Specifically formulated for precision dispensing and jetting applications, HumiSeal UV40HV is a high-viscosity version of the popular UV40 acrylated polyurethane coating. With a viscosity of 3,700 cPs, this formula provides excellent edge coverage and prevents excessive slumping on high-profile components, ensuring a consistent protective layer across the entire PCB. It shares the same rapid UV-curing capabilities as the standard formula, reaching a tack-free state instantly, while the secondary moisture-cure mechanism ensures total integrity in shadowed regions over several days. UV40HV maintains exceptional chemical resistance and moisture-barrier properties, offering a robust shield for electronics in automotive and aerospace sectors. Its high-solids content and precision-oriented rheology make it the definitive choice for manufacturers utilizing automated jetting systems for targeted, high-performance conformal coating.
