🏭 Application Areas
| Sector | Description |
|---|---|
| Latex Products | Provides ultra-fast curing in gloves, balloons, condoms, etc. |
| Natural Rubber | Acts as a secondary accelerator for low-temperature vulcanization. |
| Synthetic Rubber | Supports curing in SBR, NBR, EPDM systems. |
| Medical Products | Preferred in medical-grade rubber due to nitrosamine-free profile. |
| Adhesives | Used in specialized “Medicine Glue” formulations. |
✅ Advantages
-
⚡ Ultra-fast curing: Highly efficient in dipping and latex systems.
-
🧼 Clean formulation: Nitrosamine-free, suitable for medical and hygiene applications.
-
🧪 High dispersion: Ensures homogeneous mixing in PD form.
-
📉 High efficiency at low dosage: Effective as a secondary accelerator.
⚠️ Precautions
-
May cause scorching (early vulcanization) — process control is critical.
-
Can degrade at high temperatures — stability testing is advised.
-
May react with metal ions — formulation compatibility should be verified.
