How many types of Humiseal Conformal Coating?
According to primary their solid material composition, Humiseal Conformal Coating can be classified into five primary types: acrylics, polyurethanes (or urethanes), epoxies, silicones, and UV curable.

When it comes to choosing a conformal coating, it’s important to understand that there are numerous options available, and no one solution that is perfect. In order to effectively protect against various environmental factors, a variety of formulations with different performance characteristics have been developed. For example, the HumiSeal range has expanded over the past 50 years to include more than 150 coating formulations that are tailored to meet specific performance and process application needs.
Consequently, it is essential to consider the performance of all conformal coatings as a practical compromise. Enhancing a particular feature such as thermal resistance or operating range will inevitably result in a drawback in another aspect, such as inferior salt or chemical resistance.
