| Application |
Thread locking |
2. Typical use:
DX272 is recommended for permanent locking and sealing of threads below M36. High temperature resistance, with a maximum temperature of 230 ℃. Can be used for locking double headed threads on cylinder heads. After the air between the threads is isolated, the curing process begins immediately. Can prevent loosening and leakage caused by impact and vibration.

5. Usage:
Assembly:
1、 For optimal results, thoroughly clean the inner and outer surfaces of the threads with DX755 cleaning agent and air dry.
2、 If the material is an inert metal, spray the accelerator DX7649 on the mating surface and let it dry.
3、 Shake well before use.
4、 To prevent glue from blocking the glue nozzle, avoid the nozzle from coming into contact with metal substances.
5、 Apply sufficient adhesive to the mating area of the threads, and do not apply it to the first section of the threads. The adhesive width should be 3-5 threads. For larger threads and clearances, the amount of glue applied can be adjusted and the product can also be applied to the internal threads.
6、 Tighten the threads using regular methods until they are in the correct position. Reached maximum intensity after 24 hours.
disassemble:
1、 Use standard disassembly tools to disassemble.
2、 In rare cases, due to the long fitting length, it is impossible to disassemble at room temperature. The bolts and nuts can be locally heated to 232 ℃ and disassembled while they are still hot.
clean:
For solidified glue, it can be soaked in gasket remover DX790 or mechanically polished with tools such as steel brushes.
6. Storage conditions:
1、 This product should be stored in a dry and cool place, with an ideal storage temperature of 18-26 ℃.
2、 To avoid contaminating unused adhesive, do not pour the poured adhesive back into the original packaging container.
3、 Keep away from children.
