Glass enamel for steel based on diatomite material

The possibility of replacing quartz sand for melting enamel frit by natural diatomite rock is investigated. It is established that the use of local diatomite as the silica material in melting enamel frits is a promising trend in enameling technology. The properties of frits based on diatomite materials are similar to the properties of the reference low-melting frit F-1; they have have slightly lower softening and melting temperatures, and their technological characteristics are within the limits specified by GOST 24495-80 for undercoat enamel on steel. __________ Translated from Steklo i Keramika, No. 5, pp. 36–37, May, 2006.

A Comparative Study of Anticorrosion Paints Based on Silicone-Urethane Binders: a Multilayer Primer

Using zinc phosphate, micaceous iron oxide and their combination in the composition of the undercoat, a series of novel multilayer paint systems based on different silicone-urethane binders with the same R/Si and Ph/R ratio have been formulated. The developed paint systems showed excellent mechanical, adhesion and chemical properties. Scanning Electron Microscopy (SEM) analysis of the surface of the paint systems shows no fractures or holes. The electrochemical impedance spectroscopy (EIS) evaluation of the developed paint systems confirms their excellent protective and anticorrosion properties, especially for Silicone-Urethane-Urea (SPUU) based paint systems with a combination of pigments in the composition of the undercoat. SPUU-based paint systems show low water uptake. The new multilayer silicone-urethane-based paint systems can be used as a anticorrosion primer.     

Process of formation of a high-quality enamel coating

The force action on the slip layer in the course of formation of an enamel coating on an article performing a complex motion is studied. The forces acting on ann elementary volume of the enamel slip are calculated. The main types of forces fostering removal of excess slip and formation of a uniform coating are identified. The conditions for producing a high-quality enamel layer are considered. Translated from Steklo i Keramika, No. 4, pp. 32 – 34, April, 2000.     

Development of heat-resistant anticorrosion urethane siloxane paints

Three two-layer heat-resistant and anticorrosion paints have been formulated from urethane siloxane binder and traditional anticorrosion pigments such as micaceous iron oxide (MIO), zinc phosphate (ZP), and aluminum oxide. These pigments were used as the dominant components of different undercoats or topcoats. Heat-resistant pigments such as silicon nitride and glass-spheres were used in the composition of the topcoats. Thermogravimetric analysis of paints shows that the paint with ZP as dominant component of the undercoat have the highest heat-resistance and stability in inert gas and oxygen. The paint with a combination of MIO and ZP has the best hardness as well as the best protective and anticorrosion properties based on the electrochemical impedance spectroscopy. A maximum synergic effect of the properties of pigments seems to appear in this paint. Surface morphology of paints was studied by means of scanning electron microscopy. Heated at different temperatures and for several hours, paint containing MIO as the dominant component in the undercoat exhibits the best mechanical and adhesion properties.     

Distribution of Crystals in Titania Enamels Fired Directly on Steel

A new technique for studying the crystalline material in fired enamel is described. Using this technique, it was found that the main difference in the crystalline nature of enamel coatings is the presence of FeO crystals at the interface of good bond specimens and the absence of FeO at the interface of poor bond specimens. The effect of certain processing treatments on FeO formation is discussed briefly.     

Studies on corrosion resistant properties of inhibitive primed IPN coating systems in comparison with epoxy-PU systems

Though blending polymers to obtain high performance materials is an old practice, the new trend in such an approach is the emergence of interpenetrating polymer networks (IPNs) as binders for protective coatings with improved properties. In this study, one ambient curing IPN-type polymer alloy developed out of epoxy and acrylic polyurethane systems as a high performing binder was formulated into paints and evaluated in comparison with the currently used conventional epoxy polyamide and polyurethane systems. A three-coat system consisting of a zinc phosphate primer, a micaceous iron oxide (MIO) undercoat, and a topcoat was formulated out of the IPN along with a similar system of epoxy primer, epoxy undercoat, and a PU topcoat. A two-coat system of the same primer with an IPN clear topcoat and a similar system with epoxy has also been studied. All the systems were studied under accelerated laboratory tests and field tests at a corrosive location. The results are reported and conclusions are drawn in this article.
