Coating lacquers Polyurethane Bectron® PT 48, moisture-curing

€0,00

Bectron® PT 48.. are one-component, moisture-wetting polyurethane-based thick film coatings for SMD and hybrid printed circuit boards. The cured film is elastic over a temperature range of -50 °C to + 120 °C to withstand vibrations and with good adhesion to most substrates. They are resistant to solvents, dilute acids and alkalis and provide excellent protection against moisture and corrosion, even in extremely humid conditions. The various viscosity grades, from approx. 1400 mPas to thixotropic viscosity grades, provide a wide range of applications and processes. The coatings can also be used as adhesives to secure the components.
