In the MEC process, a microencapsulated, highly reactive sealing and locking agent is applied to the threads of screws, bolts, or pipes. The agent does not react until the part is tightened; then the microcapsules break, and the sealing and locking agent instantly polymerizes to prevent loosening or leaking. After MEC processing, no locking agent or sealant needs to be applied to threads; the sealing and locking properties are activated in the assembly.
