Application steps

SUBSTRATE PREPARATION

Surfaces of cracks, joints and voids need to be clean, free of loose particles, dust, oil and any other bond-breaking substances. Any dirt must be blown out with compressed air (ensure oiler is turned off).

MIXING

SikaInject®-201 DE is supplied in containers according to the required mixing ratio of 1:1 parts by volume (partial quantities can be measured into seperate vessels).

   

Empty parts A and B into a dry clean mixing vessel and stir slowly (max. 250 rpm) and thoroughly for ~ two (2) min until homogeneous consistency is achieved. When using accelerator SikaInject® AC 20, measure the required quantity and pre-mix into part A of the base resin. After mixing pour the material into the pumps feed container (hopper) and use within potlife.

  

Note: If 2-component pumps are used the product can be pumped directly from the containers and will be mixed in a static mixer.

 

CLEAN UP

Use SikaInject® Cleaner C1 or any other solvent recommended by the injection pump supplier for cleaning the pump and tools when the resin is not cured. Only remove cured resin mechanically.
