UE 55-0500/3

UV Spray coatings series

UE 55-0500/3 is a UV cell coating for the BMW Gen5 platform (project period 2018 - 2030). It is applied by hot spray at 40℃, target film thickness 110 µm (70-145 µm). Key performance includes 3000 VDC BOL/EOL dielectric strength, insulation resistance >100GΩ BOL/EOL, very high anti sagging ability, GT0 adhesion, lap-shear BOL/EOL >8MPa. It offers coolant resistance. Validated by EOL1 240h 40℃/100%RH, EOL2 climate cycle test 30 days. It is REACH/RoHS confirm, no toxic or CMR category 1 ingredients. Online recycling utilization rate up to 95%, easy laser decoating.
