LOCTITE EA 9306NA

Main features

  • One-Component, Heat-Curing Epoxy Paste
  • Low-Exotherm Bonding Processing
  • 34.5 MPa Aluminum Lap Shear

Product Description

LOCTITE® EA 9306NA Epoxy Paste Adhesive is a gray, thixotropic, one-component epoxy adhesive that develops bonded-joint performance through heat cure. Its sag-resistant consistency supports controlled placement, while its low-exotherm formulation is suited to bonding processes where heat generation is a concern. The adhesive provides tensile lap shear strength across test temperatures from -55°C to 82°C and is also documented for coil and potting applications.

Key features

  • One-component heat-cure system: Supplied ready to use after warming to room temperature, without component mixing.
  • Sag-resistant thixotropic paste: Supports controlled adhesive placement where flow or movement must be limited.
  • Temperature-dependent bond performance: Typical tensile lap shear strength ranges from 27.6 to 34.5 MPa on phosphoric-acid-anodized 2024-T3 clad aluminum.

Applications / Suitable for

  • Bonding applications requiring sag resistance
  • Bonding processes where low exotherm is important
  • Coil applications
  • Potting applications

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
500,000 to 1,300,000 mPa.s
