HumiSeal 1C49LV is a low-viscosity, moisture-curing silicone conformal coating that you can spray. It gives the strong protection of silicone in an easy-to-apply form. In addition, it is solvent-free and VOC-free, which makes it a cleaner choice for your coating line.
Why choose HumiSeal 1C49LV?
Many silicone coatings are thick and hard to spray. For this reason, 1C49LV has a low viscosity of 550 cps. It flows easily to give thin, even coverage over complex boards.
Once cured, it forms a tough barrier against moisture, humidity and airborne contaminants. It also stays very flexible from -65°C up to 200°C. Therefore, it protects electronics that face thermal shock or vibration.
The coating contains a UV tracer, so inspection under black light is quick. It cures at room temperature, or you can speed it up with heat. As a result, it fits a wide range of production setups.

Where to use HumiSeal 1C49LV
This coating suits high-reliability electronics in tough conditions. For example, it is a good fit for:
- Automotive electronics
- Aerospace assemblies
- Industrial controls
- Boards exposed to heat, shock or vibration
Tips for best results
First, make sure boards are clean and dry before coating. Next, mask any connectors or parts that must stay uncoated. Then spray thin, even layers rather than one heavy coat. Finally, check coverage under UV light once the coating has cured.
