VIRIDYN DX
The invisible armour your circuit boards need — zero masking, zero curing.
VIRIDYN DX
A hard, PFAS-free transparent shell — for surfaces that take punishment.
The Problem
Surfaces facing physical wear need a coating that lasts. Defence, medical, and export applications increasingly require a proven PFAS-free chemistry.
What It Does
A fluorocarbon-free siloxane that cures to a hard 7H–9H shell. Repels water, resists corrosive gases, and remains optically clear under UV exposure.
Use Cases
- Optical sensors, cameras, and precision lenses
- Touchscreens and displays in ruggedised electronics
- PCBAs in defence and aerospace applications requiring PFAS-free coatings
- Medical device surfaces and diagnostic instrument housings
- Filtration membranes requiring hydrophobicity without pore blockage
Compliance Notes
FAS-free. Fluorocarbon-free. Non-toxic when dry. Non-flammable dry film. Available in flammable (ethyl acetate, tert-butyl acetate) and non-flammable (AS300) solvent options.
Key Features
- Hard (7H–9H pencil hardness) — durable enough for surfaces that face physical contact or field handling
- PFAS-free and fluorocarbon-free — compliant with tightening global regulations; relevant for defence export and medical applications in India
- Hydrophobic (>100° water contact angle) — water rolls off; corrosion and condensation protection
- Temperature stable to >500°C — suitable for high-temperature environments and components near heat sources
- Optically clear (refractive index ~1.4) — no yellowing under UV; suitable for lenses, sensors, and transparent surfaces
- Maintains membrane porosity — can be used on filtration substrates without degrading airflow
