Research Overview

Corrosion of materials and protection against it is one of the oldest directions of work in the Institute of Inorganic Chemistry (since 1946). In the Laboratory of Protective Coatings wide investigations have been performed in this direction concerning the phase and chemical composition of corrosion products of steel, low-alloyed steels, aluminium alloys as well as activity and stability of corrosion products in various media. The obtained results had stimulated the elaboration of the so-called “rest modificators” with a task to inactivate and stabilize the corrosion products so allowing the painting of goods and constructions

without the perfect previous cleaning of their surfaces.

The items elicited:

- the formation and features of composition of corrosion products in the relatively unpolluted (country-side, maritime) atmosphere as well as in that various industrial enterprises;

- the significance and action mechanism of the alloying additions (copper, manganese, nickel, chromium) responsible for the enhanced atmospheric stability of low-alloyed steels;<

- the criteria of scientifically motivated choice of low-alloyed steel produced in the eastern European countries for the engineering constructions based on the exploitation conditions of the batter.

Products:

- the prescriptions of rust modificator for the slightly and moderately chemically aggressive media;

- the technological regulations for preparation of rust modificators;

- the instructions of application of rust modificators;

- the technological recommendations for protection of metallic constructions in cattle-sheds;

- the technology for protection of metallic constructions in hothouses.

-         anticorrosion compositions and technologies for clean-up the windows (in metallic frames) in hothouses and plants.

-         elaboration of functional additives for quality for improvement of alkyd paints and acryl dispertions.

The Laboratory of Protection Coatings has more than 40 year’s skill in protection of natural stone materials (carbonate rocks, sandstones) and various building materials against the atmospheric corrosion utilizing mainly methylsilanetriol complexes (MSTC) with various metal ions and organic molecules in water solutions.

We have manufactured:

-hydrophobic long-life facade paint;

- water-soluble paint for wooden houses;

- hydrophobizators for wood surfaces;

- non-fading pigments for surfaces;

- hydrophobizators for clothes from natural fiber;

- preparation for boreholes (for use at temperatures above 200 C) - in oil production;

- inhibitor of scaling corrosion of aluminium alloys. 

Services

in the field of restoration:

- atmosphere pollution-proof binder for copper artificial patina;

- protectors and stabilizers of natural patina for disintegrating stone monuments;

- preparations against the moss growth;

- artificial limestone - a substituent of Allazi calcareous tufa;

in the field of veterinary:

- preparation FAMS for treatment of tympanities (introduced into practice).

On the basis of MSTC studies in other organizations have been carried out to elaborate:

- ion-exchange threads for binding of heavy metals and decreasing of cloth wear.

Investigations of the methylsilanetriol complexes have been continued concerning their structure, surface activity and application in national economy. A procedure has been elaborated for separation of alkali metals from MSTC by chemical means.

We wish to collaborate with partners being interested in application of methylsilanetriol complexes in medicine and cosmetics as adsorbents for several substances as selective gas-permeable membranes, for separation of SO₂ etc.
