Non-removable threadlockers are adhesives designed to fill the gaps between threaded surfaces. By occupying these spaces, they generate sufficient friction between the threads to prevent loosening and ensure secure locking. Different models of non-removable threadlockers feature distinct chemical compositions and properties, allowing users to select the appropriate product based on specific application scenarios and requirements.
LOCTITE 270 is a high-strength non-removable threadlocker, suitable for large threaded connections with diameters ranging from 3/8 inch to 1 inch. It boasts extremely high strength, vibration resistance, heat resistance, and corrosion resistance, making it ideal for high-strength applications such as heavy machinery and automotive industries.
LOCTITE 263 is a medium-strength non-removable threadlocker, applicable to threaded connections with diameters not exceeding 3/4 inch. It offers high strength, vibration resistance, and corrosion resistance, and is widely used for thread fastening in mechanical equipment such as automobiles, motorcycles, and bicycles.
PERMABOND A131 is a high-strength non-removable threadlocker, designed for threaded connections with diameters between 1/4 inch and 3/4 inch. It exhibits extremely high strength, vibration resistance, heat resistance, and corrosion resistance, making it suitable for high-strength scenarios including heavy machinery and automotive applications.
When using non-removable threadlockers, the following points should be noted:
-
Cleaning: Before applying the adhesive, thoroughly clean the surfaces of the threads and connecting parts to ensure the adhesive can fully fill the gaps.
-
Dosage: Apply an appropriate amount of adhesive according to the size and model of the threaded connection. Excessive application not only wastes costs but may also affect the service life of the threaded components.
-
Curing: The adhesive requires a certain amount of time to cure. It is recommended to allow sufficient curing time before putting the assembly into use to ensure optimal bonding performance.
This article provides a brief introduction to several common models of non-removable threadlockers and their applicable scenarios, along with key precautions. It is hoped that this information will help readers select suitable non-removable threadlocker products, ensuring the safe and reliable operation of threaded connections.
