ROVAL has a 96% zinc content in the dry film. Anti-corrosion performance is equivalent to hot-dip galvanizing.
High temperature is required for hot-dip galvanizing. However, ROVAL cold galvanizing can be performed even at room temperature. Ready-to-use ROVAL cold galvanizing has been used in Japan for more than half a century in the restoration of worn hot-dip surfaces and in the protection of metal surfaces such as steel against corrosion.
Anti-Corrosion Mechanism
ROVAL cold galvanizing product shows high anti-corrosion performance with high electrochemical reaction properties of zinc.
ROVAL protects steel against corrosion with its electrochemical reaction property of Zinc. Zinc provides cathodic protection on the metal surface by direct contact. The electrochemical reaction prevents the rust from seeping under the ROVAL film even if rust is formed on the damaged or finely coated surface.
Normal paints provide protection against water / air on the metal surface. If the paint layer is damaged or spilled, rust will reappear. The rust layer formed spreads from the bottom of the paint to the other regions.
Maintenance
ROVAL can be applied directly to the surface only after the rust formed in the damaged area is removed. The new layer applied fuses with the old layer regardless of the time passing. A different layer does not occur. This significantly reduces maintenance costs.

RUST BULLET
RUST BULLET
- The free-swelling rust layers on the surfaces should be removed by coarse blasting and / or cleaned with a wire brush.
- Any old paint layers on the surface, if any, should be cleaned mechanically and / or with the aid of chemical solvents.
- RUST BULLET METAL BLAST should be applied by spraying on surface for free corrosion and / or cleaning of soluble salt, oil, etc. on the metal surface after paint cleaning. After waiting for a while, the solvent should be removed from the surface using warm deionized water.
- After this necessary preliminary procedure for surface preparation and cleaning which increases the success of the application and makes the service life of the product to be stable is completed, RUST BULLET STANDARD should be applied in two coats with the help of brush and / or roller. If a roll is to be used, it is recommended to use a short pile roller. The product should be applied to the surface by the method of forming equal amounts of parallel cross lines without forming agglomeration in a region. The first coating layer should be applied a little bit plentiful. The second and other additional layers are applied to completely cover the first layer. Before the application of second layer of RUST BULLET STANDARD, the previous layer must be in dry touch. Drying time between coating layers is about 2-4 hours. Drying time may vary depending on surface temperature and relative humidity. Sometimes this period can go down to 1.5 hours. The product is sensitive to moisture. Under high humidity conditions of 80% or more, the product will dry faster. If a 24 hour application period has elapsed, the surface should be slightly abraded with at least 150 grift of material to ensure proper adhesion of an overcoat. If the second coat is to be applied the next morning, make sure that there is no dew or condensation on the previous coat. The application surface must always be dry. For optimum performance, it must be ensured that corners, edges, and hollow areas are sufficiently covered.
- RUST BULLET STANDARD, the paint which is applied directly on rust, also serves as a topcoat. It provides a metallic gray finish. If a different color is desired for an aesthetic finish, RUST BULLET COLOR SHELL can be applied in 2 coats over the paint thrown directly on the rüşt.
