Revestimiento for industrial control boards
Industrial control boards used in Montaje de PCB y Montaje SMT operate in harsh environments that often include humidity, dust, chemicals, vibration, and temperature fluctuations. Choosing the right Revestimiento conforme is essential to ensure long-term reliability and performance.

Best overall: polyurethane (urethane) Revestimiento conforme
Polyurethane is one of the most commonly used coatings for industrial control boards due to its strong resistance to chemicals and environmental contaminants.
Ventajas clave:
- Excelente resistencia química (solvents, oils, fuels)
- Strong protection against moisture and corrosion
- Good mechanical durability
- Suitable for factory and industrial environments
This makes polyurethane ideal for control systems exposed to industrial pollutants and harsh operating conditions in Montaje de PCB.
Best for temperature and flexibility: silicone Revestimiento conforme
Silicone is another top choice, especially when temperature variation and vibration are significant.
Ventajas clave:
- Amplia gama de temperaturas (-55°C a 200°C+)
- High flexibility → resists cracking under vibration
- Good moisture and humidity resistance
- Performs well in outdoor or semi-industrial environments
Silicone is often used in industrial automation systems that experience both heat and mechanical stress en Montaje SMT.
Opción de gama alta: parileno Revestimiento conforme
For critical industrial applications, parylene provides the highest level of protection.
Ventajas clave:
- Pinhole-free, uniform coating
- Superior resistance to moisture, chemicals, and corrosion
- Excellent performance in extreme environments
However, due to higher cost and specialized processing, it is typically reserved for high-reliability or mission-critical control systems.
Other coatings in industrial use
Acrílico
- Cost-effective and easy to apply
- Adecuado para mild industrial environments
- Limited resistance to chemicals and harsh conditions
Epoxi
- Resistente y duradero
- Good for mechanical protection
- Less suitable due to rigidez y escasa reelaborabilidad
Cómo elegir el revestimiento adecuado
- Chemical exposure (oil, solvent, factory gases) → Polyurethane (best choice)
- High temperature + vibration → Silicone
- Extreme or mission-critical environments → Parylene
- Cost-sensitive, low-risk applications → Acrylic
Conclusión final
For most industrial control boards in Montaje de PCB y Montaje SMT, polyurethane Conformal Coating is the best overall choice due to its excellent chemical and environmental resistance. Silicone is ideal for high-temperature and vibration-prone environments, while parylene offers premium protection for critical systems.
