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.
