SYNERPLUS ELECTRA KOTE 210

(PCB COATING SPRAY)
PCB Coating Spray is a high-performance protective solution designed to safeguard printed circuit boards (PCBs) from environmental factors, physical damage, and electrical degradation. This spray forms a durable, insulating layer that enhances the reliability, longevity, and operational safety of electronic devices by protecting them from moisture, dust, corrosion, and other contaminants.

Key Features

  • Conformal Coating: PCB Coating Spray provides a uniform conformal coating that adheres seamlessly to the surface of electronic components and circuit traces. This coating offers comprehensive protection without affecting the functionality or electrical performance of the device.
  • Dielectric Insulation: The coating delivers superior dielectric properties, ensuring that the electronic components are electrically insulated from external environments. This helps prevent short circuits, signal interference, and arcing between conductive elements.
  • Moisture and Corrosion Resistance: The spray is specially formulated to resist moisture, humidity, and corrosive agents, such as salt, acids, and alkalis. This makes it an ideal solution for electronic devices used in harsh or humid environments, ensuring they remain free from corrosion and electrical degradation over time.
  • Protection Against Thermal Stress: PCB Coating Spray can withstand a wide range of temperatures, offering protection during both high- and low-temperature operating conditions. This thermal stability ensures that the coating remains intact even in demanding applications, such as automotive, aerospace, and industrial electronics.
  • UV and Chemical Resistance: The coating has excellent resistance to ultraviolet (UV) radiation, protecting it from yellowing or degradation due to sun exposure. Additionally, it resists a variety of chemicals, solvents, and oils, further protecting the PCB in environments where exposure to harsh substances is likely.
  • Thin, Transparent Film: Upon application, the PCB Coating Spray forms a thin, transparent film that preserves the appearance of the board and allows for visual inspection of components without removal. This feature is essential for maintenance and troubleshooting in complex electronics.
  • Quick Drying and Curing: The spray dries rapidly after application, forming a protective film in minutes. Depending on the type of formulation, it may require additional curing time, which can be accelerated using heat for improved coating performance.”

Technical Benefits

  • Enhanced Electrical Insulation: By insulating sensitive components and traces, PCB Coating Spray helps maintain signal integrity and prevent leakage currents, which could otherwise cause malfunctions or performance issues in electronic circuits.
  • Corrosion Prevention: The coating forms a barrier against contaminants that can lead to corrosion, including water, salt, and aggressive chemicals. This is especially important in applications exposed to marine environments, industrial settings, or outdoor conditions.
  • Extended Component Life: Protecting components from environmental stressors helps to prolong the operational life of the PCB, reducing the likelihood of failure due to environmental factors such as moisture ingress or dust accumulation.
  • Minimized Risk of Failure: By preventing short circuits, arcing, and signal degradation, PCB Coating Spray significantly reduces the risk of failure, making it crucial for safety-critical applications such as medical devices, automotive electronics, and aerospace systems.
  • Vibration and Shock Protection: The conformal nature of the coating also provides some level of physical protection against mechanical stress, such as vibration or shocks, which are common in mobile electronics and machinery.
  • Improved Thermal Management: While providing protection, some formulations of PCB Coating Spray are designed to allow for heat dissipation, ensuring that components do not overheat and maintain stable operation.”

Application Instructions

  • Preparation:Ensure the PCB is clean, dry, and free from any dust, grease, or contaminants. If necessary, clean the board with a PCB cleaner spray before coating.Mask off any areas that should not be coated, such as connectors or components requiring electrical conductivity.
  • Shake the Can:Shake the PCB Coating Spray can thoroughly before use to ensure that the coating material is well-mixed and will apply evenly.
  • Application:Hold the can approximately 8-12 inches away from the PCB. Apply a light, even coat, making sure to cover all areas of the board.For best results, apply the coating in multiple light layers rather than one thick layer. Allow each coat to dry before applying the next.
  • Drying and Curing:Allow the coating to dry for 10-15 minutes between coats. Once the final coat has been applied, let the board dry completely for at least 30 minutes.For enhanced performance, some coatings may require heat curing. Follow the manufacturer’s guidelines for temperature and curing time.
  • Inspection:After drying, inspect the board for complete coverage. Ensure no exposed areas are left unprotected. Additional coats may be applied if necessary.
  • Rework (if needed):If rework is required, use a suitable solvent or apply heat to soften the coating, allowing for component removal or replacement.”

Safety Precautions

  • Personal Protective Equipment (PPE): Use gloves, safety goggles, and protective clothing to avoid contact with skin and eyes.
  • Ventilation: Always apply PCB Coating Spray in a well-ventilated area or under a fume hood to avoid inhalation of fumes.
  • Flammability: The coating may be flammable; avoid use near open flames or high-heat sources.
  • Storage: Store the spray in a cool, dry place, away from direct sunlight or extreme temperatures.”
