HumiSeal UV20Gel: Durability and Reliability for PCBs Under Thermal Stress

Humiseal UV20Gel has been successful in protecting PCB components from vibration and environmental conditions when traditional conformal coatings alone are not up to the task. This protection depends on the polymer maintaining tensile and elongation strength and flexibility characteristics over time. Humiseal scientists have recognized the need for data regarding performance over time and under temperature and humidity conditions typical to many of these industries. As can be identified in the data and testing within this presentation, Humiseal UV20Gel has shown consistent tensile and elongation properties when tested at continuous operating temperatures as high as 125 C for 400 hours and combined conditions of 85 C and 85% RH for up to 2000 hours.
