MR. JO JH 1056: The Low Viscosity Polyamide Hardener for High-Performance Systems
What is JH 1056?
JH 1056 is a low viscosity polyamide curing agent that pairs effectively with liquid epoxy resins like JR 3013 and JR 3000.
Its standout feature is its exceptional flowability, making it the perfect choice for potting, encapsulation, mortars, and adhesives requiring high filler loading.
Key Technical Highlights
- Amine Value: 350–400 mg KOH/g
- Viscosity (25°C): 500–1,000 mPa·s
- Color (Gardner): ≤10
- Density (25°C): 0.98–1.01 g/cc
This low-viscosity profile ensures easy processing, excellent penetration, and compatibility with high filler systems.

Why Choose JH 1056?
- ✅ Low Viscosity – Ensures excellent wetting, spreading, and penetration into substrates.
- ✅ High Filler Loading – Enables mortars, adhesives, and filled systems without compromising performance.
- ✅ Versatile – Suitable for electrical, construction, and industrial applications.
- ✅ Strong Adhesion – Delivers long-term durability and bond strength across surfaces.

Applications at a Glance
- Potting & Encapsulation → Electrical and electronic applications where flow and coverage are critical.
- High Filler Adhesives → Mortars and construction systems requiring bulk filler incorporation.
- Mortars & Grouts → Structural repairs with high durability.
- Industrial Coatings → Reliable performance for tough environments.
Features that Stand Out - Very low viscosity for effortless application
- High filler loading capacity
- Excellent substrate wetting
- Solvent-free formulation
- Strong, durable adhesion
For projects demanding easy processing, excellent wetting, and the ability to incorporate high filler content, JH 1056 is the ideal polyamide hardener. Whether used in electrical encapsulation or high-performance construction mortars, it ensures reliable strength and durability.
