Sika Injection-101 RC is a two-component, water-reactive, low-viscosity polyurethane injection foam that forms a tight, flexible foam with a fine cell structure when cured. It is used for temporary sealing of cracks, gaps and voids in concrete, brick and natural stone. To obtain a permanent seal, an additional injection of Sika Injection-201 or Sika Injection-203 is required.

Features

• Sika Injection-101 RC can be injected like a one-component product
• the swelling reaction begins only after direct contact with water
• it swells up to 40 times in contact with water
• at low temperatures (<+10 C) Sika Injection-101 RC can be accelerated with Sika Injection-AC10
• the rate of reaction (foam formation) depends on the temperature of the mixed material, the water properties and the hydrodynamic conditions
