Conformal coating

Also known as conformal coating or circuit board protective adhesive

Core Application Scenarios and Performance Matching

(I) Electronics Industry

Consumer Electronics

Mobile phone motherboards: Using acrylic conformal coating (thickness 40~60μm), capable of passing IPX7 waterproof tests (no penetration at 1-meter water depth for 30 minutes).

Smartwatches: UV-curing organic silicone (light transmittance >90%) balances screen optical performance with button sealing, resistant to sweat corrosion (pH 4.5~5.5).

Automotive Electronics

Vehicle ECUs: Polyurethane conformal coating (temperature resistance -40℃~150℃) passes ISO 16750-3 vibration tests (20~2000 Hz, 20g acceleration), extending solder joint fatigue life by 2 times.

New Energy Battery BMS: Nano-modified organic silicone (thermal conductivity 0.8 W/m・K) conducts heat away from circuit boards, reducing operating temperature by 15℃.

(II) Extreme Environment Fields

Offshore wind power converter circuit boards: Using fluorocarbon-modified polyurethane adhesive (salt spray test >1000 hours), with a service life of over 10 years in salty mist (Cl⁻ concentration >100 ppm).

Nacelle sensors: Dual-cure organic silicone (UV + moisture) can cure quickly in -60℃ extreme cold environments, ensuring equipment reliability in polar wind power applications.

Aerospace

Satellite circuit boards: Polyimide-modified conformal coating (radiation resistance >10⁶Gy) withstands bombardment by high-energy particles in space while maintaining dielectric loss <0.001.

UAV flight control systems: Low-stress organic silicone (Young's modulus 0.1~0.3 MPa) absorbs vibration energy, preventing solder joint fractures caused by high-frequency vibration.
