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
