2) Wide mixing proportion, easy to control operational time.

3) Very strong thixotropic property, easy to scrape.

4) Cure at room temperature, fast curing speed, and can be adjusted according to the requirements of users.

5) Not shrink basically when curing.

6) High strength, good aging resistance and chemical resistance properties.

 

2. Application Range

1) Concrete surface defect repair and flattening construction, etc.

2) Match the use with HM-120M perfusion adhesive, seal the slit around in the construction of pouring and pasting of steel plate.

3) Match the use with HM-120L crack pouring adhesive, seal fracture surface and paste grouting nozzle when grouting and repairing the concrete cracks.
