Lithium nitrite-based rust prevention impregnation material 'KT-N'

Lithium nitrite-based rust prevention impregnation material 'KT-N'

Alkali aggregate reaction measures and longevity! Suppressing rebar corrosion in concrete structures.

"KT-N" is a lithium nitrite-based rust prevention impregnation material. Nitrite ions have the effect of regenerating the passive film on the surface of rebar, while lithium ions help suppress the expansion of alkaline silica gel. By supplying this product through injection methods, cross-section repair methods, and impregnation methods, the passive film around the rebar is regenerated, and it is expected to continue to suppress the corrosion of the rebar. Additionally, by impregnating the silicate-based impregnation material "KC Guard α" after the injection and impregnation of this product, the measures for extending the lifespan of concrete structures will be further ensured. 【Features】 ■ Regeneration and protection of rebar passive film ■ Suppression of macrocell corrosion occurrence ■ Alkaline addition ■ Suppression of rebar corrosion in concrete structures (ASR measures) ■ Improvement of durability of concrete structures, prevention of aging, and extension of lifespan *For more details, please refer to the PDF materials or feel free to contact us.

Deep Insilan, a silane-based impregnation material.

Deep Insilan, a silane-based impregnation material.

Achieves a state of high strength and extreme resistance to degradation through the bonding of silicon and oxygen (siloxane bond)!

"Deep Insilan" is a silane-siloxane based impregnation material that forms a high-density water-repellent layer by penetrating the concrete surface, effectively preventing the long-term intrusion of external deterioration factors through high water repellency. The water-repellent layer blocks moisture and chloride ions from the outside, while allowing water vapor from within the concrete to pass through. Additionally, this product causes minimal surface changes after application, maintaining the texture of the material over a long period. Please feel free to contact us if you have any inquiries. 【Benefits】 ■ Extended lifespan ■ Suppression of deterioration progression ■ Surface protection ■ Increased durability ■ Prevention of deterioration factor intrusion, etc. *For more details, please download the PDF or contact us.
