Directions for use
For Assembly
1. For best results, please clean all surfaces(external and internal) with a cleaning solvent JH755 and allow to dry.
2. If the material is an inactive metal or the cure speed is too slow, spray all threads with a activator JH7649 and allow to dry.
3. Shake the product thoroughly before use.
4. To prevent the product from clogging the nozzle,do not allow the tip to touch metal surface during application.
5. For the Thru Holes, apply several drops of the product onto the bolt at the nut engagement area.
6. For the Blind Holes, apply several drops of the products down the internal threads to the bottom of the hole.
7. For Sealing Applications, apply a 360 bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thoroughly fill the voids. For the materials into the threads to thoroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360 bead of product on the female threads also.
8. Apply enough adhesives to the mesh of thread,except the first thread, the width is about 3-5 threads. To some large threads and gap , can increase the quantity of adhesives and apply it to the inner threads.
9. Assemble and tighten as required. Using general method to tight the screw until its proper position
