A mixture of ultrafine particles and silicone (water-repellent agent)! After application, the water-repellent effect gradually changes to hydrophilicity.
We would like to introduce the mechanism of the "HB Seal" handled by RCG Japan Co., Ltd. When this product is applied, it forms a film from the surface to the inside, penetrating the material. When the surface is exposed to sunlight, the organic components (water-repellent components) in the film formed on the surface decompose. As a result, it becomes hydrophilic, and the product that has penetrated inside is not exposed to sunlight, allowing it to maintain its waterproof performance without decomposition. [Mechanism] ■ Water-repellent → Becomes hydrophilic after several months to several years post-application *For more details, please download the PDF or feel free to contact us.

Company information
We modify concrete and joint cement to prevent the passage of water and deterioration factors by using our developed products, "Inner Coat" and "HB Seal." For civil engineering applications, we have developed "RCG Inner Silica" and the newly confirmed "RCG Inner Silica α." The coloring fades and loses color due to sunlight, so the aesthetics and landscape after construction do not change. Additionally, for exterior wall tiles that have deteriorated over time, we have started to handle the "Makuhari Newton Method," a technology that forms a strong transparent coating to prevent damage from falling exterior wall tiles to third parties. For waterproofing and deterioration prevention of concrete and tile finishes, please consult RCG Japan Co., Ltd. first.
