Product description:

Modified epoxy resin with low viscosity and double liquid grouting material type, cold setting type injection repairing epoxy resin for special purpose, it is mainly used for repairing concrete structure crack empty drum, low heat, low shrinkage after hardening, for a variety of structures with very superior to focus on, especially for concrete better then. Through mechanical perfusion (high pressure) or syringe injection method (low pressure), can be further structure is extremely tiny cracks, sufficient to achieve the effect of repair and reinforcement, to restore structure their integrity, and achieve the purpose of the integration.

Performance indicators:

Storage stability:

Please do not placed in the high temperature or sun exposure, best in shade. Under normal circumstances, at least a year.

Method:

High pressure or low pressure injection.

High pressure infusion:

1, the deployment of epoxy, curing agent B, mixing ratio A: B = 1:1 (weight ratio), no need to add any additives or thinner.

2, to make the crack filling completely, should fill in 30 minutes for the second note, when slurry leaking from cracks in the stop.

3, 72 hours after cleaning has solidified epoxy slurry on the lining, pull out the water needle, with polymer waterproof mortar closed hollow.

Low-pressure perfusion:

1, take groove along the fissures, groove width 10 to 15 cm, thickness of groove depth according to the basic situation decision. With air pump or blower dust in addition to the groove.

2, mixing epoxy putty glue, the place closed paste grouting base and fracture surface, but cracks may not be blocked.

3, the mixing ratio of A/B in accordance with the epoxy resin mix within inhaled syringes after installed to the injection of the base, pull out the plug after tightening the grouting.

4, check the residual amount of grout in the infusion needle tube. If there is no residual should immediately added epoxy resin. Repeat the steps until the syringes have residual, says it has filled. Remove the needle cylinder, quickly install plug in the base.

5, after waiting for internal crack epoxy hardening, can knock out base, clean up the lining surface.

Note:

1, during the period of construction, should avoid contact with skin, must wear gloves, goggles, please rinse with water immediately of any contamination, eyes accidentally touch this product should be hospitalized immediately.

2, the main agent and curing agent must be in accordance with the proportion can stir well before use.

3 mixes, the main agent and curing agent, should be used within the time available to complete, in order to avoid material curing can't use.

4, after use, machinery equipment, scaling, mixer and containers, etc., shall be washed with acetone thoroughly prior to hardening.
