Application of HumiSeal 1C49
HumiSeal® 1C49 is designed for easy application without the need for additional thinning. It should not be mixed with solvents or other thinners. This conformal coating can be applied using various methods, including spraying, brushing, flow coating, or dipping. The time to reach a tack-free state depends on ambient conditions such as temperature and relative humidity, with processing guidelines based on a 50% relative humidity environment.
Dipping
To ensure an even coating, use a controlled immersion and withdrawal rate (5-15 cm/min). Blanketing the dip tank with an inert gas like nitrogen can help extend the pot life.
Spraying
HumiSeal® 1C49 can be applied using conventional spraying equipment in a well-ventilated area to ensure vapors and mist are carried away from the operator. Thinner is not required and should not be used with this product.
Brushing
The uniformity of the film will depend on the component density and the technique used by the operator.
