"Protect Coat" is a coating material that enhances acid resistance, chemical resistance, crack sealing ability, resistance to neutralization, resistance to UV degradation, and heat resistance. It prevents water, chlorides, and other deterioration factors from penetrating into porous materials such as concrete. Additionally, its water-repellent and oil-repellent properties improve graffiti resistance and surface cleanliness. 【Features】 - Prevents the penetration of deterioration factors such as water and chlorides - Particularly excellent in salt damage resistance - Protects against the intrusion of water and chloride ions from penetrating cracks - Prevents rusting of internal rebar - Improves graffiti resistance and surface cleanliness through water-repellent and oil-repellent properties *For more details, please refer to the PDF document or feel free to contact us.

"Dry Protect" is a lithium silicate-based silane composite surface impregnation water-repellent material that enhances the water resistance by imparting water-repellent properties to "Inner Protect," while also strengthening the ability to block fine cracks and prevent water infiltration from cracks. Even in environments where water pressure is applied to the coated concrete, it prevents the intrusion of deterioration factors such as water and chlorides. Additionally, it excels in salt damage resistance, protecting against the intrusion of chloride ions and preventing rusting of internal rebar. 【Features】 ■ Enhanced water resistance that prevents the blockage of fine cracks and water infiltration from cracks ■ A hybrid product that also possesses the deterioration suppression performance of "Inner Protect" ■ Excellent salt damage resistance ■ Protects against the intrusion of chloride ions ■ Does not absorb water and swell with insoluble gel *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Inner Protect Series," a lithium silicate-based modifier handled by Japan Road Maintenance. By using this product, it is possible to reduce the initial cracks that occur in newly poured concrete and improve its strength. Additionally, for existing concrete, it seals the cracks internally, suppressing the intrusion of water and chlorides, thereby restoring strength. 【Features】 ■ Realization of 100-year durable concrete ■ Easy application ■ Harmless to humans ■ No environmental impact ■ Reduces and seals concrete cracks, shielding against deterioration factors *For more details, please refer to the PDF materials or feel free to contact us.

Introducing "Inner Protect / Inner Protect CC / Prosiman." "Inner Protect" and "Inner Protect CC" are lithium silicate-based concrete surface impregnation materials and curing agents that can suppress the occurrence of initial cracks. Additionally, "Prosiman" is a silicate-based modifier and reinforcing agent that replenishes the calcium components lacking in concrete and restores the alkalinity of the surface. The effectiveness is doubled when used in conjunction with the above two products. 【Features】 <Inner Protect / Inner Protect CC> ■ Penetration of 20 to 40 millimeters ■ Suppression of initial crack occurrence ■ Improvement of surface strength ■ Suppression of deterioration from salt damage, freeze-thaw cycles, etc., leading to increased longevity *For more details, please refer to the PDF materials or feel free to contact us.

"Romen" is an oil-absorbing material that quickly adsorbs oil and unpleasant odors from the surface just by scattering it. It firmly adsorbs even on frozen surfaces and in bad weather, without deformation or discoloration due to ultraviolet rays or heat, and without oxidation from ozone. Additionally, since the main component is made of natural minerals, it is a product that is gentle on both people and the environment. 【Features】 ■ Adsorbs oil that has seeped into the surface ■ Adsorbs ammonia odors ■ Usable on frozen surfaces ■ Continues to adsorb oil and unpleasant odors even in bad weather ■ Powdered material made from natural minerals *For more details, please refer to the catalog or feel free to contact us.
