3M High-Temperature Masking Liquid 2538UV

3M™ High-Temperature Masking Liquid 2538UV is a UV fluorescing olefin hybrid adhesive that is specially formulated to offer excellent high-temperature resistance and low slump during processing. This specially formulated UV hot melt adhesive provides a clearly detectable means for product location and removes cleanly from various electronic substrates by peeling (even after 10 min @ 260°C (500°F)). The non-silicone formulation reduces the potential for silicone contamination which can interfere with subsequent bonding or conformal coating processes. This high-temperature resistance adhesive also possesses excellent chemical resistance and should be considered for demanding chemical masking applications.
FEATURES:
Excellent conformability upon dispensing
High-temperature slump resistance
Good wet out on various substrates such as FR4, metals and glass
Good chemical resistance to conformal coatings, acids and bases ingression
Fast process time
Clean removal
Stable dielectric properties
Silicone free
UV detectable
APPLICATIONS:
Protection of sensitive areas and component on printed circuit boards during conformal coating processes
Masking and sealing of electronic components
