Koester - Injektionsgel G4 three-component acrylic gel

Acrylic, water-based three-component gel with low viscosity, retaining elasticity after curing.

Properties

• material approved for contact with drinking water
• can bind water during the reaction
• after setting, it has a swelling capacity of up to 10% by weight
• in a dry environment it can dry out and reduce its volume; after contact with water, it returns to its original volume
• due to its low viscosity, the product can be injected into materials with small pores

Application

• sealing of external walls in contact with the ground by means of curtain injection (injection into the ground)
• surface injection of highly porous or scratched elements in a building
• making horizontal diaphragms in walls using the pressure injection technique
• sealing the channel in, voids, tunnels, joints in concrete and masonry elements

Technical data

• solubility - miscible with water
• viscosity 4 mPa s / + 20 ° C
• water resistance 7 bar
• application temperature> +5 ° C
• reaction time start of viscosity increase 4 min / + 20 ° C
• gel time 6 min / + 20 ° C
• final hardening 15 minutes / + 20 ° C
