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.
