We would like to introduce the test results of "Inner Coat" from RCG Japan Co., Ltd. In the "Water Permeability Test" conducted at the Building Materials Testing Center, the suppression of water infiltration (waterproofing) was measured. By applying the Inner Coat, a reactive gel is formed, reducing the pore diameter, which prevents water permeability into the interior and demonstrates waterproofing effectiveness. Additionally, tests were conducted to verify the suppression of initial drying shrinkage cracks, salt damage, and freeze-thaw effects. 【Conducted Tests】 ■ Water Permeability Test ■ Average Chloride Ion Penetration Depth Test ■ Freeze-Thaw Test ■ Accelerated Carbonation Test ■ Friction Test *For more details, please refer to the external link page or feel free to contact us.

• Concrete wall

Tile walls are widely used as exterior wall materials in many buildings. However, due to long-term pollution, acid rain, and other factors, the deterioration of tile joints, efflorescence, and surface dirt can progress. Stubborn oil and exhaust gas stains that adhere to the surface require special cleaning, which can be costly. In particular, the deterioration of joints can lead to water infiltration, causing tile detachment and leaks. "HB Seal" simultaneously suppresses water absorption and contamination, forming a waterproof and protective layer suitable for maintaining aesthetics. 【Mechanism】 ■ During application: Water-repellent effect ■ After application: Water-repellent properties change to hydrophilic over several months to years (varies with UV exposure and environment) 　⇒ Changes to hydrophilic, demonstrating anti-soiling effects. We are looking for distributors for "HB Seal." Please feel free to contact us for more details. *For more information, please refer to the PDF materials or feel free to contact us.

• Coating film waterproofing material/permeable waterproofing material

We would like to introduce the mechanism of "HB Seal." HB Seal is a mixed solution of ultra-fine particles and silicone (water-repellent agent). It changes from water-repellent to hydrophilic over a period of several months to a few years after application. 【Mechanism】 ■ Apply HB Seal ■ Forms a film from the surface to the interior and penetrates ■ When the surface is exposed to sunlight, the organic components (water-repellent components) in the film formed on the surface decompose, becoming hydrophilic ■ The agent that has penetrated into the interior is not exposed to sunlight and maintains waterproof performance without decomposition ■ The inorganic film remaining on the surface also has the ability to decompose organic substances, suppressing dirt and the growth of mold and bacteria ■ Inside the joints, ultra-fine particles and C-S-H gel are generated ■ Exhibits waterproof and dirt-repellent effects that do not allow moisture and degrading factors to pass through We are looking for distributors for "HB Seal." Please feel free to contact us for more details. *For more information, please refer to the PDF document or feel free to contact us.

• Concrete wall

The main causes of "concrete deterioration" are the presence of capillaries (porous bodies) and the existence of pore solutions. Deterioration factors such as moisture, carbon dioxide, and chloride ions in the atmosphere infiltrate through capillaries and, using pore solutions as a medium, undergo chemical reactions and diffusion. It is important to densify the capillaries and reduce the pore solutions. In particular, pores larger than 50 nm (macro-pores) are said to be problematic as they allow for easier infiltration of deterioration factors. By applying our "Inner Coat" and "RCG Inner Silica," we can transform these macro-pores into harmless pores, thereby suppressing the infiltration of deterioration factors. *For more details, please refer to the external link page or feel free to contact us.
