3708 SIL-26 Silicone Conformal Coating - 5Ltr

Micron Aerosols SIL-26 Silicone Conformal Coating is a premium high-performance protective coating engineered for electronic assemblies, printed circuit boards (PCBs), and sensitive electrical components operating in demanding environments. Formulated with advanced moisture-curable silicone technology, SIL-26 forms a uniform, flexible, and highly dielectric protective film that safeguards electronic circuits against moisture, humidity, dust, oxidation, salt mist, and environmental contaminants. Designed for long-term reliability, the coating provides excellent thermal stability, electrical insulation, and resistance to environmental stress, helping extend the operational life and performance of electronic systems exposed to harsh industrial, automotive, telecom, aerospace, and outdoor conditions. Its flexible silicone-based chemistry accommodates thermal expansion and vibration without cracking, making it ideal for applications requiring durable protection under fluctuating temperatures and continuous operating conditions. SIL-26 can be applied by brushing, dipping, or selective coating methods, delivering consistent coverage and strong adhesion across complex PCB assemblies and electronic components. Key Features & Benefits Moisture-curable silicone conformal coating Excellent dielectric and insulation properties Protects against moisture, humidity, dust, and oxidation Flexible coating resistant to thermal cycling and vibration High-temperature and environmental stability Enhances reliability and service life of electronic assemblies Suitable for complex PCB geometries and dense circuitry Excellent adhesion on electronic substrates Typical Applications Printed Circuit Boards (PCBs) Electronic assemblies and control systems Industrial electronics Automotive electronics Telecom and networking equipment LED drivers and power supplies Aerospace and defense electronics Outdoor and high-humidity electronic systems Directions for Use Ensure the PCB or electronic assembly is clean, dry, and free from oil, flux residues, dust, and contaminants before application. The coating may be applied by brushing or dipping. For dip coating, immerse the PCB in the solution for approximately 5 minutes to ensure uniform coverage. Allow excess coating to drain before drying. Dry the coated assembly for approximately 15–20 minutes under ambient conditions or as required by the process environment. Safety & Handling Use only in well-ventilated areas. Avoid contact with eyes and mouth. In case of eye contact, rinse thoroughly with water. If swallowed, do not induce vomiting; seek immediate medical attention. Keep out of reach of children. Refer to the Safety Data Sheet (SDS) for complete safety, handling, and storage information.
