LOCTITE® AA 5832 is a transparent, fluorescent, dual-cure polyacrylate potting sealant that combines UV and secondary moisture curing mechanisms. It offers high resistance to automatic transmission fluids (ATF) and oils, making it suitable for automotive and electronic sealing applications. The product develops rapid functional strength under UV exposure, while full performance evolves over time at ambient conditions. It maintains mechanical integrity after long-term exposure to elevated temperatures and harsh environments.
Potting and sealing of automotive components.
Encapsulation of electronic parts requiring ATF and oil resistance.
Sealing against transmission fluids in under-the-hood environments.
Not recommended for continuous immersion in water or oxygen-rich systems.
