8. Operation Process

Check Crack → Treat with Crack → Embed Nozzle → Seal Crack → Sealing Check → Prepare Crack Pouring Adhesive → Perfuse glue → Conserve → Test

 

9. Attentions

1) Air temperature influences curing effect. High air temperature promotes curing rate, and low air temperature slows down curing rate.

2) Direct contact with A and B components has mild irritation to the skin.

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

 

10. Storage and Transportation

1) Store in a dry and clean storehouse at ambient temperature 5 °C ~ 25 °C.

2) Should not pile up in open air or rain, should not damage the package.

3) Component A and B should be kept separate to avoid mixing.

4) Effective storage period is 12 months from the date of production.

5) This product belongs to non-dangerous goods, and can transport as general chemical building materials.

6) The package should not be damaged, exposed, rained, tilted or inverted in transportation.
