HOW TO USE

1. Surface treatment: clean up the impurities on the surface of the substrate to keep it in a clean and dry state; l
2. Coating and curing: Extrude and evenly coat the sealant on the surface of the cleaned parts according to the process requirements, and complete the curing within the specified time.

Note:

1. Apply a bead of GB888A to one of the prepared surfaces, then quickly cover with the other substrate be bonded and remove the excess sealant
2. Tool immediately before a skin forms
3. A plug of used material may form in the tip of a tube or cartridge during storage. This is easily removed and does not affect the remaining contents.
4. Air pressure should be maintained at 0.2~0.4MPa when using pneumatic gun.

Safety Instructions
During the construction and curing process, a good ventilated environment should be maintained. Before curing, contact with eyes should be avoided. If contact with eyes, rinse with plenty of water and seek medical attention in time.
