HumiSeal UV92 UV Curable Masking GelHumiSeal UV92 UV Curable Masking Gel

HumiSeal UV92 UV Curable Masking Gel is a soft, one part UV curable masking material. UV92 is a thixotropic paste that 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 to keep out areas.

HumiSeal UV92 has excellent solvent resistance that provides selective release from conformal coating. The gel also has the ability to survive intermittent exposure to temperatures up to 150°C and is REACH and RoHS compliant.
