Permeation of a protective material is when something you need protection from is able to pass through some protective material to reach you without seriously altering the structure of the protective material. If a hazardous material is able to permeate something you are using for a protective barrier, it is not a good choice for a barrier.

When referring to engineering, permeation is the penetration of a permeate through a solid. A permeate can be a solid, a liquid, or a gas. Permeation can be measured using a minipermeameter.
The best term to describe leakage out of a material or structure is "permeation." This refers to the process of substances such as liquid, gas, or vapor moving through a material in a way that may result in potential leakage.
adjective...e.g. The protective father, A protective material. the adverbial form would be "protectively," I think
Bike tires lose air due to a combination of factors, including small punctures, leaks in the valve, and permeation of air through the tire material over time.
The noun form for the verb permeate is permeation.
Protective coatings are thin layers of material applied to surfaces in order to prevent corrosion, wear, or damage. They can provide resistance to chemicals, weathering, and abrasion, extending the lifespan of the underlying material. Protective coatings are commonly used in industries such as automotive, construction, and aerospace.
The words sought may be permutation or permeation. (see related questions)
permeation through the plasma membrane perhaps?
HELMET : a protective head covering, usually metal or durable material.
It depends on the material involved
There is no such term as perminations. The closest term would be permeation, which is the act of penetrating a substance.
