MR. JO JR 3017: Aromatic Reactive Diluent Modified Epoxy Resin
Introduction
When formulating high-performance adhesives, self-leveling floors, grouts, or mortars, the biggest challenge is balancing workability with strength and chemical resistance. Standard bisphenol-A resins often need external diluents to reduce viscosity, but these can compromise toughness, adhesion, or resistance.
JPOXY JR 3017 is designed to solve this challenge. It is a bisphenol-A epoxy resin modified with a mono-functional aromatic reactive diluent, combining easy flow with enhanced mechanical and chemical properties. With EEW 180–190 g/eq and viscosity 500–700 mPa·s @ 25 °C, it is close in profile to benchmark grades like Aditya Birla YD128 and Araldite GY257 — making it a trusted local alternative for critical civil and industrial applications.
Technical & Performance Highlights
- Resin Type: BPA epoxy resin pre-modified with mono-functional aromatic reactive diluent.
- EEW: 180–190 g/eq — slightly lower than aliphatic-modified variants, increasing crosslink density.
- Viscosity @ 25 °C: 500–700 mPa·s — easy to handle, pump, mix, and apply.
- Color: Gardner ≤ 1 — sufficiently light for pigmented flooring, adhesives, and mortars.
- Density: 1.00–1.10 g/cc — in line with standard liquid epoxy resins.
Why Choose JR 3017
- Superior Chemical & Mechanical Performance
The aromatic reactive diluent contributes to higher glass transition temperature (Tg), hardness, and chemical resistance compared to aliphatic diluent-modified systems like JR 3016. - Optimized Flow Without Excess Diluents
Its built-in viscosity reduction allows better filler wetting and easier application in flooring and grout formulations without relying heavily on external diluents. - Proven Equivalency
Formulators familiar with YD128 or GY257 will find JR 3017 to be a drop-in equivalent for most civil and adhesive systems, with the advantage of local availability and supply reliability. - Broad Hardener Compatibility
Cures with a wide range of curing agents (polyamides, amines, cycloaliphatics, modified amines), allowing tailored pot life and cure profiles.
Application Areas
- Self-Leveling Flooring
Smooth flow and filler-wetting make JR 3017 excellent for industrial and commercial epoxy floor systems. Offers hardness and abrasion resistance needed in high-traffic areas. - Adhesives
Provides balanced viscosity for handling and strong adhesive bonds for concrete, metals, wood, and composites. - Civil Engineering Applications
Ideal for grouts, repair mortars, anchoring compounds, and structural bonding where load-bearing and chemical resistance are critical. - Epoxy Mortars & Grouts
Its ability to wet fillers like quartz, silica, and cementitious powders ensures homogeneous, strong, and durable composites.
Processing & Formulation Notes
- Use JR 3017 where higher chemical resistance and strength are required compared to aliphatic-modified resins (like JR 3016).
- For flooring & mortar formulations, add graded fillers for mechanical strength; JR 3017 provides sufficient flow to ensure good compaction.
- For civil/structural grouts, pair with polyamide or cycloaliphatic curing agents for balance of pot life, strength, and reduced exotherm.
- Compatible with pigments, quartz powders, and silica sands commonly used in flooring and repair systems.
Conclusion
JR 3017 is a versatile, aromatic reactive diluent-modified epoxy resin offering the sweet spot of easy processing and superior performance. It bridges the gap between fluid handling and structural strength, making it ideal for floorings, adhesives, mortars, and civil repair systems.
For formulators who have relied on YD128 or GY257, JR 3017 provides a reliable, locally supplied equivalent with strong application support.
