Sika® Injection-307

Polyacrylic elastic injection resin for permanent watertight sealing

Sika® Injection-307 is a polyacrylic,3-part elastic based injection resin with a very low viscosity and adjustable reaction time

  • Provides a passivating environment for embedded steel reinforcement
  • Adjustable curing time between 10 and 50 minutes
  • Permanently elastic, can absorb limited movements
  • Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
  • Very low viscosity comparable to water
  • Cured Sika® Injection-307 is insoluble in water and hydrocarbons and resistant to alkalis.

* reaction at cold temperatures – more accelerator (A1) is required than is supplied in the kit.

The quantity in Table 1 of accelerator (A1) per 9.6 kg of resin (A), will yield ~20 litres of mixed resin. The total Accelerator solution must always be 1000 ml (refer to example below).

Example

Ambient temperature: +22 °C (+72 °F)
Required reaction time: 30 min.

Accelerator = 290 ml
Water = 710 ml
Total volume = 1000 ml
 
Note:

1) When using one component pumps: Workability time (pot life) = Factor 0.8 x Reaction time (refer to metering chart)
2) The given data are laboratory parameters and may deviate depending on the situation and conditions on site. Reaction time measured in 100ml specimen.

Application steps

MIXING

Mixing Sequence

1. Hardener solution

Pour 10 litres of water in a clean container. Dissolve the content of 2 bags (total 800 g) of Part B in the water. Stir with a mixer at low speed the hardener solution thoroughly until Part B is completely dissolved.

 

2. Accelerator solution

Determine the required quantity of accelerator (A1) from the accelerator metering chart (Table 1). Dilute the selected quantity of accelerator with water to a total quantity of 1 litre accelerator solution.

3. Accelerator Solution with Part A resin

Pour the 1 litre of accelerator solution into 1 x 9.6 kg container of Part A and shake/mix thoroughly.

 

4. Resin solution with hardener solution

Depending on the type of injection pump used activate the injection resin using one of the methods below:

  • One component pump: Pour a partial amount of the final pre-mixed solution in the ratio of 1:1 by volume into a clean mixing container. Mix thoroughly and pour into the storage container of the pump.
  • Two component pump: Pour the resin solution into the storage container of the pumps ‘A’ side. Pour the Hardener Solution into the storage container of the pumps ‘B’ side. Then pump at a ratio of 1:1 by volume.

CLEANING OF TOOLS

Clean all tools and application equipment in accordance with the Product Data Sheet for the ‘Sika® Injection Cleaning System’.
