MR. JO JH 1035: Polyetheramine Hardener for Flexible, Clear & High-Performance Epoxy Systems
MR. JO JH 1035: Polyetheramine Hardener for Flexible, Clear & High-Performance Epoxy Systems
When strength must combine with flexibility, clarity, and toughness, formulators turn to Polyetheramines. JH 1035 is a polyetheramine (D230 equivalent) that offers outstanding toughness, flexibility, and moisture resistance while retaining compatibility with a wide range of epoxy resins.
Key Technical Data
- Chemical Type: Polyetheramine (mono-propylene oxide backbone)
- Amine Value (mg KOH/g): 440 – 490
- Viscosity @ 25°C (mPa·s): 10 – 15 (low, easy handling)
- Color (Gardner): ≤1 (water-clear)
- Density @ 25°C (g/cc): 0.95 – 1.00
Why Choose JH 1035?
✔ Exceptional toughness & flexibility – reduces brittleness in epoxy systems.
✔ Excellent clarity – ideal for clear coatings, art resins, and casting systems.
✔ Moisture & chemical resistance – reliable in coatings, adhesives, and composites.
✔ Low viscosity – easy mixing, excellent filler wetting, and smooth self-leveling.
✔ Balanced reactivity – moderate cure speed suitable for a wide range of applications.
Typical Applications
- Clear casting & art resins – bubble-free clarity and glass-like finish.
- Flooring topcoats & sealers – impact and abrasion resistance with flexibility.
- Adhesives – structural, flexible bonding in composites and construction.
- Civil & industrial repair systems – epoxy mortars and repair pastes with toughness.
- Composites & wind energy – enhanced toughness and fatigue resistance.
This is a clear, low-color hardener designed for premium applications that demand high mechanical properties and aesthetic performance.
Formulation Advantages
- Used at ~32 PHR with standard epoxy resins (EEW ~190).
- Can be blended with cycloaliphatic or aliphatic amines to adjust cure speed and hardness.
- Compatible with diluents and modifiers for viscosity control.
- Improves impact resistance, elongation, and crack-bridging properties.
Why JH 1035?
MR. JO makes polyetheramine chemistry accessible, offering it not only in industrial bulk but also in small, lab-friendly packs — a rarity in the market. Whether you are a flooring formulator, composite manufacturer, or art resin innovator, JH 1035 ensures consistency, quality, and support.
