Fine-L-Kote™ LED2 is specifically designed and formulated for light emitting diode applications, where a completely transparent coating is required to provide a tough, extremely flexible protective coating. It provides the highest flexibility for extreme temperatures on the flex and rigid circuitry found on LED displays and provides an outstanding non-stick surface for soil repellency.
Cured coatings are hydrolytically stable and retain their physical electrical properties after high temperature and humidity exposure, without interfering with light wavelength or intensity. Fine-L-Kote LED2 will not stress delicate circuit components and meets the performance parameters (without UV traceability) of MIL-I-46058C, Type SR but is not qualified on QPL-46058.
Silicone conformal coating provides excellent protection in a very wide temperature range. SR provides good chemical resistance, moisture and salt spray resistance, and is very flexible. Silicone conformal coating isn’t abrasion resistant because of its rubbery nature, but that property does make it resilient against vibrational stresses. Silicone coatings are commonly used in high humidity environments, like outdoor signage.
