Vapor-phase rust prevention paper "Stealth" has moderate volatility and exhibits rust prevention effects immediately after packaging. Long-term rust prevention effects can be achieved. The particularly popular "Stealth: with laminate" features an outer laminated surface that acts as a barrier, concentrating the vaporized rust inhibitor inside the packaging, significantly enhancing the rust prevention effect. Additionally, the laminated surface provides moisture-proof and water-repellent effects, effectively protecting important products from humidity and moisture. The strength of the rust prevention paper itself is also increased! 【Points for Choosing Laminated Options】 ■ Concentrates vaporized rust inhibitors on one side to enhance rust prevention effects! ■ The outer laminate strongly guards against moisture and water intrusion! ■ Lamination makes it more resistant to tearing! ■ Can serve as a simple barrier packaging! ■ The laminate also prevents oil from seeping out from the inside of the paper to the outside! ★ Please download the product catalog from the link below to view it. ★ If you would like a sample, please feel free to contact us!

Many domestic rust-proof papers for iron and steel contain nitrites (Na), but due to the potential generation of highly carcinogenic substances, some overseas companies, including those in Europe, are requesting a review of the use of rust-proof paper containing nitrites. In response, our company has newly developed "Non-nitrite Rust-proof Paper: Stealth," which does not contain nitrites. This product provides peace of mind in case the conventional rust-proof paper can no longer be used. 【Proposal from Yamai Processing Paper】 ■ 1. We are currently accepting applications for paid samples for effectiveness verification! When switching occurs, there are risks of time, cost, effort, as well as compatibility risks with metals and the risk of delays in delivery. "Is the effectiveness of non-nitrite rust-proof paper reliable?" "I want to verify the effectiveness with samples for future switching!" For those interested, we offer a small quantity of samples for rust-proof testing at a cost. ■ 2. We are currently offering free informational materials on "Non-nitrite Rust-proof Paper"! These materials explain the risks of rust-proof paper using nitrites and the necessity of switching to "Non-nitrite Rust-proof Paper." * The materials can be viewed via "PDF Download." * If you would like samples, please feel free to contact us!

"SD-B-003" is a powdered adsorbent that captures sulfur gas emitted from packaging materials such as cardboard, preventing corrosion of electronic components during transportation and storage. Unlike volatile rust inhibitors, it does not form a rust-proof film on metal surfaces, allowing it to protect copper-based electronic components without affecting their conductivity. [Features] ■ Simply place it with the product during packaging ■ It has a proven track record in sulfur gas countermeasures for seismographs and telephone exchanges ■ Can be used for sulfur gas countermeasures with various materials such as cloth and plastic *You can view the catalog of rust inhibitors we handle by downloading the PDF. *If you would like a sample, please feel free to contact us!

Our product, 'SD-B-003', is a powdered adsorbent that captures sulfur gas emitted from packaging materials such as cardboard, preventing corrosion of silver and copper. Artworks and cultural properties made of silver and copper can corrode over time, leading to degradation and damage, which may compromise their aesthetic value. By including this product when packaging with cardboard, it effectively adsorbs sulfur gas and protects the products from deterioration. 【Features】 ■ Simply place it together with the product during packaging ■ Proven track record as a sulfur gas countermeasure for seismographs and telephone exchanges ■ Free samples are available *You can view the catalog of our rust prevention agents by downloading the PDF.

"SD-B-003" is a powdered adsorbent that can protect equipment and facilities from corrosive gases and enhance rust prevention effects. ■ Types of gases that can be adsorbed and their adsorption amounts (theoretical values) - SO2 (sulfur dioxide) 12–16g/100g - CO2 (carbon dioxide) 7–11g/100g - H2S (hydrogen sulfide) 6–10g/100g - NH3 (ammonia) 6–10g/100g - H2O (water) 8–10g/100g * The adsorption amounts are theoretical values for each gas when adsorbed individually. ■ Expected applications 1. Transportation and storage of electronic, mechanical, and electrical equipment and parts → Semiconductor manufacturers, electronic component assembly manufacturers, etc. 2. Electrical control panels, electrical equipment, and distribution boards in harsh environments → Communication equipment and other lifeline facilities 3. Areas that produce corrosive gases (volcanic regions, hot spring areas) → Museums (issues with corrosion of artworks), etc. 4. Factories that artificially generate corrosive gases → Chemical and fertilizer factories, paper mills, steel mills, etc. * For more details about the product, please refer to the catalog available for "PDF download." * If you would like a sample, please feel free to contact us!

There are several factors that cause metals to rust, but "the rust on that metal may be caused by corrosive gases." When it comes to corrosive gases, one might think of volcanic gases produced in sulfur hot springs or exhaust gases from cars and forklifts. However, there are actually sources nearby that can generate reducing sulfur as well, such as paper, cardboard, wood, packaging materials, rubber, and lubricants. Everyday packaging materials can also be affected by corrosive gases that cause rust. Therefore, simply storing electronic components and automotive parts puts them at risk of rusting. To reduce the impact of rust caused by corrosive gases and to protect metals and resins from rust, "sulfur gas adsorption sheets" are suitable. With sulfur gas adsorption sheets, you can use them even for electronic components and semiconductors where vapor-phase rust prevention paper cannot be used. ◆ We are currently offering a document that clearly outlines rust prevention measures for various metals. ◆ * For more details, please download the document or feel free to contact us.
