Description

Jpoxy JR 3390 is a special liquid that sticks things together. It comes from a material called Bisphenol-F and mixes easily. People use it for many different jobs because it works well in various projects. When you combine it with other materials, it makes things strong and long-lasting. You can use it to fix, build, or create products that need to stay together really well.

Q1. What is JR 3390?

A1. JR 3390 is a general-purpose, unmodified Bisphenol-F (BPF) epoxy resin. It offers lower viscosity than standard BPA resins and is well-suited for adhesives, laminates, coatings, and civil applications where better reactivity and handling are needed.

Q2. What are the key technical specifications of JR 3390?

A2. 

  • Epoxy Equivalent Weight (EEW): 165–185 g/eq
  • Viscosity @ 25°C: 2,050–5,050 mPa·s
  • Color (Gardner): ≤3
  • Density @ 25°C: 1.15–1.20 g/cc
  • Appearance: Clear to light amber liquid
Q3. Why choose a BPF resin over a BPA resin?

A3. BPF resins offer:

  • Lower viscosity at similar EEW, enabling better filler/pigment loading
  • Higher reactivity, especially with amine curing agents
  • Improved chemical resistance and mechanical performance in some systems
Q4. What applications is JR 3390 ideal for?

A4. JR 3390 is used in:

  • High-performance structural adhesives
  • Electrical and thermal laminates
  • Protective and industrial epoxy coatings
  • Civil engineering applications like anchor grouts and repair mortars
Q5. Which hardeners work with JR 3390?

A5. It can be cured with:

  • Polyamines
  • Polyamidoamines
  • Cycloaliphatic amines, depending on the application requirements
Q6. Can JR 3390 be blended with other resins or modifiers?

A6. Yes, it can be blended with:

  • Standard BPA-based resins (like JR 3000) to balance reactivity and viscosity
  • Reactive diluents or flexibilizers for tailored performance
Q7. Is JR 3390 solvent-free?

A7. Yes, JR 3390 is a 100% solids, solvent-free epoxy resin with low VOC emissions—ideal for formulations that require environmental compliance.

Q8. What is the shelf life of JR 3390?

A8. Shelf life is 12 months from the date of manufacture when stored in tightly sealed original containers at room temperature.

Q9. What packaging sizes are available?

A9. Standard packs include 5 kg, 10 kg, and 20 kg options. Bulk packaging is available on request.
