Roval VS. Hot Dip Galvanizing

Roval VS. Hot Dip Galvanizing

ROVAL‘s anti-corrosion performance is equivalent to the highest quality hot-dip galvanizing available in Japan.
In order to compare the anti-corrosion performance of ROVAL with the hot-dip galvanizing process, corrosion accelerating tests were conducted in accordance with the Japanese Standard JIS H8502-1999 in the Japan Paint Inspection and Testing Association.
The results and pictures from the test show that ROVAL has a performance equivalent to that of hot-dip galvanizing.
ROVAL has been certified by the Construction Technology Council Certification Center in Japan as equivalent to hot-dip galvanizing.
• JIS H8502-1999 is based on ISO Standards 4540,4541,8407,8565,9227 and 10062.

Miyakojima Island Test Area

Miyakojima Island is located in the southern part of Japan, roughly at the same latitude as Florida, USA. The island is a place where high temperatures, humidity and salt content, strong sunlight and UV effect can be used to test the deterioration due to bad weather conditions.

Roval Vs. Other Anti-Corrosion Paints

Roval Vs. Other Anti-Corrosion Paints

ROVAL has the characteristics that prevent the formed rust from passing under the application layer.
On the Miyakojima island of Japan, ROVAL and other competitors’ anti-corrosion paints were exposed to atmospheric conditions at the center where deterioration from bad weather conditions was tested for 36 months.

The results show that; While ROVAL protects steel surfaces against the spread of rust by electrochemical reaction, other products have not prevented the spread of rust from cross-scratched parts to other surfaces.

Roval and Anti-corrosion Mechanism

Roval and Anti-corrosion Mechanism

ROVAL is a cold galvanizing product with high anti-corrosion performance, providing equivalent protection to hot galvanizing.roval_5ROVAL has a 96% zinc content in the dry film. roval_1a roval_1 roval_2

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.

ROVAL Products Color Change Under Weather Conditions

Roval products have the same properties as galvanized materials exposed to weather conditions. These characteristics make the repair invisible.

RUST BULLET

RUST BULLET

  1. The free-swelling rust layers on the surfaces should be removed by coarse blasting and / or cleaned with a wire brush.
  2. Any old paint layers on the surface, if any, should be cleaned mechanically and / or with the aid of chemical solvents.
  3. 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.
  4. 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.
  5. 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.
