2218 Wear-resistant Repairing Agent Is a two-component epoxy adhesive to metal titanium compound and hard ceramic aggregate wear-resistant composite materials.
Performance Feature
Black paste, room temperature curing, high bonding strength with matrix; After repair coating wear resistance is medium carbon steel surface quenching 2 ~ 8 times.
Typical Applications
Used for coarse grinding grain is less than 25 mm in diameter of abrasive wear parts repair, protective coating can be done. Apply to repair or preliminary protection propeller pump, slurry mixer, such as slag transporting pipe bending, etc.

Instructions
1. Cleaning and preparation: polished surface of unattended, bared metal body and make it rough. Clear oil, it is recommended to use detergent 7755 cleaning, have seen better.
2. Glue: according to the dosage, by weight than 4:1 says in part A and part B, mixing evenly, make it A uniform color.
3. Paint Glue: the glue on the mend, compaction force, eliminate sub in the cracks, porosity, shape, smooth.
4. Cure:At 1 day can be cured, if you want to faster curing, can be appropriately heating, curing in 80 ℃ for 2 ~ 3 hours.
5. The reaction is exothermic reaction, with glue should be paid attention to.
1) The more amount of glue, the faster the curing reaction.
2) The higher the temperature, the faster the curing reaction.
3) To achieve the best performance, must be in strict accordance with the provisions of proportion.
4) Environmental temperature under 10 ℃ when, can preheat the repaired surface.
5) Completely curing rear can achieve the best physical and mechanical properties.
6. Shorten curing time method:
1) Improve the environmental temperature.
2) Improve the unattended workpiece temperature.
3) Coating after repairing adhesive with infrared lamp, halogen lamp, such as the heat source heating, but the outside heat source should be 400 mm from repair layer (ambient temperature is not higher than 100 ℃), not directly with flame heating.
Notes
1.Not finished part A and B respectively sealed preservation, so that next time, each in A and B components that not use up seal save, in order to use next time.
2.Contaminated adhesive solution can no longer be in the original tins, lest affect the jar residual adhesive solution performance.
3.Keep away from Children.
4.Can irritate the eye skin, should be used in a well ventilated place.
5.If touch with eyes and skin, immediately after wiping, rinse with water.
The safety of the product information, please refer to the product MSDS.
