"AR-PRIMER 12.5" is an inorganic rust-proof primer designed for repairing rust on steel materials and protecting newly installed steel frames from rust. It is composed of a polymer cement mortar system made from emulsions and compounds, and it has a wide temperature resistance range of -100 to 200°C. Additionally, it contains carbon fibers to enhance strength, and the coating blocks exposure from the outside, protecting the steel materials. 【Features】 ■ Rust and corrosion resistance - Suppresses long-term corrosion and re-corrosion of steel materials - Achieves reduction in repair costs for steel structures, etc. ■ Workability - Shortens construction processes and reduces repair costs for repainting, etc. - Contributes to construction quality management *For more details, please refer to the PDF document or feel free to contact us.

This document is a collection of case studies for 'AR-PRIMER 12.5', which consists mainly of a compound made of cement and silica sand, and an emulsion made of special polymers, containing carbon fibers to enhance surface strength. By using it in conjunction with protective coatings as an anti-rust primer for various metal components, including steel frames, cubicles, and steel pipes, the anti-rust effect is significantly improved. It includes photographs of case studies such as "repairs in the machinery room" and "repairs and heat insulation of corrugated roofs" in food processing plants. We encourage you to take a look.

This document is the construction manual for 'AR-PRIMER 12.5', which is used for rust repair of steel materials and protecting new steel structures from rust. It is an inorganic rust-proof primer made of polymer cement mortar consisting of an emulsion and a compound, containing carbon fibers to enhance surface strength. The surface film blocks various exposure phenomena from the outside, protecting the base material while also providing a wide temperature resistance range of -100°C to 200°C. The "Construction Procedure" section provides detailed explanations along with numerous photographs. Please take a moment to read it.

This document introduces the inorganic rust-proof primer "AR-PRIMER 12.5," which is applied on-site by mixing and stirring a compound mainly composed of cement and silica sand with an emulsion made of polymer and moisture. Due to the strong alkalinity of the main component, it transforms the surface of iron that has developed red rust into black rust, forming a stable rust-proof layer. Since the surface preparation typically involves a three-step scraping process without the need to strip existing paint, significant savings on scraping costs can be achieved. We provide detailed explanations on "construction procedures," "rust-proof methods," and "points to note during construction." We encourage you to read it.

Cubicles are essential in buildings and factories that use large amounts of electricity. Steel structures require specifications that can withstand rust in harsh environments, including humidity, coastal salt-laden winds, and exhaust gases. To prevent rainwater intrusion from rusted areas and further rust progression, we recommend timely and appropriate rust repairs. AR-PRIMER 12.5 is a rust-proof primer that can be applied over red rust. It is an inorganic rust-proof primer containing carbon fibers. NETIS: KT-170078 Features of AR-PRIMER 12.5: pH value: approximately 12.5 The strong alkaline coating passivates red rust and suppresses long-term re-corrosion of steel materials. Labor-saving surface preparation. Three types of surface preparation (depending on the condition, a mix of types 2 and 3 may be used). Environmental and safety considerations. Inorganic rust-proof primer. Meets JWWA standards for water quality testing. Complies with Marpol (International Convention for the Prevention of Pollution from Ships).

We would like to introduce a case of rust repair in the machinery room at a food processing factory. In the past, regular repainting covered the underlying rust with surface paint, which allowed the residual rust beneath the paint film to progress and cause blistering. Once the multiple layers of existing paint were removed, the substrate was covered in red rust, indicating a state of overall corrosion. Therefore, we applied 'AR-PRIMER 12.5' to convert the red rust to black rust and stop the progression of the internal residual rust. For large areas, we used spraying, while for finer areas such as handrails, we used brushes and rollers. 【Effects】 ■ Converts red rust to black rust and stops the progression of internal residual rust. ■ With a durability of over 20 years, it significantly reduces the time and cost associated with regular repainting. *For more details, please refer to the PDF document or feel free to contact us.

The steel surfaces of cubicles and generators installed outdoors are very prone to rusting. The surface is originally protected by paint, but deterioration such as chalking and peeling, along with the effects of rainwater and humidity, makes it susceptible to rust. Therefore, we applied 'AR-PRIMER 12.5', which has excellent rust and corrosion resistance and durability of the coating, using a trowel. 【Features of AR-PRIMER 12.5】 ■ Contains carbon fibers to increase surface strength ■ Forms a stable rust-proof layer that suppresses corrosion and re-corrosion of steel ■ The coating has excellent elasticity and adhesion, providing long-term rust prevention effects ■ Two-color application in gray and green prevents missed spots and contributes to quality control of the application ■ Contributes to reducing repair costs for metal components such as steel structures *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of rust repair on a generator. The lower part of the generator has rusted further due to rainwater intrusion from above, with holes on the outside revealing the insulation inside. The inner metal is rusted and flaking, and the rust continues to progress. Therefore, we applied 'AR-PRIMER 12.5', which allows excess moisture to escape until fully cured and transforms red rust into stable black rust with an alkaline coating. [Repair Points] - Prevent rainwater intrusion from above - Seal rust holes exposing insulation - Ensure a dry film thickness of 650 to 800 microns for heavy corrosion protection *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of repairing and heat-insulating a corrugated metal roof at a factory. The surface was prepared through scraping and high-pressure washing, followed by the application of 'AR-PRIMER 12.5' via spraying. Heat-insulating paint was then applied. The temperature of the corrugated metal before the work was 58.7℃, but after applying our product, it dropped to 47.9℃, and after applying the heat-insulating paint, it further decreased to 35.4℃. 【Construction Overview】 ■ Surface preparation through scraping and high-pressure washing (Before construction corrugated metal temperature: 58.7℃) ■ Spraying of AR-PRIMER 12.5 (After construction corrugated metal temperature: 47.9℃) ■ Application of heat-insulating paint (After construction corrugated metal temperature: 35.4℃) *For more details, please refer to the PDF document or feel free to contact us.

Here is an example of a newly constructed steel anti-corrosion project at a temple. The kitchen of Zuiseiji Temple was designed by Kengo Kuma & Associates. To protect the steel from rust while also preventing rust on the solid cypress rafters, we applied 'AR-PRIMER 12.5'. **Features of AR-PRIMER 12.5** - Contains carbon fibers to increase surface strength - Suppresses corrosion and re-corrosion of steel materials by forming a stable anti-corrosion layer - The coating has excellent elasticity and adhesion, providing long-term anti-corrosion effects - Two-color application in gray and green prevents missed spots and contributes to quality control during construction - Contributes to reducing repair costs for metal components such as steel structures *For more details, please refer to the PDF document or feel free to contact us.*
