| Product Name | CarboCrackSeal R is a slow-reacting, highly elastic, two-component polyurethane resin designed for injection applications. |
| Applications | ► Extended sealing and grouting of cracks and voids in buildings and other concrete civil engineering structures ► Suitable for use in tunnel linings, parking decks, concrete foundations, and dam diaphragms ► Injection waterproofing through hoses installed within concrete structures |
| Component Description | CarboCrackSeal R Component A – Polyester polyols and additives. CarboCrackSeal R Component B – Modified isocyanate. |
| Key Advantages | ► Low-viscosity resin ► Maintains its elasticity throughout its entire service life after curing ► Excellent adhesion to both dry and damp surfaces ► Good tear resistance ► Low glass transition temperature, allowing it to withstand low-temperature conditions without becoming brittle or being damaged by crack expansion caused by temperature fluctuations |
| Operating Principle | When injecting the resin using a two-component pump, the resin components are supplied separately in a 1:1 volume ratio and mixed immediately before entering the packer by means of a static mixer installed in the injection line. The resin mixture is injected into the crack or void being sealed until the resin begins to emerge from the control outlets. |
| Packaging | CarboCrackSeal R Component A – 20 kg plastic canister. CarboCrackSeal R Component B – 22 kg plastic canister. |
| Storage | Shelf life: At least 12 months from the date of manufacture when stored in a dry place at temperatures between 10°C and 30°C. |
| Recommendations | The polymerization reaction can be accelerated by adding an accelerator. |
| Equipment | Compact single-component or two-component injection pumps with manual, pneumatic, or electric drive, along with injection accessories such as packers/sealing packers and embedded injection hoses. |
