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.

What is the difference between full cure and tack-free cure?

Full cure is when it meets all the final specifications. There might be some out-gassing, but it will be as hard as it is going to be, and adhesion is as good as it gets.  Tack-free is as the name suggests, not sticky so you can move it along the assembly process.

What does 2-step curing mean?
That just means you break the accelerated curing process into 2 stages. You basically ramp up the heat so the coating has an opportunity to level. Otherwise, you can get a wrinkling or orange peel texture. That texture doesn’t affect performance, just aesthetic. This is not an issue when curing in ambient conditions.
What is the difference between dielectric strength and dielectric withstand voltage?

The dielectric strength is material intrinsic property and withstand voltage is surface property which depend on thickness of the material. They can be slightly different for thicker materials, but for conformal coating, the two numbers should be very close or the same. That is because we test coating at 3-5 mils thickness, calculate, then report the value per mil.
