MR. JO JH 1029: Isophorone Diamine (IPDA) – The Choice for UV-Resistant, Tough & Durable Epoxy Systems
When epoxy systems are exposed to sunlight, outdoor weather, or demanding structural conditions, formulators need a curing agent that delivers UV resistance, toughness, and long-term durability. That’s where JH 1029 (Isophorone Diamine / IPDA) stands out.
Key Technical Data
- Chemical Type: Isophorone Diamine (cycloaliphatic amine)
- Amine Value (mg KOH/g): 625 – 665
- Viscosity @ 25°C (mPa·s): 18 – 23
- Color (Gardner): ≤1 (very low color)
- Density @ 25°C (g/cc): 0.85 – 0.98
This cycloaliphatic diamine brings superior color stability and UV resistance compared to traditional aliphatic and polyetheramines.
Why Choose JH 1029?
✔ Excellent UV resistance – prevents yellowing, ideal for outdoor & clear systems.
✔ High mechanical strength & toughness – suitable for structural applications.
✔ Moderate reactivity – longer pot life than fast-curing aliphatic amines.
✔ Low viscosity, low color – makes it easy to handle and suitable for aesthetic coatings.
✔ Good chemical & moisture resistance – trusted in harsh environments.
Typical Applications
- UV-resistant clear coatings & floor sealers
- Marine & protective coatings exposed to sun and salt
- Structural adhesives & composites needing toughness and durability
- Electrical encapsulation & potting with color stability
- Civil engineering – flooring, injection, repair systems
Formulation Advantages - Compatible with standard bisphenol-A and bisphenol-F epoxy resins.
- Can be blended with polyetheramines (like JH 1035) for toughness and flexibility.
- Blends well with accelerators (BDMA, AEP, etc.) to adjust cure speed.
- Provides a superior alternative to aromatic amines when UV stability is required.
Why JH 1029?
Global leaders like Evonik, Huntsman, and Wanhua produce IPDA, but availability is often restricted to bulk. JH 1029 makes this specialty amine available in both industrial and small-pack supply formats, giving formulators and innovators easier access.
