The "Room Temperature Zinc Coating ZRC Method" is a technique used to protect steel members, such as large structures, thin sheet products, and bridge girders, from rust where hot-dip galvanizing is difficult to apply. By applying a one-component liquid mixture called "ZRC," which contains 95% high-concentration zinc in a dry film with a thickness of 81μm or more, it exhibits rust prevention equivalent to hot-dip galvanizing (JIS H8641 HDZT77). The effectiveness can be maintained over a long period, and in a survey conducted in November 2022 on a part of the Kamoike Ohashi Bridge in Yokohama City, which opened in October 2003 (underneath the floor slab and stairs), there was no peeling or rust formation, maintaining a state that has not required repairs for over 19 years. **Features of the Room Temperature Zinc Coating ZRC Method:** - No immersion in a zinc plating bath is required, allowing for application to large components in factories or on-site. - Since it is applied at room temperature, it can be used on thin products that may warp due to high-temperature processing. - Corrosion resistance performance equivalent to hot-dip galvanizing has been confirmed through outdoor exposure tests (5 years in Miyako Island). - Long-term durability is achieved through electrical conductivity within the coating. Repairs, renovations, and re-coating are also easy. - Free design options are possible with the use of dedicated topcoats in colors like red and blue. ★ Case study materials can be viewed from the "PDF Download."

The "Room Temperature Zinc Coating ZRC Method" is a technique for protecting steel components, such as large structures, thin sheet products, and bridge girders, that cannot undergo hot-dip galvanizing from rust. By applying a one-component liquid mixture called "ZRC," which contains 95% high-concentration zinc, with an average dry film thickness of 81μm or more, it exhibits rust prevention performance equivalent to hot-dip galvanizing (JIS H8641 HDZ55). There is a wealth of adoption records in major organizational design offices and atelier-style design offices. The ZRC method will solve the concerns of architects and designers. 【Features】 ■ No immersion in a zinc plating bath is required, allowing for application to large components in factories or on-site. ■ Since it is applied at room temperature, it can be used on thin products that may warp due to high-temperature processing. ■ Corrosion resistance performance equivalent to hot-dip galvanizing has been recognized through outdoor exposure corrosion resistance tests (5 years in Miyako Island). ■ Long-term durability is achieved through electrical conductivity within the coating.

"Z.R.C." is a room temperature zinc coating agent that ensures durability and corrosion resistance equivalent to hot-dip galvanized JIS H8641 HDZ55 (550g/m2) by applying a dry film thickness of 76μm or more to steel members that have undergone surface preparation. By eliminating the need for a zinc plating bath, it can be easily applied not only in steel fabrication factories but also at construction sites for joints and other areas. By performing the application at room temperature without immersion in a zinc plating bath (treatment temperature 450-480°C), it does not impose any constraints on design, fabrication, or construction. [Features] - The rust prevention principle is the same sacrificial anode action as hot-dip galvanizing. - Repairing the zinc layer is as easy as painting. - By applying a thickness of 76μm or more, durability and corrosion resistance equivalent to hot-dip galvanizing (JIS H8641 HDZ55) can be achieved. - By selecting the topcoat material, color planning can be done freely. *For more details, please refer to the PDF document or feel free to contact us.

"AQUA RUS STOP" is a water-based rust conversion paint. By applying it directly onto red rust, it converts the red rust into black rust, preventing further progression of rust. This makes rust removal easier, and the coating forms a water-based layer in addition to the layer converted to black rust. Furthermore, it is a water-based single-component paint that contains no harmful substances, making it a material that can be stored long-term under stable environmental conditions. 【Features】 ■ Being water-based, it is considerate of human health and the environment ■ Can be top-coated with water-based or oil-based paints ■ Of course, it can also be painted on surfaces with old coatings other than red rust and on steel surfaces ■ Dilution and cleaning of tools can be done with tap water, making it simple and safe ■ Available in two colors: "Black" and "Silver" *For more details, please refer to the PDF document or feel free to contact us.

The coating of room temperature zinc plating Z.R.C. contains small high-grade zinc particles that are surrounded and supported by larger high-grade zinc particles, creating a structure. This internal mechanism, which is not found in general-purpose products, is a significant factor in the excellent coating of room temperature zinc plating Z.R.C. Furthermore, within the coating of room temperature zinc plating Z.R.C., a high-end special proprietary binder, which is also a crystallization of years of technology, fills the slight spaces between the small and large zinc particles without any gaps. 【Features】 ■ By strongly reinforcing both small and large zinc particles, it maintains heat resistance, adhesion, strength, etc., for a long time, preventing general-purpose products from competing. ■ The total surface area of the small and large zinc particles is overwhelmingly vast compared to general-purpose products. ■ Within the room temperature zinc plating Z.R.C. coating, intermittent electrical conduction occurs, maintaining exceptional rust resistance that can withstand harsh environments for extended periods. *For more details, please refer to the PDF document or feel free to contact us.
