A great replacement for Dow conformal coating 1-2577 & 1-2620. Low VOC coating – Ideal for moisture, thermal, corrosion and vibration protection.

Fine-L-Kote™ SRV is a high gloss, ultra-clear conformal coating that is moisture and abrasion resistant. This coating offers resilient, mechanical stress-reducing PCB protection, and is low VOC. It extends component life by protecting against adverse environments, with resistance to moisture, salt, fungus, and corrosive vapors. Because of its exceptional dirt, dust, and soil repellency, the coated surfaces remain clean longer.

Fine-L-Kote SRV cures quickly at ambient conditions or heat acceleration can speed in-line processing. Ready-to-use viscosities are available: standard (SRV) for manual and selective spray systems, and high viscosity (SRV 950) for dipping processes.

Fine-L-Kote SRV is available in 2 viscosities:
Standard - ready-to-use at 82cps.
High - for extra thick coating, or to dilute as required.

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 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.

What type of UV light / black light should I use for QC inspection of the final conformal coating?

Conformal coating with UV tracer can be inspected with any typical UV lamp which has wavelength of 320-380 nm.

What solvent can I use to thin this conformal coating?

Heptane can be used as a thinning agent. Make sure it is anhydrous, so contains as little moisture as possible.
