Application

  • Cartridge: Open the easy-open cover at the back, pierce the film at the mouth of the tube, screw on the matching glue nozzle, and load the glue into the hard packaging glue gun;
  • Sausage: Put the glue into the soft packaging glue gun and cut off the sealing mouth, attach the matching glue nozzle, and tighten the gun cover;
  • Barrel packaging: depends on the glue extrusion pump and glue coating equipment;
  • According to the construction requirements, the glue nozzle is cut into triangles or circles, and glue can be applied in spots or strips. It must be installed and positioned within the glue surface drying time.

Features

  • Excellent bonding performance
  • Excellent extrudability and thixotropy, non-sag.
