The proposed rust converter, elaborated by two Bulgarian research organizations is a multi-component mixture in a liquid phase, the latter containing some organic and inorganic compounds and a small amount of water. The active rust converting agents are inorganic salts with adsorption-oxidizing activity and complex agents. The presence of selected organic compounds greatly increases the wettability of the rusted surface which allows the penetration of the converter into the finest pores and micro-cracks of the rusty mass thus ensuring complete interaction with it, as well as complete rust-conversion process and excellent adhesion to the metal, respectively.
For a short period of time (several hours), the rust existing on the surface of the ferrous metals and alloys is transformed (converted) in the form of higher oxides and phosphates of iron, the latter being insoluble and resistant covering the surface with a dark protective film with high adhesion properties.
The resulting protective surface film can perform two basic functions - barrier-shielding against the corrosion aggressiveness and being in fact a reliable primer for sequential deposition of different polymeric or other decorative and protective coatings.
The composition could be imposed as a relatively new generation in the group of converters and complies with the requirements for better corrosion resistance and protective ability.
It can be used in the energetic, engineering, metallurgy, chemical and ore mining, for different constructions in the civil engineering, in the transport industry, agriculture, army and others.
The team members offer technical co-operation to engineering and manufacturing companies interested in the rust converter production and commercialization. The proposed collaboration type is commercial agreement with technical assistance.
