Directions for use
Clean-up: Clean the surface and remove rust, dust, oil, etc.
Gluing: Cut a suitable small hole in the spout of the cartridge and apply glue with a glue gun to the end face to be sealed, to form a continuous glue ring. In the case of pneumatic application, the air pressure is recommended not to exceed 0.4MPa.
Curing: Fold the two end faces and fasten them with bolts; the initial curing time is one hour, and the full curing time is 24 hours at 25°C and 50% humidity. Longer curing time is required in colder or dry conditions.
Storage: Unused adhesive should be stored after immediately tightening the cap and sealing the nozzle. When used again, if there is a small amount of crust on the seal, just remove it, and it won’t affect the normal use of the product. During storage, a small amount of crust may appear at the mouth of the tube, which can be removed for normal use and won’t affect the performance of the product.
