Bectron® PT 4700 N is a solvent free one-component polyurethane based transparent thick film coating cured by UV irradiation and / or by moisture. The cured product is elastic with flexibility down to low temperature (-40°C) and good adhesion to most substrates. Bectron® PT 4700 N provides excellent insulation properties after severe wet storage conditions. Bectron® PT 4700 N satisfies the requirements of REACh and ROHS. Bectron® PT 4700 N can survive temperature shock and temperature cycling resistance such as -40 to +125°C (e.g. IPC Test 2.6.7.1 Class 2) for more than 500 cycles.
