RESINBAU · INJECTION SYSTEMS
A four-component acrylic system with very low viscosity. It forms a soft, flexible hydrogel for sealing, structural injection and curtain injection. Adjustable reaction time allows the injection process to suit site conditions. Water-dependent swelling and shrinkage are reversible.
The 4K system is applied using a two-component stainless-steel pump. Prepare two working mixtures (A1 + A2 and B1 + B2), which meet at a 1:1 ratio in the mixing head. Follow the technical data sheet when selecting reaction time.
