MR. JO JR 3016: Modified Epoxy Resin for Adhesives, Topcoats & Flooring
Introduction
Formulators striving for high performance in adhesives, flooring, or clear topcoats often face compromises: either add diluents or reactive modifiers after purchase (which introduces variability), or settle for a resin that’s simply too viscous. JR 3016 is engineered to remove this compromise. A bisphenol-A epoxy resin modified with a mono-functional aliphatic reactive diluent, it offers viscosity reduction built-in while preserving epoxy backbone strength. With EEW = 190-200 g/eq and viscosity = 550-800 mPa·s at 25 °C, JR 3016 sits in the medium-low viscosity band — just enough body for handling, yet easy flow for coatings and adhesives.
Comparable in flow/handling to known global grades in the modified aliphatic epoxy space, JR 3016 offers formulators a reliable, locally available choice.
Technical & Performance Highlights
- Modified Resin: Mono-functional aliphatic reactive diluent integrated into BPA epoxy resin.
- EEW: 190-200 g/eq — gives a reactive baseline that supports many hardeners.
- Viscosity @ 25 °C: 550-800 mPa·s — significantly more fluid than fully unmodified resins yet retaining enough body for bead retention in adhesives.
- Color: Gardner ≤ 0.5 — useful for topcoats and clear finishes.
- Density: ~1.00-1.10 g/cc at 25 °C — in line with standard epoxy modified variants.
Why JR 3016 Brings Value
- Easier Processing, Less Diluent Needed
With its medium-low viscosity, JR 3016 reduces or eliminates the need for external reactive diluent or thinning in many adhesive or coating formulations. - Balanced Flow & Hold
The resin has enough viscosity to maintain body (less sagging when applied vertically or with thicker films), while still achieving good wetting and pigment dispersion. - Broad Hardener Compatibility
Works well with common curing agents: amines, polyamides, cycloaliphatic amines. Formulator latitude to target pot life, adhesion, flexibility, or hardness depending on application. - Performance in Final Film
Provides good adhesion, durability and wear resistance in flooring systems; in topcoats, gives smooth finish with gloss retention; adhesives maintain strength with better workability.
Applications
- Adhesives
Especially useful when adhesive-beads need to stay in place yet the resin must flow into surface irregularities. Ideal for bonding concrete, wood, tiles, and metal substrates. - Topcoats & Clear Coatings
In architectural or industrial settings where visual gloss, clarity, and color stability matter — JR 3016 gives a clean base that responds well to pigmentation or transparency. - Flooring Systems
Especially in self-leveling or light traffic industrial floors, where formulation demands both flow and enough body to resist sagging.
Near-Equivalent Commercial References
While every resin system has unique behavior, JR 3016’s viscosity, EEW, and flow/hold balance make it similar in handling to modified aliphatic epoxy resins used globally. Formulators working with analogous grades (e.g. low-visc aliphatic epoxies from large suppliers) will find JR 3016 a viable alternative with local supply advantages.
Formulation & Processing Notes
- Use fillers or pigmentation as needed — JR 3016’s viscosity allows for good dispersion without over-shearing.
- For adhesive applications, substrate preparation (clean, dry, primed if needed) improves bond reliability.
- Cure schedule should be matched to desired performance: fast amine cures for speed, slower hardeners or elevated post-cure for improved chemical or thermal resistance.
- For flooring or topcoats, ensure film thickness is controlled; thicker layers may require longer cure times or staged application to avoid blush or incomplete cure.
Conclusion
JR-3016 delivers a compelling mix: low-to-medium viscosity, modified resin convenience, and performance nearer to what you expect from higher solids or mid-viscosity resins.
If your next project needs adhesives that flow well into gaps, topcoats that level nicely, or flooring layers that combine fluidity with durability, JR-3016 is an excellent resin backbone to build from.
