The problems of corrosion control came into being a thousand years ago. Annually the market introduces new anticorrosion materials and recently – the systems of anticorrosive protection.
We put forward the systems of anticorrosive protection based on epoxy resins aqueous dispersions:
– for thick-film coating (heavy coatings) that subject to simultaneous effects of the aggressive media, mechanical impact and abrasion it is a system based on the ground coat WD EPEP -72 and PTSR E-30.
The coatings based on the system «ground coat – paint» are elastic and frost resistant. The system is recommended in the quality of anticorrosive and chemically resistant coatings on metal and reinforced concrete surfaces. In relation to its performance characteristics the system is equal to epoxy paints based on organic solvent -borne resins and is more immune to alkalies than the latter. Due to the lack of the organic solvents the system makes possible to be operated in a closed space.
