Research on rust prevention was already being conducted in 1942 at the Cambridge Metallurgical Institute in the UK, and it was found that to achieve rust prevention equivalent to that of zinc plating, more than 95% zinc was required in the dry paint film. The Robal series is a high-concentration zinc powder coating (zinc-rich paint) designed based on this knowledge, containing as much as 96% zinc powder in the Robal and Epobal coatings. (However, Robal Silver is designed with a zinc content of 83%, and Robal Alpha with 92%.) Therefore, when the Robal series is applied, it creates a zinc coating with electrical conductivity similar to that of zinc plating, with zinc acting as a sacrificial anode to protect the iron from rust. This rust prevention method of the Robal series has the characteristic that rust does not spread from even the smallest pinholes or scratches in the coating.

Additionally, it can also be finished with a single coat as a corrosion-resistant base. 【Features】 ■ 93% VOC reduction ■ 93% zinc content ■ Odorless ■ Liquid + powder type ■ Color: Gray *For more details, please refer to the PDF document or feel free to contact us.

Cold zinc plating "ROVAL" enhances the zinc content in the dry coating to 96%, providing rust resistance equivalent to that of hot-dip galvanizing. Additionally, it can be applied at room temperature regardless of location, which is why it is referred to as "cold galvanizing" in contrast to hot-dip galvanizing. It is not only effective for rust prevention and repair of zinc plating on iron but also extends the lifespan of aging zinc coatings. ROVAL has been used in various fields for over 50 years. For more details, please download the catalog.

"Thick Film Robal" is a thick film type of room temperature zinc coating that does not require multiple coats. Since there is no need for re-coating, work time can be significantly reduced. It achieves the recommended film thickness of 80μm in one coat, whether applied with a brush or through airless spraying. This minimizes time loss even in situations where road construction requires closures or machinery must be stopped for maintenance. 【Features】 ■ Thick film type that does not require re-coating ■ Significant reduction in work time ■ Rust prevention effect equivalent to HDZ55 ■ Compliant with RoHS directive ■ Formaldehyde emission rating: F☆☆☆☆ *For more details, please refer to the PDF document or feel free to contact us.

When cutting or welding galvanized components, the coating in those areas can peel off. By using Robal, you can easily repair the peeled areas and prevent rust. Especially at cut edges and welds, it is difficult to achieve a sufficient film thickness, so applying two coats properly is the key to the repair. 【Case Overview】 ■ Coated Area: Grating (Drain Cover) ■ Product Used: Robal / Robal Alpha ■ Repair Point: Apply two coats to achieve the desired film thickness *For more details, please refer to the PDF document or feel free to contact us.

Rust inevitably occurs on the steel frame parts that were painted with general paint. To prevent rust from occurring in the future, we will introduce a case where rust and old paint were removed, and two coats of Robal were applied for repainting. The key point in repainting is that, even if it is a rust prevention paint from another company or an active film, it is important to use power tools to remove it and expose a clean steel surface. Ten years have passed since the construction, and no rust has occurred. 【Case Overview】 ■ Painted Area: Steel frame of the awning part of a logistics warehouse ■ Product Used: Robal ■ Repainting Key Point: Remove rust and old paint to expose the metal surface *For more details, please refer to the PDF document or feel free to contact us.

In 1995, approximately 10 years after its completion, repair work was carried out on the lighting columns of the Great Naruto Bridge. Here is an introduction to that case. The lighting fixtures illuminating the road on the bridge were originally galvanized, but due to the harsh environment, the zinc was consumed rapidly, leading to the occurrence of spot rust. As a rust prevention measure, a product called Robal was used for repairs in the areas of the lighting fixture mounting and the base, which required particular strength. Even during a site inspection eight years after the work, no rust was observed. 【Case Summary】 ■ Before Construction - Due to constant exposure to sea breezes, zinc consumption was severe, resulting in spot rust. ■ Eight Years Later - After applying Robal over the galvanized surface, there was no rust occurring in the repaired and extended areas. *For more details, please refer to the PDF document or feel free to contact us.

In October 2002, we would like to introduce a case of large-scale refresh work that involved closing the Hanshin Expressway for seven days. The main work consisted of pavement and joint repairs, but Global products were used for the repair of signposts and gate pillars (longevity painting). Zinc-coated structures, over several decades and in harsh environments, experience surface oxidation, peeling, and thinning. For the next project, which is scheduled 15 years later and aims to be maintenance-free, Global's high rust prevention performance was trusted and adopted. [Case Overview] ■ Before Painting - The surface was dirty from exhaust gases, and rust had developed. ■ After Painting - Global was used for the primer, and Global Alpha was used for the topcoat. - Achieved high rust prevention performance and a beautiful finish. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of the renovation painting of a multi-story parking lot. Many of the galvanized components used in multi-story parking lots have a thin coating, which can lead to rust developing within a few years. After removing the rust, applying a coating of Robal over the entire surface provides the same effect as re-galvanizing, protecting the multi-story parking lot from rust for an extended period without maintenance. Additionally, the process involves fewer steps and has quick-drying properties, allowing for handover within a day, thus reducing the burden on construction and the inconvenience for residents. 【Benefits of Implementation】 ■ Easy to schedule - Flexibly accommodates changes in the construction schedule due to weather and other factors. ■ Reduced burden and costs for residents - Reduces the burden on residents, as well as costs such as labor, scaffolding, and alternative parking during the construction period. ■ Maintains the aesthetic appeal of the building over a long period, protecting its important asset value as a property. *For more details, please refer to the PDF document or feel free to contact us.
