MR. JO JH 8361 – Heavy-Duty Phenalkamine Hardener for Marine & Protective Coatings
MR. JO JH 8361 – Heavy-Duty Phenalkamine Hardener for Marine & Protective Coatings
When it comes to epoxy curing in real-world conditions, very few hardeners can match the performance of phenalkamines. JH 8361 is our high-performance phenalkamine curing agent, specially designed for marine coatings, heavy-duty floorings, and protective applications where humidity, moisture, and salt contamination are everyday challenges.
🔎 What is JH 8361?
- Type: Phenalkamine curing agent (CNSL-based)
- Comparable to: Cardolite NC541
- Amine Value: 300–335 mg KOH/g
- Viscosity @25°C: 25,000–50,000 mPa·s
- Color (Gardner): ≤17
- Density: 0.97–1.00 g/cc
- Recommended PHR: 50–55 (with standard epoxy resins)
This grade is high viscosity, multifunctional, and delivers excellent adhesion, saltwater resistance, and corrosion protection.
⚙️ Key Features
- Outstanding chemical & corrosion resistance – perfect for marine, industrial, and offshore use.
- Moisture tolerance – cures reliably in humid and damp conditions.
- Excellent adhesion – strong bonding to steel, concrete, and coated substrates.
- Ambient curing – suitable for room temperature applications, with the option of post-curing for enhanced properties.
📌 Applications
- Marine coatings – ship hulls, cargo holds, ballast tanks.
- Protective coatings – pipelines, storage tanks, structural steel.
- Industrial flooring – chemical-resistant floors in process plants.
- Concrete protection – old-to-new bonding and civil repair coatings.
🚀 Mr. JO Advantage – Project-Ready Packs
While phenalkamines like NC541 are widely used, they are mostly supplied in large bulk packs — not always convenient for contractors, applicators, or small OEMs.
👉 JH 8361 solves this gap. We supply consistent-quality phenalkamine hardeners in user-friendly, project-sized packs, making it easier for:
- Contractors working across multiple sites.
- Applicators who need controlled batch sizes.
- SMEs and R&D labs exploring new epoxy systems.
This flexibility ensures you get the performance of global benchmarks with the practicality of project-ready solutions.
🎯 Why Choose JH 8361?
- Comparable to global benchmark Cardolite NC541.
- Strong corrosion & saltwater resistance.
- Reliable ambient cure in humid conditions.
- Available in easy-to-handle packs – a unique MR. JO advantage.
