■Introduction to SeaFect Solution■ SeaFect powder is made from scallop shells sourced from the Okhotsk Sea, which are uniquely processed through a heating method to create a powdered form. This powder undergoes further special processing using proprietary technology, resulting in a natural calcium hydroxide with complex properties that are unparalleled. Calcium hydroxide meets national safety standards and is widely used as a food additive. SeaFect has been confirmed through various tests to have very high effectiveness in disinfection, antibacterial action, and deodorization. Despite being strongly alkaline, it does not cause side effects such as skin irritation, and being derived from natural materials makes it environmentally friendly. Additionally, compared to common similar materials, its unique technology allows for smaller particle size, providing both effectiveness and rapid action. ◇The SeaFect solution is safe and offers a powerful disinfection and deodorization liquid that has never been seen before, as it is made using SeaFect. ◇In virus inactivation tests using bacteriophages, the effectiveness of disinfecting various viruses, including the novel coronavirus, has been evaluated to be equivalent to that of alcohol (80% concentration), despite being non-alcoholic.

"Aqua Shield" is a water-based paint in an aerosol spray form that provides long-term rust prevention. It contains zinc phosphate as a rust-inhibiting pigment, which suppresses the progression of corrosion through the formation of a passive film. It exhibits rust prevention capabilities equivalent to JIS K 5674 Type 2 (lead and chromium-free rust-proof paint) and JIS K 5551 (rust-proof paint for structures). Additionally, it is based on modified epoxy resin, offering high adhesion and compatibility with a wide range of topcoat paints. 【Features】 ■ Environmentally friendly water-based paint ■ Good workability due to spray application ■ Coating with excellent rust prevention and adhesion ■ Suitable silver-gray color for repairs ■ User-friendly quick-drying *For more details, please refer to the PDF document or feel free to contact us.

The sticker and graffiti prevention clear coat "Pio Barrier" is a surface protection material for concrete. When applied to the concrete surface, it penetrates while forming a water-repellent and moisture-proof layer on the surface. It requires no measuring, mixing, or dilution, and the drying time is about 30 minutes (in summer), allowing for quick work! Additionally, the sticker and graffiti prevention clear coat "Pio Miraclean Z" forms a water-repellent and moisture-proof layer on the surface when applied to the substrate, blocking the intrusion of chemicals such as rainwater, chlorides, and carbon dioxide, thereby suppressing deterioration. The lower layer penetrates into the interior, repairing fine cracks (for use on concrete) and maintaining performance for a long time due to excellent adhesion to the substrate. It is also suitable for countering gases such as carbon dioxide and hydrogen sulfide. 【Common Features】 ■ High water-repellent effect, salt damage prevention effect, and long lifespan ■ Inhibits the adhesion of "glue," making stickers easier to remove ■ Inhibits the adhesion of "paints," making them easier to remove *For more details, please download the PDF or feel free to contact us.

The Concrete Keeper series is a concrete impregnation material primarily composed of lithium silicate with the addition of silane. Since it combines lithium silicate as the main component with silane in a single solution, it offers both the permeability and concrete modification effects of silicate-based materials, which were not achievable with previous impregnation materials, as well as the sealing properties of silane-based materials, providing the benefits of both! 【Features】 ■ Quality Improvement Compared to conventional technologies, the water permeability suppression rate has increased, enhancing quality. ■ Excellent Permeability Deeply penetrates the capillaries and voids of concrete. ■ Environmentally Friendly and Safe An odorless, inorganic aqueous solution that does not contain volatile organic solvents, making it safe for use both indoors and outdoors. ■ Process Shortening and Cost Reduction The Concrete Keeper series achieves sufficient effectiveness with just one application! By reducing the application process and amount, it realizes process shortening and cost reduction. *Please download the PDF for the product catalog and comparison materials for impregnation agents.

The anti-sticker and graffiti prevention clear coat "Pio Miraclin Z" forms a water-repellent and moisture-proof layer on the surface when applied to the substrate, blocking the intrusion of chemicals such as rainwater, chlorides, and carbon dioxide, thereby suppressing deterioration. The lower layer penetrates internally, repairing fine cracks (for use on concrete) and maintaining performance for an extended period due to excellent adhesion to the substrate. It is also suitable for countermeasures against gases such as carbon dioxide and hydrogen sulfide. Additionally, the anti-sticker and graffiti prevention clear coat "Pio Barrier" is a surface protection material for concrete that, when applied to the concrete surface, penetrates internally while forming a water-repellent and moisture-proof layer on the surface. It requires no weighing, mixing, or dilution as it is a one-component product. 【Common Features】 ■ High water-repellent effect, salt damage prevention effect, and long lifespan ■ Inhibits the adhesion of "glue," making stickers easier to remove ■ Inhibits the adhesion of "paints," making them easier to remove *For more details, please download the PDF or feel free to contact us.

The Concrete Keeper series is a concrete impregnation material that primarily uses lithium silicate combined with silane. It features a formulation where lithium silicate is the main component, blended with silane. Therefore, in addition to the wear resistance achieved through the permeability and concrete modification effects of silicate-based materials, it also incorporates the sealing properties of silane-based materials, offering the benefits of both! ☆The two main components work together to block concrete deterioration☆ 1. Silane-based ⇒ The silane component forms hydrophobic groups on the surface, providing water-repellent functionality. This helps to suppress deterioration of concrete caused by water. 2. Lithium silicate-based ⇒ Lithium silicate densifies the surface layer of the concrete and reintroduces alkalinity to existing concrete. Compared to traditional techniques that require two coats, this product achieves high values in both "permeability tests" and "carbonation acceleration tests" with just one coat. *Please download the PDF for the product catalog and comparison materials for impregnation agents.*
