Instructions for using Loctite 241 glue
Surface preparation
Before using Loctite adhesive, both surfaces need to be cleaned with a specialized solvent and dried immediately afterwards. This helps remove dirt, grease, and increases adhesion. If the adhesion speed is slow, you can use a catalyst such as Loctite 7649 or Loctite 7471T to increase the effectiveness.
How to apply glue properly
- For threaded holes: Apply a few drops of glue directly onto the threads in the hole.
- For threaded holes with bottoms: Apply glue 1/3 of the way down the hole, concentrating near the bottom.
- For sealing joints: Apply adhesive around the joint to ensure a tight seal and prevent leakage. Then assemble the parts according to specifications.
Note when disassembling
If parts secured with Loctite need to be removed, heat the joint to facilitate separation.
Things to avoid
- Do not use the adhesive in environments rich in pure oxygen or strong oxidizing materials such as chlorine. This may be dangerous or reduce the effectiveness of the adhesive.
- Avoid use in welds connecting highly reactive materials.
Following the above steps correctly will not only help Loctite glue achieve optimal adhesion but also ensure safety when used in all environments.
Notes when preserving Loctite 241 glue product
To maintain the quality and effectiveness of Loctite 241 glue, you need to store the product in a suitable environment. Avoid exposing the glue to direct sunlight, as this can change the internal compounds, affecting the adhesive ability when used.
After use, wipe the bottle cap clean and close it immediately. This will help prevent air from entering, which can cause deterioration of the adhesive. Proper storage will not only prolong the life of Loctite 241, but also ensure maximum performance in your applications.
