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.
