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 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.
