Screw Precoated Sealant 2200 Series


LETBOND®The screw pre-coated anti-loosening sealant is a special thread locking sealant, which is pre-coated on the thread surface and dried to form a layer of adhesive film with certain adhesion. When the assembly is screwed, the glue mold and microcapsules are crushed to release the initiator and glue solution, which promotes the polymerization of anaerobic glue monomer and fills the whole gap of the thread bite part. A thermosetting plastic with certain strength and toughness is formed, which can reliably lock and seal the thread engagement part, and the performance after curing is the same as that of liquid anaerobic adhesive. Since there is no on-site dripping, the problems of missing coating, less coating, flowing and affecting the production rhythm are avoided. Therefore, it is particularly suitable for mass production assembly line use.
