Description
Circuit boards exposed to humidity, condensation or aggressive atmospheres need a tight insulating layer. ECS Urethane Clear forms an elastic, transparent polyurethane film that keeps its adhesion from -40 °C to +120 °C.
Benefits in use
- High surface and volume resistance plus good dielectric strength insulate conductor tracks reliably.
- Low dielectric constant and low loss factors, so the circuit is hardly affected electrically.
- Chemical cross-linking during drying, then resistant to moisture, diluted acids and alkalis.
- Elastic, abrasion resistant and adherent from -40 °C to +120 °C, also under thermal cycling.
- Transparent, components and markings stay readable after coating.
Applications
Conformal coating of PCBs and assemblies in controls, power supplies, vehicle and outdoor electronics, insulation of windings and terminals, touch-up after repairs.
Pack sizes
Urethane Clear is also available as a 1 litre can and a 400 ml spray for smaller quantities and touch-ups.
