The main purpose of screws is to hold together and bond the mating surfaces. However, over time, the threads of the screws can loosen, and wear out due to weight and force. By using thread-locking adhesives, we can prevent the loosening of the screw joints. This material contributes to ensuring that the screw does not come off due to vibration or impact. Let's see what you need to know about threadlockers!
A threadlocker is a liquid substance that fills the gaps in the screw threads, ensuring that the screw cannot loosen due to movement, vibration, or wear and that the bond remains intact. The application of this one-component adhesive is simple, without creating mess or contamination, and its effect is long-lasting. Due to these properties, it is widely used in various industries.
The bonding time for the adhesive ranges from 20 to 60 minutes, depending on the characteristics of the surfaces, but it may take 12 to 24 hours to reach full strength.
Threadlockers have numerous advantages that make their use worthwhile. Here are the most important ones:
Adhesives of this type can be used in various industries wherever screw reinforcement is needed. Typical examples include automotive manufacturing where resonance caused by the engine or engine block can loosen screws holding the vehicle's components, such as those in the suspension system. The adhesive prevents the screws securing vehicle parts from loosening, preventing them from falling off and causing damage to other parts of the car. Noisy and moving components can cause wear, exposing the car to unexpected malfunctions.
For over two decades, Flanker has been providing comprehensive solutions for industrial players. Our product range includes structural adhesives, including threadlockers and screw-locking adhesives such as 3MTM Scotch-WeldTM TL70 Threadlocker, which is a one-component, high-strength adhesive that ensures a durable bond. A classic threadlocker is the medium-strength 3MTM Scotch-WeldTM TL42, which allows fasteners to withstand vibrations, impacts, and corrosion. Another variation is the 3MTM Scotch-WeldTM TL62, which provides rapid curing. Take a look at the Flanker website!
