Sika® Injection-307
Polyacrylic elastic injection resin for permanent watertight sealing
Sika® Injection-307 is a polyacrylic, 3-part acrylate 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
- Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
- Very low viscosity comparable to water
- After curing the Product is insoluble in water and hydrocarbons and resistant to alkalis
Usage
The Product is designed for:- Crack and joint injection
- Injection of SikaFuko® injection hoses to seal construction joints

MIXING
PREPARE PART B SOLUTION
- Pour 10 litres of water in a clean container.
- Add1 bag (800 g) of Part B to the water and mix thoroughly with a low speed mixer until Part B is completely dissolved.
PREPARE ACCELERATOR SOLUTION
- Determine the required quantity of accelerator (Part A1). Refer to the Accelerator metering chart in the Mixing Ratio section.
- Dilute the selected quantity of accelerator with water to a total quantity of 1 litre accelerator solution.
MIX ACCELERATOR SOLUTION INTO PART A RESIN
- Pour the 1 litre of accelerator solution into 1 × 9.6 kg container of Part A and shake to mix thoroughly.
MIX RESIN SOLUTION AND HARDENER SOLUTION
One component pump:
- At a ratio of 1:1 by volume, pour the resin solution and hardener solution into a clean mixing container.
- Mix thoroughly with a mixer and pour into the hopper of the pump.
Two component pump:
- Pour the resin solution into the hopper of the pump`s ‘A’ side.
- Pour the hardener solution into the hopper of the pump`s ‘B’ side.
- Pump the Product at a ratio of 1:1 by volume.
APPLICATION
IMPORTANT
Environmental considerations
Failure to properly assess the jobsite and the scope of the application can lead to a loss of Product performance.
- Survey the jobsite to assess foundations and ground conditions before carrying out curtain injection in close proximity to or within existing structures.
- Check to make sure there are no open pipes or drainage systems close to injection areas.
- Prior to use check the Product's gel time within the local site ambient conditions.
- Contact Sika technical services for specific information on resistance to hydrocarbons or chemicals.
Reference must be made to further documentation where applicable, such as relevant method statements, application manuals and installation or working instructions.
Sika® Injection-307 can be used with standard one or two component injection pumps.
CLEANING OF TOOLS
