Product Description
Permabond ET522 B is the hardener component of the 2K epoxy system ET522 — it is used in conjunction with ET522 component A for complete bonding.
This single pack contains only the hardener component (B) of the 2K epoxy ET522. The corresponding resin component (A) is available separately as Permabond ET522 A.
Permabond ET522 Component B — Single pack of hardener. Used in conjunction with ET522 Component A (resin) to form a complete 2K epoxy system.

Frequently asked questions about Permabond ET522 B
Practical application and design questions — answered by SILITECH.
Permabond ET522 B is a single component of a 2K epoxy system — see category for the corresponding counter-component. Permabond ET522 Component B (Hardener) — single pack of the 2K epoxy system.
No. Two-component epoxies only harden when the resin (A) and hardener (B) are mixed in the correct ratio. A single component remains liquid and does not harden.
When consumption levels are unequal, a component needs to be replaced, or there is a specific procurement requirement, the complete system is usually recommended.
The mixing ratio is specified in the technical data sheet of the master system. Please consult the master TDS or contact SILITECH before processing.
Store at 5 to 25 °C in the original, unopened packaging. Protect hardener components especially from moisture.
