Application of HumiSeal® 1C48

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.  Please contact HumiSeal^® for additional information.

1C48 is designed for application without additional thinning. Solvents or other thinners should not be mixed with 1C48. 1C48 may be applied by spray, brushing, flow coating or dipping. The time required to reach a tack-free state is dependent on ambient conditions such as temperature and relative humidity. The processing guidelines contained in this document were obtained with an ambient relative humidity of 50%.

Brushing
Uniformity of the film depends on component density and the 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® 1C48 may be applied using conventional spraying equipment. 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® 1C48.

Storage
When HumiSeal® 1C48 stored in original containers at 5 ºC to 40 ºC, the shelf life is expected to be 12 months. If the coating is partially used, the container should be purged with dry nitrogen prior to resealing. Once opened, refrigerated storage at below 10 ºC is recommended. Prior to use, allow the product to equilibrate for 24 hours at room temperature (above 16 ºC).

Caution
Application of HumiSeal® 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.

Consult MSDS/SDS prior to use.
