We have launched a specialized information site about black dyeing agents for black dyeing processing of steel.

Shortened delivery times, significant cost reductions, and stable quality management. In both steel and casting, in-house black dyeing processing is possible.

The "Semi-Automatic Blackening Machine" is a set of blackening equipment and chemicals that allows for in-house processing of tools and steel parts with genuine blackening. ■□■ Do you have any of these concerns? ■□■ - Occurrence of red rust due to incomplete rinsing - Quality issues such as insufficient blackening film due to improper boiling By automating the management of the concentration and temperature of the blackening solution with a computer, blackening processing can be performed easily and without failure, which previously required constant supervision. 【Main Features】 - No color variation, consistent with the gloss of the material itself. A durable blackening film of magnetite (Fe3O4) can be created. - The film thickness is about 1μm, which does not affect dimensional accuracy. - The film is wear-resistant and does not peel off or discolor when rubbed. - The film retains rust preventive oil, providing excellent rust prevention (for indoor use). - The treatment solution can be reused repeatedly without disposal, making it economical. - The wastewater used for rinsing can be discharged after neutralization with acid. - The entire process can be completed in about 15 to 20 minutes. For more details, please contact us or download the catalog.

Just immerse the degreased workpiece at room temperature for 1 to 3 minutes! You can achieve blackening of steel.

"Instablack 333" is a room temperature black dye that does not require wiping. This product allows for black dyeing of steel by simply immersing degreased workpieces at room temperature for 1 to 3 minutes. Additionally, it does not leave any smudges, making it possible to incorporate the black dyeing process into an automated line. The black dye layer is extremely thin (approximately 0.2μm) and does not affect dimensional accuracy. Improving and stabilizing black dyeing quality! ■ We want to improve and stabilize black dyeing quality ■ Early red rust, color unevenness, bubbles, etc. Audeck offers solutions to these problems.

Concentrated type usable for both immersion and coating. For steel and cast iron up to HRC50. For blackening machine parts, repairs, and blackening of tools and jigs (used diluted 5 to 8 times).

The chemical reaction at room temperature finishes steel components in the same black color as alkaline heating blackening. High Black has a fast reaction speed, allowing for not only immersion but also blackening finishes and repairs of assembled machine parts, as well as blackening large steel products that cannot fit into a tank through application or spraying.

Steel, aluminum, stainless steel, copper, brass, and more can be easily "blackened" with a spray.

The "Easy Black Dye Spray Black Seal" forms a genuine "matte" black coating of about 5 to 10 μm just by spraying it on surfaces such as steel, aluminum, stainless steel, copper, and brass. It is resistant to corrosion and water, and is not affected by petroleum solvents or oils (it is not resistant to thinner-based solvents). Additionally, it provides rust prevention for about six months (indoors). Please make use of it for a wide range of applications such as black dyeing of small parts, repairs, prototype production, black dyeing after assembly, and pinhole repairs after black anodizing.

We have newly added a **"Frequently Asked Questions Q&A"** section to the Hyper CLT sheet website. It clearly summarizes many questions frequently asked by those considering the introduction of the product, such as "What types of civil engineering sites can it be used on?", "Can it be used on rainy days?", "Is it compatible with large machinery?", and "What is NETIS?". The Hyper CLT sheet is a lightweight wooden sheet utilizing wood CLT, suitable for a wide range of applications including temporary roads, access routes, and heavy machinery work yards. It is also registered as a **Ministry of Land, Infrastructure, Transport and Tourism NETIS registered technology "TH-250021-A"**. Since it is a new material, we will not leave any uncertainties unaddressed. We aim to create a website that makes it easy to resolve questions before introduction, including information on wood, NETIS, civil engineering, and CLT, and we will continue to enhance the Q&A section.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.
