Our tamper proof sealants are designed to perform in challenging environments where reliability is critical.

These sealants provide a clear visual indication if a fastener or component has been tampered with, making them ideal for inspections and quality assurance. For a dependable, quick-drying option, the 3M Scotch-Weld EC-1252 Tamper Proof Sealant is a popular choice that leaves a durable mark and stands up to heat, fuel and fluid exposure. It’s used across aviation, defense and electronics settings where accuracy matters and there’s no room for questions.

Tamper proof materials work with sealant systems, not in place of them. Whether you're applying an airplane sealant, aviation sealant or aircraft sealer, these markings provide visual confidence that components haven’t been compromised after final assembly. They're often used alongside an aircraft sealant during maintenance checks or post-inspection procedures. Like other sealants for aircraft, they have a thixotropic nature that allows them to be applied to vertical or horizontal surfaces.
