Application of HumiSeal 1B18 Aerosol
- 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.
- Cleanliness of the substrate is extremely important to the successful application of a conformal coating. Surfaces should be free of moisture, dirt, wax, grease and all other contaminants.
- Otherwise, ionic or organic residues on the substrate could be trapped under the coating and cause problems with adhesion or electrical properties.
- The highest long term reliability for a coated printed circuit assembly will be when the conformal coating is applied over a clean, dry substrate.
- The application of conformal coatings over no clean flux is a common practice.
- The user should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials and process conditions. Please contact HumiSeal for additional information.
- Mask areas not requiring coating 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 a distance of 30 - 40cm 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.
HumiSeal 1B18 Aerosol Caution
- Application of HumiSeal Conformal Coatings should be carried out in accordance with local and National Health and Safety regulations.
- The solvents in HumiSeal Conformal Coatings are flammable. Material should not be used in presence of open flame or sparks.
- Use only in well-ventilated areas to avoid inhalation of vapours or spray. Avoid contact with skin and eyes.
