A Formulator’s Guide to Modified Epoxy Resins: JPOXY JR Series
Choosing the right epoxy resin is one of the most important formulation decisions for adhesives, coatings, flooring, and composite systems. Different projects demand different rheology, chemical resistance, cure profiles, and handling properties. JPOXY’s Modified Epoxy Resins (JR Series) are designed to give formulators a wide toolbox of viscosity ranges, reactive diluent chemistries, and performance balances.
This guide helps you select the most suitable resin for your application — from high-viscosity resins for bead-hold and waterproofing, to ultra-low-viscosity grades for casting, priming, or self-levelling flooring.
Why choose modified epoxy resins?
- Lower viscosity, easier processing – without adding excessive non-reactive solvents or diluents.
- Improved workability – better flow, wetting, and degassing depending on grade.
- Tailored cured properties – different diluent chemistries (aliphatic vs. aromatic, mono vs. di-functional) influence final hardness, chemical resistance, and weatherability.
- Application-specific performance – each grade is optimized for real-world end uses: coatings, adhesives, self-levelling floors, composites, potting, grouts, and more.
How to choose the right grade
- Start with viscosity & flow
- High viscosity (JR 3011, JR 5124) → bead/hold, waterproofing, thick film coatings.
- Mid-range viscosity (JR 3012, JR 5126, JR 4125, JR 3018) → balanced flow, good for coatings, floorings, adhesives.
- Low viscosity (JR 3016, JR 3017, JR 3013) → maximum flow, best for primers, self-levelling, potting, and grouts.
- Match chemistry to performance
- Aliphatic mono-functional → better outdoor weathering, clarity, gloss.
- Aromatic mono-functional → higher chemical resistance and hardness.
- Aliphatic di-functional → higher crosslink density, good for composites and RTM.
- Check application suitability
- Flooring & mortars → JR 3005L, JR 3012, JR 3017.
- Adhesives → JR 3016, JR 3017, JR 3005L.
- Chemical-resistant coatings → JR 3018, JR 3011.
- Composites & filament winding → JR 5126.
- Primers & thin coatings → JR 3013, JR 3016.
- Casting & potting → JR 4125, JR 5857.
Benefits for formulators
- Simplified selection – one series covers a wide range of EEWs and viscosities.
- Compatibility – works with standard curing agents (polyamines, amidoamines, cycloaliphatic, polyamides, etc.).
- Proven performance – comparable to leading global brands (Aditya Birla, Huntsman, Spolchemie, Araldite) while being cost-efficient and locally available.
- Flexibility – choose the grade that minimizes the need for extra diluents while achieving the desired performance balance.
Conclusion
The JPOXY JR Series Modified Epoxy Resins give formulators the flexibility to design smarter, stronger, and more efficient systems. Whether you’re working on self-levelling floors, structural adhesives, composites, or chemical-resistant coatings, the selector guide helps you identify the right grade with confidence.
