🏭 Application Areas
| Sector | Description |
|---|---|
| Natural Rubber | Used as a secondary accelerator for improved aging resistance. |
| Synthetic Rubber (SBR, NBR) | Supports curing in various elastomer systems. |
| Latex Products | Limited use due to moderate curing speed. |
| Medical Products | Occasionally used in nitrosamine-sensitive applications. |
| Technical Rubber | Applied in hoses, seals, and molded parts. |
✅ Advantages
-
🧼 Low nitrosamine risk: Suitable for sensitive applications.
-
🧪 Good aging resistance: Enhances durability of rubber compounds.
-
📉 Moderate curing speed: Allows controlled vulcanization.
-
🔁 Versatile use: Applicable in both natural and synthetic systems.
⚠️ Precautions
-
Slower curing speed compared to ZDEC or ZDMC — may require combination with faster accelerators.
-
Limited latex compatibility — not ideal for dipping systems.
-
Moderate dispersion — masterbatch form preferred for uniformity.
