MR. JO JH 8362 – Reliable Curing in Cold & Damp Conditions
Working on-site often means working with uncertainty — low temperatures, damp concrete, or even high humidity levels. Conventional curing agents struggle in such conditions, leading to delayed schedules and compromised performance. JH 8362 has been designed precisely to address these challenges.
What is JH 8362?
JH 8362 is a phenalkamine-based curing agent that combines excellent curing performance with tolerance to moisture and cold. When paired with standard epoxy resins, it ensures strong bonding, fast development of mechanical strength, and reliable protection — even when curing conditions are far from ideal.
Key Technical Profile
- Mix Ratio (phr): 50–60 with standard Bis-A epoxy resins
- Viscosity @ 25 °C: Medium, easy to handle at site
- Pot Life (100 g @ 25 °C): ~60 minutes – offers ample working time
- Tack Free Time: 6–8 hours (thin film)
- Shore D Hardness: 75–80 after full cure
- Adhesion: Excellent on concrete and steel, often leading to substrate failure in pull-off tests
This balance of working time and cure speed makes JH 8362 highly suitable for both coatings and repair mortars.
Where to Use JH 8362
- Marine structures – jetties, ballast tanks, splash zone repairs
- Infrastructure – bridges, pipelines, refineries, chemical plants
- Primers – damp-tolerant primers on concrete and steel
- Repair Mortars – blends easily with fillers for structural repair applications
Its natural saltwater and chemical resistance ensures long-term durability in aggressive environments.
Why Choose JH 8362?
- Cold Cure Capability – cures reliably down to 5 °C.
- Moisture Tolerant – bonds even to damp substrates.
- Strong Adhesion – ensures repair and coating integrity.
- Contractor-Friendly Packs – available in 1 kg, 5 kg, 10 kg, and 20 kg kits for project flexibility.
The Bottom Line
When the weather is unpredictable and the substrate conditions are less than perfect, JH 8362 keeps the project moving. It is trusted by engineers, applicators, and contractors for its ability to deliver strong bonds and reliable cures in real-world site conditions.
