like paint. So, such an approach is universal and compatible with most known types of paint coatings and can be combined with temporary protection (preservation). The second paint layer of the coating contained a water-oil-soluble corrosion inhibitor of the group “M”, namely: N-M-1. It is adduct of natural fat vegetable acids and cyclohexylamine. The data of corrosion tests and polarization curves are presented, which confirm the high protective properties of the proposed binary inhibitory anti-rust paint.

The aim of this study was to assess the possibility of using wastes from pulp and paper industry as metal corrosion inhibitors. We studied protective properties of various systems, including the primers with rust modifiers developed on the basis of sulfite spent liquors and an upper coating layer of PF-115 enamel applied to a rusty surface. Using the gravimetric method and the method of polarization curves, we found that sulfite spent liquors inhibit steel corrosion in an acidic environment. We found that the P-2 rust modifier with an addition of lye + piperidine is the most effective inhibitor of steel rusting.
