*25 ℃ curing 30min to achieve the initial bonding strength, increase the curing temperature, can shorten the time to achieve the initial bonding strength, 60-80 ℃ curing 2-5min can achieve the initial bonding strength.
Directions For Use
Clean-up: Clean up the surface to be bonded, making it clean and dry, flame or plasma treated.
Glue preparation: Prepare the glue as per the ratio of A: B=0.85:1(W/W) 1:1(V/V) and mix evenly.
Gluing: Evenly apply the mixed glue on the part to be glued, and the mixed glue color is gray.
Curing: Determine the appropriate pressing temperature and time according to the actual process rhythm, otherwise bonding failure may occur.
