Rapidstick™ 8-7400 Tamper Evident Ink/Varnish Seal

Rapidstick™ 8-7400 Tamper Evident Ink/Varnish Seal is a red, solvent-based marking seal for electronic tuneable items, factory fixed components, screws, nuts, and other applications where evidence of unauthorised tampering or access is visibly required. It is water and moisture resistant and offers excellent flexibility.

8-7400 is ideal for tamper-proofing rotary controls to ensure that pre-set or tested parameters do not move under vibration or accidental drop. Typically, 8-7400 is used for marking potentiometers, tuneable filters, tuneable microwave devices, electronically tuneable ferroelectric devices, and RF tuneable devices.
