MR. JO JH 1059 – Fast-Setting, Moisture-Tolerant Hardener for Repairs & Construction
In the world of construction and repair, time is money. Delays caused by long curing times or poor performance in damp conditions can derail projects and increase costs. That’s why professionals need a hardener that not only cures quickly but also stands strong in real-world jobsite conditions.
Enter JH 1059 – a fast-setting, high-reactivity epoxy hardener designed for quick, durable fixes.
What is JH 1059?
JH1059 is a modified aliphatic polyamine curing agent that works at a low mix ratio (18 PHR), making it highly efficient in formulations. Its low viscosity (100–250 mPa·s at 25°C) allows easy mixing and excellent penetration into cracks and voids, while its fast reactivity ensures repairs set quickly, reducing downtime.
- Mix Ratio: 18 PHR with standard epoxy resins
- Amine Value: 650–750 mg KOH/g
- Viscosity (25°C): 100–250 mPa·s
- Color (Gardner): ≤7
- Density (25°C): 1.00–1.05 g/cc
Why Choose JH 1059?
- Fast Setting – Short working and curing times make it ideal for urgent repairs.
- High Reactivity – Ensures strong chemical bonding and mechanical strength.
- Moisture Tolerance – Works reliably even in damp or wet substrates.
- Low Viscosity – Provides excellent penetration for injection grouting and fine crack repair.
- High Mechanical Strength – Guarantees durability for structural repairs.
Applications of JH 1059
- Construction Adhesives – Fast bonding for precast or on-site components.
- Injection Grouting – Low-viscosity flow for filling cracks and voids.
- Repair Mortars – Quick-setting formulations for emergency or time-sensitive repairs.
- Quick-Setting Floor & Wall Repairs – When downtime must be minimized.
