HumiSeal® UV92 is a soft, one part, UV curable masking material. HumiSeal® UV92 applies easily because of its shearing thinning viscosity profile and is 100% cured by exposure to UV to provide a temporary barrier to prevent ingress of coatings into keep out areas. HumiSeal® UV92 has excellent solvent resistance that provides selective release from conformal coating. HumiSeal® UV92 will survive intermittent exposure to temperatures up to 150°C. HumiSeal® UV92 is REACH and RoHS compliant and available in bulk and Syringes.
