 epoxy based concrete crack repair adhesive  

Product features 
HM-120ML epoxy based concrete crack repair adhesive is two-component modified epoxy resin adhesive, mainly applied to use with pouring crack adhesive together, seal fracture surface and paste pouring glue nozzle, or used for concrete surface repairing and leveling construction.

1.Belong to modified epoxy resin, high initial adhesive force.

2.Curing at room temperature, fast curing speed and can be adjusted according to users’ requirements.

3.High strength, good aging resistance and chemical resistance properties.

4.Not shrink basically when curing, good thixotropic property.

5.Very strong thixotropic property and easy Scraping.

6.Wide proportion of preparing glue, easy to control operational time.

Typical uses  

Match the use with HM-120M pouring adhesive, HM-120L pouring crack adhesive,when grouting and repairing the concrete cracks, seal fracture surface and paste grouting nozzle, in the process of pouring and pasting steel plate construction, seal the slit around, concrete surface defect repair and leveling construction.

Technical Parameters 

Operation Process

1.Clean the surface which need coat and scrape crack repair adhesive, without oil, sand or floating dust, etc. and keep dry;

2.Prepare glue according to recommended proportion, the proportion of A and B is 2:1, the operable time is about 45 to 60 minutes. With the B dosage increases, operable time is reduced accordingly. Each preparing glue quantity should not be too large to use up in the operable time.

3.Weigh crack repair adhesive to a clean and dry container according to the recommended ratio of preparing glue, use putty knife or other special tools to stir until the color exactly the same.

4.When used to the construction of crack perfusion, putty knives were used to coat and scrape back and forth along the cracks and evenly coat a layer of HM-120ML daub with thickness of 1 ~ 2 cm, width of 2 ~ 3 cm. Notice to prevent small air bubbles, sands, etc, from entering to cause leaky seal. When pasting glue injection nozzles, should notice to avoid clogging glue injection holes.

5.When used to the pouring and pasting construction of steel plate, seal the slit around the steel plates, bolts and grouting nozzles until compact after spatula was adopted to coat and scrape crack repair adhesive repeatedly.

The next process of construction can be carried out after crack repair adhesive seal construction one day (25 ℃).

 Points for Attention

Construction environment is dry and ventilated, paste surface is clean, dry and free of oil; curing ambient temperature is not less than 5 ℃; curing time can be adjusted according to the difference of specific uses;

The construction workers of this product should take necessary productive measures (such as wearing masks, gloves, goggles, safety helmet, etc), if it accidentally touched the skin or clothes, acetone can be used to wipe at once, and then a great deal of clear water is used to flush;

If accidentally swallowed or splashed into the eyes, please seek medical service at once.
