LOCTITE EA 9497 is a two-part structural epoxy adhesive supplied as a resin and hardener system for high-strength bonding applications. For composite fabricators and industrial assemblers who already source resins, gasket sealants, and instant adhesives from Thousands Technology, LOCTITE EA 9497 fills a role where a structural epoxy with a working room-temperature cure is needed rather than a fast-setting instant adhesive. This page summarizes the documented properties and application steps for LOCTITE EA 9497 to support sourcing decisions.
Typical Properties of LOCTITE EA 9497 (Uncured Material)
The properties below are documented for the uncured resin and hardener components and help buyers compare this adhesive against other structural epoxies for a given bonding application.
| Property | Resin | Hardener |
|---|---|---|
| Specific Gravity @ 25 °C | 2.05 to 2.13 | 2.02 to 2.1 |
| Casson Viscosity, Cone & Plate (25 °C, Shear Rate 0-40 s⁻¹) | 5 to 16 Pa·s | 8 to 24 Pa·s |
| Flash Point | See SDS | See SDS |
Mixing and Application Steps for LOCTITE EA 9497
Correct mixing ratio and working-time management are essential for getting reliable results from this structural adhesive. The documented directions for use are as follows:
- For best performance, surfaces for bonding should be clean, dry, and free of grease. For high-strength structural bonds, special surface treatments can increase bond strength and durability.
- Resin and hardener must be blended before use. Using bulk containers, mix thoroughly by weight or volume in the proportions specified in the Product Description Matrix. For hand mixing, weigh or measure out the desired amount of resin and hardener and mix thoroughly for approximately 15 seconds after a uniform color is obtained.
- Do not mix quantities greater than 4 kg in mass, as excessive heat build-up can occur. Mixing smaller quantities minimizes the heat build-up.
- Apply the adhesive as quickly as possible after mixing to one surface to be joined. For maximum bond strength, apply adhesive evenly to both surfaces, and assemble parts immediately after the mixed adhesive has been applied.
- Working life of the mixed adhesive is 3 to 4 hours at 22 °C. Higher temperature and larger quantities will shorten this working time.
- Keep the assembled parts from moving during cure, and allow the joint to develop full strength before subjecting it to any service loads.
- Excess uncured adhesive can be wiped away with an organic solvent such as acetone.
- After use and before the adhesive hardens, mixing and application equipment should be cleaned with hot soapy water.
Working Life and Batch Size Planning
Because the working life of LOCTITE EA 9497 is only 3 to 4 hours at 22 °C, and larger mixed quantities generate more heat that shortens this window further, production teams should plan batch sizes and application sequencing carefully. Mixing in smaller quantities and working in a cooler environment can extend usable working time on larger assemblies, while keeping mixed mass under 4 kg avoids the risk of premature heat-driven cure inside the container.
Why Consistent Sourcing Matters
Composite fabricators and assemblers who use this adhesive across multiple production runs benefit from consistent resin and hardener viscosity batch to batch. Variation in these properties can affect mix ratio accuracy and working time, which is why buyers sourcing LOCTITE EA 9497 for repeat use should confirm supply continuity with their supplier before committing to large orders.

FAQ: LOCTITE EA 9497
What is LOCTITE EA 9497 used for?
It is used as a two-part structural epoxy adhesive for high-strength bonding applications.
What is the working life after mixing?
The mixed adhesive has a working life of 3 to 4 hours at 22 °C, shorter at higher temperatures or with larger batches.
Is there a maximum mixed batch size?
Yes, quantities greater than 4 kg should not be mixed, as excessive heat build-up can occur.
How is excess adhesive removed?
Uncured excess can be wiped away with an organic solvent such as acetone; equipment should be cleaned with hot soapy water before the adhesive hardens.
