Aeronautics

Hydrophobic, oleophobic, and RF-transparent coatings engineered for the full envelope of avionics and airframe demands.

The Problem

Avionics electronics operate in conditions no ground-based system experiences: extreme temperature cycling, pressure differentials, condensation at altitude, vibration loads, and corrosive contaminants ranging from jet fuel to de-icing fluid. Moisture ingress into avionics connectors, corrosion on PCBAs in unpressurised bays, and radome surface degradation are documented failure modes. As India’s civil aviation sector expands and domestic MRO capability grows, locally available avionics-grade surface protection is a baseline requirement.

The Solution

Protection that performs across the full flight envelope.

ViriDyn’s coatings address avionics protection at two levels. For radome and antenna surfaces, superhydrophobic and RF-transparent coatings prevent rain fade and signal attenuation while resisting salt fog and ice. For internal avionics electronics, conformal nano-coatings provide hydrophobic, oleophobic, and corrosion-resistant protection on PCBAs, connectors, and wiring harnesses at less than 1 micron thickness — no impact on thermal or electrical performance. Compatible with temperature ranges and chemical environments encountered in both commercial and military aviation. Field restoration treatments are available for MRO applications.

What We Protect

  • Avionics PCBAs and flight control electronics
  • Airborne radomes — nose, belly, and dorsal installations
  • Communications and navigation hardware
  • Connectors, wiring harnesses, and pin assemblies
  • Sensor housings and pitot system electronics
  • MRO applications — field restoration of deployed systems

What Changes

Improves:

  • Moisture and corrosion resistance across temperature cycling conditions
  • Rain fade protection for airborne radomes and antenna systems
  • Salt-fog resistance for coastal and maritime aviation operations
  • Connector and harness protection against condensation ingress
  • MRO efficiency with field-applicable restoration treatments

Reduces:

  • Moisture ingress into avionics connectors at altitude
  • Corrosion on PCBAs in unpressurised avionics bays
  • Rain fade attenuation on airborne radar and comms systems
  • Salt-fog degradation on external antenna and radome surfaces
  • Unscheduled maintenance events caused by surface failure
