The Chemofast VK injection system is a fast-hardening composite mortar. The mortar consists of 2 components that are mixed in the static mixer to form a perfectly mixed composite mortar and can therefore harden.

The Chemofast VK is available in various packaging solutions. On the one hand in the 300ml tubular film cartridge. This can be processed in commercially available silicone squeezers. If larger quantities of composite mortar are required, the 420ml coaxial cartridge is also available. This must be pressed out with a 2K pressing device.

The Chemofast VK Allround mortar can be used for dowel fastenings in concrete and masonry. When used in perforated bricks, the appropriate sieve sleeve must be used. The product can also be used for subsequent reinforcement connections (rebar).
