Spray the catalyst to one side of the crack and then apply the binder on the side.4, the scratch or crack on both sides of the original position of good, rapid compression, about 1 min, you can get good bonding effect. Finally, the bonding site shall have a 3~12 h hardening time to achieve maximum bonding strength.
1. Soak the clean cloth with a solvent that removes paraffin, grease, and silicone.
