The "RCG Inner Seal α Method" is a construction technique that visualizes the application area and makes it easy to confirm the scope of work by combining a non-toxic and safe fading colorant. This color fades to colorless and transparent within a few days due to sunlight. Additionally, of course, it primarily consists of particle colloids (sodium silicate and potassium silicate) and forms a dense layer with "C-S-H gel," a reaction product with calcium hydroxide, which suppresses the intrusion of deterioration factors such as carbon dioxide, chloride ions, and water into the concrete. Its excellent performance as a silicate-based surface impregnation material remains unchanged. 【Features】 ■ The use of colorants allows for visual confirmation of the application status and range. ■ After construction confirmation, it fades within a few days due to sunlight, returning to the original color of the concrete. ■ Usable for both new and existing constructions. *For more details, please download the PDF or feel free to contact us.
