Applications

LOCTITE® AA 3008 – UV Acrylic Adhesive – Low viscosity bonding and sealing for ammunition applications

  • Item Name: LOCTITE® AA 3008

  • Manufacturer: Henkel

  • Technologies: Acrylic, Diacrylate, One-component

  • Color: Red, transparent (fluorescent under UV light)

  • Cure Type: Ultraviolet (UV) / Visible light, Secondary activator, Anaerobic (metal substrates)

  • Package Size: Contact to Techniq VN for details.

  • Shelf Life: Contact to Techniq VN for details.

1. Product Overview

LOCTITE® AA 3008 is a low-viscosity, red transparent diacrylate adhesive that cures rapidly under UV or visible light, with secondary anaerobic or activator-assisted cure. It features high capillarity, positive fluorescence under UV, and is specifically designed for sealing ammunition. The product offers fast fixture time, reliable bonding, and effective sealing performance, particularly with metallic substrates.


2. Applications

  • Sealing and bonding of ammunition components.

  • Suitable for metallic substrates where anaerobic cure can occur.

  • General bonding and sealing tasks requiring fast UV/visible light curing.

  • Effective in applications needing capillary action and high penetration.

3. Typical Properties

Property Condition Value
Uncured Appearance Red, transparent
Specific Gravity (23 °C) 1.08
Viscosity (25 °C, Spindle 1, 30 rpm) 12 mPa·s
Cure Method UV/Visible light, secondary anaerobic/activator
Tack Free Time (30 mW/cm², 365 nm) 4 sec
Fixture Time (25 mW/cm², 365 nm, glass slides) 1 sec
Cured Lap Shear Strength (Acrylic, UV cure) 0.5 N/mm² (73 lb/in) – substrate failure
Lap Shear Strength (Steel, Activator SF 7649, 23 h) 970 N/mm²* (970 psi)
Compressive Shear Strength (Steel pins & collars) 9.0 N/mm² (1,300 psi)

*The reported steel lap shear value in the TDS (970 N/mm²) appears unusually high and may represent a misprint; typical values are usually in the range of single to tens of N/mm².
