Application of HumiSeal 1B31 Aerosol:

1. Allow 48 hours minimum to reach room temperature before using cans stored or received during cold weather.
2. 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.
3. Surface must be cleaned of dirt, wax, grease, flux residues and all similar contaminants for successful application of the coating.
4. Mask areas not requiring coating from overspray using suitable non-silicone masking methods or materials.
5. Shake can vigorously before using and repeat frequently during use.
6. 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.
7. To clean nozzle after use, hold can upside down, then press nozzle for a few seconds.
