VIRIDYN 101-M
Keeps membranes repellent to water and oils — without blocking airflow out.
VIRIDYN 101-M
Keeps membranes repellent to water and oils — without blocking airflow out.
The Problem
Membranes must block liquids but still pass air and gas. Standard treatments often degrade permeability — leaving filtration performance compromised.
What It Does
Coats membrane surfaces to repel water and oils without filling the pores. Air flow, gas flow, and acoustic performance are all preserved post-coating.
Use Cases
- Automotive headlamp and electric motor venting membranes
- EV battery pack pressure venting
- IV filter vents and medical suction device membranes
- Consumer electronics waterproofing (earphones, hearing aids, wearables)
- Gas sensors and industrial filtration systems
- Vented packaging for battery and chemical industries
Compliance Notes
Low toxicity. Non-ozone depleting. RoHS compliant. Flammability: UL94 V-0. Available in flammable and non-flammable solvent options.
Key Features
- Hydrophobic + Oleophobic (Grade 8) — repels water and oils simultaneously; suitable for contaminated environments
- Retains permeability — air, gas, and acoustic performance of the membrane substrate is maintained post-coating
- Ultra-thin (0.3–0.6 µm) — coating sits on the surface; does not enter or block pores
- Fast dry — 30 to 120 seconds at room temperature; no curing equipment needed
- RF-transparent — suitable for membranes used in antenna or wireless housings
- RoHS compliant, low toxicity, non-ozone depleting — safe for medical and consumer electronics applications
