PERMABOND ET5428 black
PERMABOND ET5428 black
Permabond · Permabond Engineering Adhesives Ltd ·

Permabond ET5428 black is the strongest variant in the ET series — up to 34 N/mm² steel shear strength combined with black curing and fast pot life.

With 28–34 N/mm² steel shear strength, ET5428 black is the strongest variant in the Permabond ET series — the premium choice for the most demanding structural bonding applications. The black cure makes the product visually unobtrusive on dark substrates.

PREMIUM STRENGTH

Highest steel shear strength of the ET series (28–34 N/mm²) in black curing — the premium choice for high-load structural bonding with aesthetic requirements or dark substrates.

Processing

1
Clean surfaces
Bonding surfaces must be clean, dry, and free of grease. Degrease with Permabond Cleaner A or a solvent (acetone, isopropanol). Lightly sand aluminum and copper to remove oxide layers.
2
Mix components A + B
For twin cartridges: attach the mixing nozzle and press evenly (2:1 volume ratio mixing ratio). For larger containers: weigh resin and hardener in the correct ratio and mix thoroughly until no streaks are visible. Avoid air entrapment.
3
Apply adhesive + join components
Apply the mixed adhesive to a bonding surface within the pot life (10–20 minutes @ 23 °C). Join components with sufficient pressure to ensure the adhesive spreads over the entire bonding surface.
4
Fix components during curing
Use a clamping device or clamp to ensure the components do not move during curing. Wait for handling strength and functional strength according to the TDS.
5
Full cure at room temperature
Final strength is typically achieved after 24 hours at 23 °C. Increasing the temperature by 8 °C halves the curing time; lower temperatures slow down the process. If necessary, optionally post-cure at 60–80 °C for maximum strength.

Important Notes

Important Notes
Before bonding, degrease surfaces and sand if necessary. For aluminum/copper, remove the oxide layer.
Storage
Store at 5 to 25 °C. Keep 2K epoxy components in closed packaging — especially protect the hardener from moisture.

Frequently asked questions about Permabond ET5428 black

Practical application and design questions — answered by SILITECH.

Black high-strength structural adhesive 2:1 — up to 34 N/mm² steel, fast pot life. The 2K epoxy is mixed in a 2:1 volume ratio and offers a pot life of 10–20 minutes @ 23 °C.

Mix both components in a 2:1 ratio by volume — for double cartridges use a mixing nozzle, for larger containers weigh out precisely. Apply within the pot life (10–20 minutes @ 23 °C) and join the parts together. Full curing typically occurs after — at room temperature.

The pot life of Permabond ET5428 black is typically 10–20 minutes @ 23 °C at 23 °C. Higher temperatures shorten, lower temperatures extend the pot life. Mixing quantities above approximately 100 g can cure faster due to exothermic reaction.

Permabond ET5428 black bonds reliably: Steel: 28–34 N/mm². For thermoplastic substrates, check compatibility before series use.

Permabond ET5428 black has no specific industry-specific approvals such as EU 10/2011 (food contact), UL94 (flame retardancy), or Boeing/Airbus (aerospace). For general industrial applications, the product is approved according to Permabond standards.

Permabond ET5428 black is a black high-strength structural adhesive 2:1 — peak shear strength (28–34 N/mm²) (2:1 by volume mix, 10–20 minutes @ 23 °C pot life). Permabond ET5429 is high-strength 2:1 (2:1, — pot life) — lower strength.

From the Permabond 2K epoxy series, select according to application, mixing ratio, and strength requirements: Permabond ET5428 black (black high-strength structural adhesive 2:1 — peak shear strength); Permabond ET5429 (high strength 2:1); Permabond ET5401 (fast 2:1); Permabond ET536 (high strength 1:1). For aerospace, see ET515 (Aircraft Seat Trays); for food contact, ET5162 (EU 10/2011 + FDA); for thermal conductivity/fire protection, ET5441 (UL94-V0).
