A top-class function for suppressing the intrusion of degradation factors as a reactive silicate-based surface impregnation material with a newly established specialized focus.
L-OSMO Reaction Type XP" is a reactive sodium silicate-based surface impregnation material that contributes to the preventive maintenance and longevity of newly constructed concrete structures. With an appropriate component formulation and a rich amount of dry solids, it achieves excellent modification effects. It densifies the concrete surface and closes cracks of 0.2mm or less, thereby suppressing the progression of deterioration and reducing lifecycle costs. It has reactivity with calcium hydroxide, allowing for long-term modification effects. There are no changes in appearance after application, and any deformation of the concrete can be visually confirmed. Reapplication is easy, and it can be used in conjunction with other methods. Preventive maintenance and longevity measures can be achieved on a low budget. No special qualifications are required, and the application is quick and easy. It is also effective in areas with low applicability of silane-based surface impregnation materials, such as water accumulation points and cracked areas. *Due to the increase in product lineup in 2023, the name has been changed from "OSMO-XP" to "L-OSMO Reaction Type XP.

Company information
Rinac OSMO Co., Ltd. is a leading company that has developed a solidified lithium silicate-based concrete surface impregnation agent, L-OSMO Solidified Type KK, which has been confirmed to be effective with neutralized concrete for the first time in Japan (Patent No. 4484872). L-OSMO Solidified Type KK is also a pioneer in the field of concrete modification materials. As the importance of infrastructure maintenance increases, we have developed a solidified silicate surface impregnation agent that can be combined with various surface protection materials (Patent No. 7311215). The unique feature of densifying and modifying the concrete surface layer (a few millimeters from the surface) extends the lifespan of concrete structures.
