Solvent-free conformal coating for PCBs
A highly stable, one-part, material with an excellent shelf life of six months, Hysol PC40-UMF is UV curable in 30 seconds with a built-in secondary moisture cure mechanism that eliminates the risk of incomplete cure. The new conformal coating material is said to offer superior wetting and wicking performance and its rheology has been optimized for the industry’s latest dispensing technologies. The dispense capability of Hysol PC-40UMF enables assembly specialists to more easily apply the material on selected areas and prevent deposition on unwanted areas of the PCB. Once Hysol PC40-UMF has been applied to the PCB, inspection is also aided by its unique formulation with enhanced fluorescence under black light.
