HumiSeal® UV92
HumiSeal® UV92 is a high-performance, soft, one-part UV curable masking material designed for temporary protection during conformal coating applications. With its shear-thinning viscosity profile, HumiSeal® UV92 is easy to apply and cures completely upon exposure to UV light, forming an effective barrier to block coatings from entering designated keep-out areas. This product offers excellent solvent resistance, allowing for clean and selective removal without damaging surrounding coatings. Engineered to withstand intermittent thermal exposure up to 150°C, HumiSeal® UV92 provides reliable performance in demanding processing environments. Fully compliant with REACH and RoHS regulations, HumiSeal® UV92 is available in both bulk packaging and convenient syringes, making it an ideal solution for electronics manufacturers seeking precision, safety, and ease of use.
