MR. JO JR 3390 – General-Purpose BPF Epoxy Resin with Superior Resistance
Epoxy technology is diverse, but when formulators need a balanced resin offering good chemical resistance, reduced crystallization, and versatile performance across adhesives, laminates, and coatings, a Bisphenol-F (BPF) based epoxy resin becomes the go-to choice.
JR 3390 is a general-purpose, unmodified BPF epoxy resin designed to deliver consistent results in industrial, civil, and specialty applications. Its unique backbone structure provides better chemical resistance than conventional BPA resins while minimizing crystallization issues, ensuring long-term stability in storage and use.
Technical Profile
- Epoxy Equivalent Weight (EEW): 165 – 185 g/eq
- Viscosity @ 25°C: 2050 – 5050 mPa·s
- Color (Gardner): ≤ 3
- Density @ 25°C: 1.15 – 1.20 g/cc
This balance of medium EEW and moderate viscosity makes JR 3390 a versatile resin, suitable for both solvent-free and solvent-based formulations.
Key Features
- Unmodified BPF epoxy resin – clean, consistent performance.
- Excellent chemical resistance – superior resistance to solvents, acids, and alkalis compared to standard BPA resins.
- Reduced crystallization tendency – better storage stability and easier processing.
- Good mechanical strength & adhesion – reliable results across varied applications.
Applications
- JR 3390 is a workhorse resin across industries, offering flexibility in both formulation and application:
- Adhesives – strong bonding for industrial and structural applications.
- Laminates – electrical, decorative, and high-strength laminates with chemical resistance.
- Coatings – protective and decorative coatings with durability and stability.
- Civil applications – flooring, mortars, and construction chemicals requiring resistance to harsh environments.
