Application of HumiSeal 1C49LV
Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue, “no clean” materials.
Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level.
Brushing
- Uniformity of the film depends on component density and operator's technique.
Dipping
- A controlled rate of immersion and withdrawal (5-15 cm/min) will ensure even deposition of the coating and ultimately a uniform film.
- Blanketing dip tanks with an inert gas such as nitrogen can extend pot life.
Spraying
- HumiSeal 1C49LV may be applied using most conventional spraying equipment.
- When in doubt, test the ability of the spray equipment before applying coating to production boards.
- Spraying should be done in an environment with adequate ventilation so that the vapour and mist are carried away from the operator.
- The use of thinner is not required or recommended for HumiSeal 1C49LV.
HumiSeal 1C49LV Application notes
HumiSeal 1C49LV Storage
- HumiSeal 1C49LV should be stored at 27°C or below in tightly closed containers away from direct sunlight.
- If coating is partially used, the container should be purged with dry nitrogen prior to resealing.
- Prior to use, allow the product to equilibrate for 24 hours at room temperature.
HumiSeal 1C49LV Caution
- Application of HumiSeal 1C49LV Conformal Coatings should be carried out in accordance with local and National Health and Safety regulations.
- Use only in well-ventilated areas to avoid inhalation of vapours or spray. Avoid contact with skin and eyes.
