Using this specific product
Loctite (Henkel) EA 3430 Epoxy Adhesive is listed here as the Two-part, German data sheet version for two-part epoxy, 5 minute epoxy, and bonding. For mixing and curing epoxy, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Two-part, German data sheet; related versions can use different timing.
- For two-part epoxy, 5 minute epoxy, and bonding, pay particular attention to mix ratio, batch size, temperature and pour thickness.
- At 22°C (72°F). No temperature is given for this value.
How to check readiness
Check the coolest or thickest part for firmness before sanding, demolding or loading. The data sheet gives a working time of 4 minutes or less for the mixed adhesive. Lift or move the item gently and avoid twisting the bond or pressing finished faces together. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.
Avoid this mistake
A larger batch can heat faster while a thin film may cure more slowly.
