HumiSeal 1C49 Description

HumiSeal 1C49 is a moisture curing, high build, VOC-free silicone conformal coating which provides excellent moisture and environmental protection for printed circuit assemblies.

HumiSeal 1C49 is solvent free. The coating demonstrates outstanding flexibility, fluoresces under UV light for ease of inspection and can be repaired.
It can be cured at room or at elevated temperatures.
It is MIL-I-46058C qualified, IPC-CC-830 and RoHS Directive 2011/65/EU compliant, and recognized under UL File Number E105698.

Application of HumiSeal 1C49

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 Hictech for additional information.

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 1C49 may be applied using spraying equipment designed for high viscosity coatings.
Attempting to apply the material using conventional spray equipment may result in bubbles in the cured HumiSeal 1C49 coating.
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 the operator.
The use of thinner is not required or recommended for HumiSeal 1C49.

Storage

HumiSeal 1C49 should be stored at 27°C or below in tightly closed containers away 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.

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.
