Danjiora E Primer Selected as Recommended Technology by Japan Ministry of Land, Infrastructure and Transport

Danjiora E Primer: A New Era in Corrosion Protection

Japan Paint Co., Ltd., headquartered in Shinagawa, Tokyo, has announced that its product, Danjiora E Primer, has been selected as a recommended technology by the Ministry of Land, Infrastructure and Transport (MLIT). This recognition was made official through the Japanese government's New Technology Information System (NETIS), categorizing it as one of the groundbreaking technologies for the fiscal year 2026, specifically on April 27, 2026. The NETIS registration number for this product is CG-250006-A.

The NETIS serves as a crucial database that promotes the utilization of innovative technologies in public construction projects. Danjiora E Primer was registered with NETIS on September 30, 2025, due to its high barrier properties and exceptional corrosion resistance, which simplify substrate preparation and reduce lifecycle costs while improving anti-corrosion quality. Consequently, it contributes to minimizing constraints during construction.

Every year, the MLIT evaluates these registered technologies, choosing the most pivotal and useful innovations as "recommended technologies," "pre-recommended technologies," and "technologies promoting evaluations," based on assessments from external experts. The selection of Danjiora E Primer as a recommended technology highlights its significant potential to enhance the quality standards of technological applications in public works.

A key feature of Danjiora E Primer is its high barrier function, which effectively inhibits the intrusion of corrosive factors. Additionally, the product boasts a "rust conversion function" that allows for rapid transformation into a stable structure when applied on rusted surfaces, showcasing superior corrosion protection. The primer can even tolerate residual salt on surfaces up to three times the level allowed by conventional specifications, resulting in significant reductions in the time required for washing prior to application.

Moreover, since Danjiora E Primer can be applied directly onto rusted surfaces, the overall time needed for substrate preparation is dramatically shortened. This not only extends the repainting cycles of infrastructure but also shortens project timelines, providing additional benefits in terms of efficiency and cost savings.

As technologies designated as recommended have increased applicability in public works, contractors utilizing this technology can expect to receive enhanced scores in terms of overall evaluations and construction performance when compared to usual NETIS-registered technologies. This presents tangible benefits for both clients and contractors seeking to implement advanced methods of construction.

Japan Paint Co., Ltd. continues its commitment to develop products and technologies that address social issues through the maintenance and management of social infrastructure. By focusing on innovative solutions, they aim to further enhance the frameworks affecting the construction sector.
