MR. JO JH 1037: Diethylenetriamine (DETA) – The Fast-Curing Workhorse for Epoxy Systems
When formulators need very fast cure, strong adhesion, and reliable chemical resistance, Diethylenetriamine (DETA) is often the first choice. JH-1037 brings this standard curing agent to you in reliable quality and flexible pack sizes, making it accessible for both industrial scale and smaller, specialized projects.
Key Technical Data
- Chemical Type: Diethylenetriamine (linear aliphatic amine)
- Amine Value (mg KOH/g): 1,500 – 1,659
- Viscosity @ 25°C (mPa·s): 5 – 15
- Color (Gardner): ≤2
- Density @ 25°C (g/cc): 0.95 – 0.98
With three amine groups and five reactive hydrogens, DETA is highly reactive, delivering rapid crosslinking and excellent adhesion properties.
Why Choose JH 1037?
✔ Fast ambient curing – significantly reduces working time, ideal for quick applications.
✔ Excellent adhesion – bonds well to concrete, metals, and composites.
✔ Good chemical resistance – suitable for aggressive environments.
✔ Low viscosity – easy handling and mixing with standard liquid resins.
✔ Proven versatility – works across coatings, adhesives, and construction systems.
Typical Applications
- Primers & seal coats that need fast recoat times
- Adhesives & repair pastes where quick strength development is critical
- Protective coatings for metal and marine use
- Civil engineering systems – grouts, mortars, and injection resins
- Electrical encapsulation – when quick set is an advantage
Formulation Insights - Reacts faster than TETA (JHc1036), making it suitable when speed > pot life.
- Can be blended with slower amines (like IPDA or polyamides) to balance working time.
- Accelerators (e.g., AEP – JH 1063) can further fine-tune gel time.
Why JH 1037?
Global majors like Huntsman, BASF, Wanhua, and Evonik supply DETA — but typically in bulk drums only, leaving small users underserved. JH 1037 ensures that even R&D labs, startups, and niche manufacturers can access authentic, consistent DETA in smaller packs, with dependable availability through JPOXY’s distribution.
