barrier layer

A barrier layer refers to the micropore-free layer on the surface of a substrate. Your main goal? Prevent water vapor from reaching the substrate surface. This may sound simple, but the implications and applications are far-reaching and of great importance across many industries.

Why is a barrier layer so important?

Moisture can be problematic for many materials. It can affect the structure, integrity and function of a material. Therefore, it is often necessary to create a barrier that prevents water vapor from coming into contact with the material. This is where the barrier layer comes into play.

In industries such as electronics, packaging and pharmaceuticals, the barrier layer is invaluable. It ensures that products last longer, retain their quality and are protected from external influences.

How does a barrier layer work?

The barrier layer works by forming a dense, micropore-free layer. Since it has no pores, water vapor cannot pass through. This makes them an effective barrier against moisture.

Some barrier layers are formed through special coating techniques or by adding certain materials during the manufacturing process. Others are manufactured through physical or chemical processes.
