GELACRYL TI
3-component poly-acrylate gel for tube injections
Product Description
GELACRYL TI is a special 3-component poly-acrylate injection resin developed specifically for injection of preventative injection tubes. The viscosity does not increase momentarily as with other Gelacryl resins but builds up in linear fashion to allow optimal control of the re-injection process. GELACRYL TI has excellent adherence to the surface and has a post-expansion of up to 350% of the original volume in contact with water.
Field of Application
Injection and re-injection of preventative injection tubes.
Product Advantages
- Easy to use 3-component system
- Long gel time allows controlled injections
- Linear viscosity increase allows re-injection process to be monitored
- Post-expansion up to 350% in contact with water
Application
1. Resin preparation
- Add the complete contents of Component A2 (small plastic bottle) to Component A1 (large plastic jerry can). Mix thoroughly.
- Prepare the B-component by filling a container with the same quantity of water as the mixed A-component (9.45 ltr). Add Component B1 to the water and mix for 3 minutes.
- The prepared components are pumped with a 1:1 ratio injection pump IP 2C-Gel.
2. Injection
- Connect the pump to the entrance port of the injection tube.
- Fill the tube with resin, when resin comes out of the exit port, this port is closed with a conical packer or wedge.
- Start injection by slightly increasing the pressure until the resin starts to flow.
- When the resin is expelled from the joint, stop the injection and allow the resin to react for 3-5 minutes.
- After waiting 3-5 minutes, the viscosity will have sufficiently increased to prevent flow of the material. The tube is now injected with fresh material to push the reacted material into the joint and fill all cavities.

3. Re-injection
- When re-injection is required, the tube needs to be flushed under low pressure with water. This needs to be done within the gel time of the resin.
