Protectosil DRY CIT
Protectosil DRY CIT is a highly efficient, water redispersible powdered corrosion protection additive designed for cementitious building materials. Using a multifunctional silane system provides long-term protection for embedded steel reinforcement, preventing chloride-induced pitting corrosion and ensuring improved durability of concrete structures. This advanced additive is ideal for both new construction and maintenance projects, especially in environments exposed to chlorides, deicing salts, and harsh marine conditions.
Key Benefits of Protectosil DRY CIT
- Part of cement-based dry mortar formulations for easy integration
- Forms an in-situ protective layer on steel reinforcement during setting
- Protects against pitting corrosion from chloride concentrations above the critical threshold
- Significantly reduces water uptake for longer-lasting structures
- Enhances mortar wetting properties during processing
- Compatible with EN 1504-3 and EN 1504-7 requirements
Common Applications
Recommended for modification of cement-based materials and repair mortars in high-exposure conditions, including:
- Maintenance of parking decks, facades, balconies, walkways, piers, bridge decks, beams, and columns
- Concrete structures exposed to deicing salts, such as tunnels, highways, and bridges
- Marine and tidal zone structures in high-chloride environments
- Concrete repair mortars by EN standards
Packaging
Supplied in 15 kg paper bags with polyethylene liners, with palletized loads of 45 bags (675 kg total). Larger bulk packaging options are available upon request. Shelf life is at least 12 months in sealed containers under dry, cool conditions.
