  Jgn806 modified epoxy resin repair adhesive I
product features
Jgn806 epoxy resin repair adhesive (structural reinforcement and leveling adhesive) is a two-component modified epoxy resin adhesive with the characteristics of:
1
Good workability, easy to apply and scrape;
2
The initial viscosity is high and does not flow;
3
High self strength and concrete bonding strength;
4, aging resistance and good corrosion resistance

5
Close to the color of concrete;
6
Normal temperature curing, fast curing speed, and can be adjusted according to user requirements;
7
It does not contain volatile solvents and basically does not shrink when hardening;
8
It can be bonded on wet surface, and the bonding force is stronger in dry environment;
9
A, B with a wide proportion of glue, easy to use, non-toxic

2、 Scope of application
Repair of surface defects and pits of high-strength concrete; Leveling construction of concrete bonding surface in carbon fiber reinforcement or steel bonding reinforcement; Anti corrosion construction of concrete surfaces such as bridges (anti carbonization, waterproof and anti-corrosion); Concrete surface decoration and protection; The cracks on the concrete surface shall be closed

 
Good scratchability and sagging resistance , Defect repair and surface protection
3、 Performance index
 
4、 Construction method
1
Weigh components a and B in a clean and dry container according to the recommended mixing proportion, and stir until the color is uniform
When the amount of glue is small each time, the putty knife can be used to mix manually on the board, glass and other flat plates; When the amount of glue is large each time, it is recommended to use mixing machinery for mixing, and ensure that the edge and bottom of the container are completely mixed evenly

2
The amount of glue should not be too large each time, which is subject to complete mixing and use up within the operable time
With the increase of temperature and glue dosage, the operable time will be shortened accordingly

3
Epoxy resin repair adhesive can be used in wet epoxy construction, but its bonding performance is better in dry environment
The water film on the concrete surface shall be removed before construction, and the bonding surface shall be dry as far as possible

4
When epoxy resin repair adhesive is used for concrete surface protection (anti carbonization, anti-corrosion, etc
), polish and remove laitance, sand particles and looseness on the concrete surface before construction until coarse aggregate is exposed on the bonding surface; At the same time, ensure that the concrete surface is clean and free of dirt and impurities such as oil and dust, and evenly apply and scrape it back and forth with an putty knife to a thickness of 2-5mm

5
When epoxy resin repair glue is used for defect repair or reinforcement leveling, the loose concrete shall be removed first, and then it shall be applied to the required thickness after surface treatment according to the above method
Adding a small amount of prepared carbon fiber adhesive primer to the prepared one-year resin repair paste can achieve a certain dilution effect

6
When epoxy resin repair glue is used to seal the cracks on the concrete surface, it is recommended to expand the cracks with a cutting machine along the cracks before sealing

7
Epoxy resin repair glue can also be used to close the peripheral gap and paste the glue injection nozzle when pouring and pasting steel plate or crack glue injection repair

8
The curing speed of epoxy resin repair adhesive is fast, and it can exceed the strength of concrete body at 25 ℃ for 12-24h
