Bolt anti-loosening labeling paste provides a more intuitive and simple inspection method for loosening and tampering of bolts and nuts, with simple construction and good fastness.
It can be applied to most places with bolts (such as steam turbine, wind power blade connecting bolts, locomotive bogie and other key connecting bolts, etc.) to provide reliable torque marking scheme.
Before use,clean the surface of bolts and firmware required to be marked to ensure that there is no dust, oil, etc. Apply a continuous label between bolts and firmware until it is naturally cured. Please cover the product immediately after use to prevent the product from curing in the air and affecting the effect of next use.
Our Tamper Proof Torque Marker can be applied to most places with bolts as Torque Seal Marker(such as steam turbine, wind power blade connecting bolts, locomotive bogie and other key connecting bolts, etc.) to provide reliable torque marking scheme.
With the function of cross-check,it has good properties of Viscous coating gummy, slow drying, toluene and xylene free of low odor, easy to apply.
The curing time depends on the thickness of the coating, the dry time of the table is 30-60 minutes, and the dry time is 5-7 days.
