LOCTITE surfacing films for lightning strike protection

Boosting surface quality

How to benefit from the right surfacing film solution
Surfacing films are designed to improve the surface quality of honeycomb stiffened composite parts. They also provide a barrier for dissimilar materials, decrease surface preparation time and provide protection of structural fibers. But this is not all: laminated films composed of a surfacing film and a conductive metal foil protect the composite structure from damage caused by lightning strikes.

Protect your aircraft from lightning strike damage
What are the requirements for optimum lightning strike protection of aircraft composite parts? A Maximum electrical conductivity is essential. A lightweight solution is important too. And process efficiency should be maximized – including easy repair after lightning strike.

How to gain even more benefits: LOCTITE surfacing films & lightning strike protection
