1. Product Overview

LOCTITE® AA 5810B™ is a single-component, non-silicone, oxime-free polyacrylate adhesive/sealant. It cures by moisture at room temperature, forming a flexible, oil-resistant gasket. Designed for flange sealing in engines, transmissions, axles, and electronic housings, it tolerates joint movement and maintains non-sagging properties.


2. Applications

  • Flange sealing with superior hot oil and hydrocarbon resistance.

  • Cast metal, stamped steel, and molded plastic covers (engines, transmissions, axles).

  • Sealing plastic and metal housings for electronic components.

  • Applications requiring non-foaming behavior in lubricants and resistance to powertrain fluids.
