Bectron® AR 4820 N is a 1-component resin based on polyurethane with moderate viscosity which cures rapidly by reaction with moisture in the atmosphere to form a flexible material suitable for sealing and protection of components and connections on the PCB. Bectron® AR 4820 N satisfies the requirements of ROHS.
FEATURES
Good electrical properties even after water immersion.
Good adhesion on many substrates
Low shrinkage on curing
Withstands low temperature (-45°C)
Resistant to moisture and migration
Resistant to organic and inorganic solvents
APPLICATIONS OF AR 4820 N
Bectron® AR 4820 N is used for chemical protection of PCBs against moisture and contamination and for securing large components on the board against mechanical shock and vibration. It is an effective adhesive on most surfaces of PCBs and electronic components. It has viscosity suitable for thick film coating of large areas selectively on individual components contacts or sealing open connections on the PCB. The applied material will remain in place during curing with no stress on delicate components protected. The cured product is soft and flexible and will not damage sensitive components under thermal shock, including low temperatures.
