Anti-corrosion varnish - Monoguard Clear

Application:

Thanks to the above properties, Monoguard Clear anti-corrosion varnish is ideal for protecting, among others:

• metal structures: flyovers, pipelines, towers, supports
• external cladding: silos, tanks in production plants, refineries
• small metal elements: railings, fences, barriers, racks, doors
• equipment: construction cranes, tankers, trailers, salt spreaders, containers, etc.

Adhesion of Monoguard Clear to ferrous and non-ferrous metals:

Adhesion to ferrous metals:

Monoguard Clear anti-corrosion varnish has excellent adhesion to ferrous metals—steel and cast iron—similar to Monoguard anti-corrosion paint.

The adhesion of Monoguard Clear increases over time. Weeks and months after application, the innovative ingredients inside the coating continue to increase the bond, reaching levels of up to 17 MPa / 2500 PSI when performing a pull-off test in accordance with ISO 4624 (substrate adhesion test). These values significantly exceed the 7 MPa / 1000 psi regularly required by many industry specifications.

The excellent adhesion of Monoguard Clear also actively contributes to the protection of steel against corrosion. Because the coating adheres so well to the surface, it is more difficult for rust to begin its damaging expansion. The bond works so well that rust simply does not have enough strength to push the coating away and come into contact with the bare metal surface to which Monoguard Clear has literally bonded itself.

This is also a big advantage in the event of local damage to the coating, as rust will not be able to spread easily.

* Note on the application of Monoguard Clear varnish to clean black steel and cast iron:

The following note applies only to application on non-corroded ferrous metals (steel, cast iron). It does not apply to application on non-ferrous metals (aluminum, copper, zinc, stainless steel, etc.).

Monoguard Clear varnish is a water-based product. When applied to non-corroded cast iron and steel, the water evaporating from the varnish may activate rust. This means that small rust spots will appear immediately after painting. To reduce this risk, do not apply the varnish in high humidity conditions. Steel should also not be sandblasted before applying the varnish. Sandblasting activates the steel and increases the risk of rust spots after applying water-based varnish. In addition, we recommend using RD-Eco PowerClean to clean steel, which, thanks to additives that prevent rust formation, reduces the formation of small rust spots after cleaning the steel and during varnish application.

If you want to achieve a rust-free effect on ferrous metals, we always recommend testing the paint on a smaller element to confirm that the painting technique allows this.

** Adhesion to non-ferrous metals:

For non-ferrous metals, Monoguard Clear anti-corrosion paint has excellent adhesion to galvanized steel and stainless steel. For other metals, such as copper or aluminum, special substrate preparation may be required for best adhesion.

Detailed information is provided in the tables below.

Key:

• GT is the result of testing using the Cross Cut method;
• The best adhesion is GT0. The following numbers (1, 2, 3) indicate poorer adhesion (the higher the number, the poorer the adhesion);
