Product Introduction
DCB is a flexible, black opaque modified alkyd conformal coating specifically engineered for protecting electronic circuitry.Formulated to meet the highest defense standards in Europe and the US, it operates reliably in extreme temperatures (-70°C to +200°C) and is UL94 V-1 flammability certified.The coating offers superior solvent resistance (optimized at 120°C curing) and can be applied via spray, dip, or brush methods.
Enhanced Properties
DCB resists solvents used in aerospace/automotive industries. The heat-cured coating operates stably from -70°C to +200°C, with maximum solvent resistance achieved at 120°C curing.
Offers flexible curing schedules: Ambient (24h@25°C), Commercial (2h@20°C + 2h@90°C), Military (12h@25°C + 24h@90°C), meeting varied application demands.
Applicable by spraying, dipping or brushing (25-75μm thickness). Spraying requires 1:1 dilution with DCT thinners to 50-80mPa·s; dipping viscosity must be 180-250mPa·s.
Application Scenarios
Validated by Electrolube Tech Bulletin SCC3/2019 and industry cases:
- Aerospace: Satellite power control modules resistant to jet fuel (Jet A) and thermal cycling (-65°C to 150°C);
- Military Electronics: PCB protection in armored vehicle comms systems (MIL-STD-810G vibration certified);
- Automotive: Engine Control Units (ECU) resistant to gasoline/diesel and under-hood temperatures;
- Industrial: Oil drilling sensor circuits protected against H₂S corrosive gas and salt spray.
