Multi-functional aqueous solution "SEA'S 7"

**Notice of AIXIA Expo Participation** Seven Corporation will be exhibiting at the AIXIA Expo. At our booth, we will introduce our environmental solution "SEA'S7 Strong Type," born from water. In recent years, reducing the use of thinners and organic solvents, addressing VOCs, and improving the working environment have become important themes in manufacturing sites. However, advancing environmental measures while maintaining cleaning power, rust prevention performance, and productivity is not easy. SEA'S7 addresses these challenges through applications such as: - Improvement of cleaning and degreasing processes - Alternatives to thinners and parts cleaners - Improvement of coolant fluids - Rust prevention measures - Maintenance of equipment and tools At the exhibition, we will present methods for utilizing SEA'S7 to tackle various challenges, along with actual case studies and evaluation data. If you are facing concerns such as: - "I want to advance environmental measures" - "I want to reduce the use of organic solvents" - "I want to balance site improvements and cost reductions" We invite you to visit our booth. We sincerely look forward to your attendance.

SEA’S7 is a water-based cleaning agent that can be filled into gardening spray devices or commercially available spray bottles, and it is increasingly being adopted on many sites as an alternative to parts cleaners. Instead of "dissolving" oil stains, it uniquely "breaks down and peels off" them, demonstrating high degreasing performance while suppressing reattachment. It can be safely used on metal and plastic parts, and its low odor contributes to improving the working environment. Compared to conventional solvent-based cleaners, it has a lower risk of ignition and excels in terms of safety. It has already proven effective as a substitute for thinner in the parts cleaning and pre-treatment processes in the manufacturing industry, and it is evaluated from the perspectives of cost, safety, and environmental compliance. Its ease of use, simply by spraying, allows for smooth implementation on-site.

We would like to inform you about the strengthening of our supply system and information dissemination as follows. ■ Regarding the enhancement of the SEA’S7 special site and social media To enhance information provision to end users, we have started and strengthened the operation of the SEA’S7 special site and social media. ▼ Special Site https://phenomenal-sawine-5721c9.netlify.app/ ▼ Instagram https://www.instagram.com/seven_corporation_/ ▼ X (formerly Twitter) https://x.com/seven_corpo ▼ YouTube https://www.youtube.com/@SEAS7-r7s/videos We are continuously sharing on-site examples, applications, technical information, and more, so we would appreciate it if you could follow and make use of these resources.

Due to changes in the situation surrounding the Strait of Hormuz, there is renewed awareness of the instability in the procurement and pricing of naphtha-derived solvents. The use of thinners and parts cleaners is currently under review. SEA’S7 is a multifunctional aqueous solution based on components derived from scallop shells and water. Instead of dissolving oil stains, it removes them by breaking them down and peeling them off, addressing degreasing, cleaning, deodorizing, and disinfecting. It is odorless and non-flammable, contributing to improved working conditions and reduced solvent usage. In overseas factories (Mexico), evaluations are being conducted to assess it as an alternative to thinners in the parts cleaning process. Its performance in removing grease has been confirmed even under conditions of approximately 50°C and with the use of ultrasonic cleaning machines, and discussions are ongoing regarding its safety and workability as an alternative. Additionally, in Japan, there are cleaning records for aluminum and copper parts in automotive-related factories, confirming grease removal and wastewater treatment compliance without corrosion. It achieves a cleaning level equivalent to that of thinners while also contributing to reduced environmental impact. With domestic raw materials and production, supply stability is also ensured. It contributes to the review of cleaning processes and risk reduction.
