Elantas Bectron® PT 4601

Bectron® PT 4601 is a solvent free one-component polyurethane based transparent thick film coating cured by UV irradiation and / or by moisture. It has higher viscosity, thixotropic properties to allow accurate application to selected areas on the PCB. The cured product is elastic with flexibility to low temperature (-40°C) and good adhesion to most substrates. Bectron® PT 4601 and provides excellent insulation properties after several wet storage conditions. Bectron® PT 4601 satisfies the requirements of ROHS.

Applications

Bectron® PT 4601 is versatile VOC-free conformal coating with excellent electrical performance, particularly suitable for electronics such as surface mount devices and hybrids. It provides good protection against moisture, corrosion and migration as well as vibration. Bectron® PT 4601 has flow properties to allow small locations to be coated with minimum flow to other areas.
