What Are the Consequences of a Damaged Door Waterproof Membrane?

[MacGriffin]

After the door waterproof membrane is damaged, the door cannot remain sealed. Below is an introduction to waterproof membranes: 1. Introduction: A waterproof membrane is a top layer with oil and water resistance properties, thin and does not alter the optical performance of the anti-reflective coating. 2. Function: After multiple layers of anti-reflective coating are applied to the lens surface, the lens becomes particularly prone to stains, which can damage the anti-reflective effect of the coating. Under a microscope, it can be observed that the anti-reflective coating has a porous structure, making it especially susceptible to oil infiltration. The solution is to apply an additional top layer with oil and water resistance properties over the anti-reflective coating, commonly referred to as the waterproof membrane. Moreover, this layer must be extremely thin to ensure it does not change the optical performance of the anti-reflective coating.
