Sika® Sigunit® P-1 AF
Sika® Sigunit® P-1 AF is a water-soluble, alkali free and high-performance shotcrete accelerator in powder form. When dissolved in water, it produces an alkali-free set accelerator for wet sprayed shotcrete.
- Alkali-free, avoiding additional leaching and pollution of alkalis and pollution of ground and surface water.
- When correctly used, marginal reduction of shotcrete strength.
- Reduction of rebound.
- Easier overhead spraying by improved bond of shotcrete to rock and concrete.
- Reduction of dust formation.
- Chloride-free, suitable for steel reinforced shotcrete and substrates.
- Easy to dissolve on site in time for shotcreting.
- Conversion of powder to liquid on site raises temperature to approx. 40°C (104°F); increasing accelerator effect considerably.
- Lower cost of logistics
