Product detailed description

Loctite 221 is an excellent low-strength adhesive that is used to secure and seal nuts or bolts with long threads, the suitable material is copper. The adhesive is designed for applications where low strength and easy disassembly without damage to the threaded joint are required. Loctite 221 locking adhesive has the ability to harden without air access in the joint between bonded metal surfaces and at the same time prevents loosening or leakage of the joint, which is caused by vibrations and shocks:
· possibility of loosening the joint,· sealing joints between metals,
