  • Moisture-Curing Formulation
  • Powertrain Fluid Resistance

Product Description

LOCTITE® AA 5810A™ is a one-component, moisture-curing polyacrylate adhesive sealant formulated for formed-in-place gasketing applications. This black, non-silicone, oxime-free material is designed for flange sealing applications where resistance to powertrain fluids is important. Its heavy-body, thixotropic consistency supports low-pressure leak-testing prior to cure while helping maintain bead placement after application. Typical applications include cast metal, stamped steel, and molded plastic covers used in engines, transmissions, axles, and selected electronic housings requiring durable environmental sealing.

Key features

  • Non-silicone polyacrylate chemistry: Helps avoid silicone-related lubricant foaming concerns while providing reliable sealing performance.
  • Moisture-curing formulation: Cures at room temperature without mixing and develops strength through atmospheric moisture exposure.
  • Powertrain fluid resistance: Exhibits resistance to engine oils, transmission fluids, and gear oils in demanding sealing environments.

Applications / Suitable for

  • Engine covers and housings
  • Transmission covers and assemblies
  • Axle sealing applications
  • Cast metal flanges
  • Stamped steel covers
  • Molded plastic covers and housings
  • Electronic component enclosures
