Application of 1B73 aerosolConformal Coating
- Allow 48 hours minimum to reach room temperature before using cans stored or received during cold weather.
- When applied in conditions of high ambient humidity, blushing (cloudy white film) may appear. Heating the coated assembly in an oven for 1/2 hour at 76°C eliminates this condition.
- Surface must be cleaned of dirt, wax, grease, flux residues and all similar contaminants for successful application of the coating.
- Mask areas not requiring coating from overspray using suitable non-silicone masking methods or materials.
- Shake can vigorously before using and repeat frequently during use.
- Best results are obtained by spraying from a distance of 30 – 40 cm in light even coats. A film thickness of 25 – 75 microns is sufficient to provide protection.
- To clean nozzle after use, hold can upside down, then press nozzle for a few seconds.
