1. Loss of Hydrophobic Protection
- Surface treatments wear away – loses ability to repel liquid water.
- Moisture penetrates microporous membrane, causing severe condensation.
- Leads to potential water damage to internal electronic circuits.
2. Seal Degradation & Leakage
- Elastomeric gaskets – suffer compression loss, cracking, or hardening from weathering and thermal cycling.
- Destroys watertight barrier.
- Allows dust, moisture, and harsh chemicals to freely infiltrate enclosure.
3. Airflow Restriction & Clogging
- Continuous debris exposure – clogs pores or causes structural collapse of filtration membrane.
- Severely restricts necessary air exchange.
- Leads to dangerous pressure buildup and overheating of sensitive components.
4. Material Brittleness & Structural Failure
- Prolonged UV and temperature fluctuation – engineering plastics become extremely brittle.
- Housing vulnerable to cracking or shattering.
- Compromises overall mechanical integrity of the component.
