Sealants, commonly known as threadlockers, are substances used to prevent the accidental loosening or unscrewing of threads in mechanical assemblies. These products are applied to the threads prior to assembly, where they act by filling the gaps between the threads, creating a secure, leakproof connection. Threadlockers are available in a range of viscosities and strengths, suitable for different types of applications and materials. Their use is common in many industrial sectors, including automotive, aerospace, construction and general manufacturing, where assembly reliability is essential.
