MR. JO JR 3005L: Low-Viscosity Modified Epoxy Resin for Flowable Systems
Introduction
When it comes to self-levelling floorings, flowable mortars, and construction adhesives, formulators face the constant challenge of achieving the right balance between workability and performance. Standard bisphenol-A epoxy resins are often too viscous for these applications, requiring external reactive diluents to improve flow. However, relying on external diluents can compromise mechanical strength, chemical resistance, or cure uniformity.
JR 3005L solves this problem by incorporating a mono-functional aliphatic reactive diluent modification directly into the epoxy backbone. The result is a pre-modified epoxy resin that offers a viscosity of just 750–900 mPa·s at 25 °C, while maintaining excellent curing characteristics and mechanical properties. It is a strong equivalent to Aditya Birla YD515, making it a dependable choice for industrial users seeking performance and consistency.
Technical Profileut – CMR
- Resin Type: Bisphenol-A epoxy resin modified with mono-functional aliphatic reactive diluent
- EEW (g/eq): 190–210
- Viscosity @ 25 °C: 750–900 mPa·s — exceptionally low for an epoxy resin, ideal for self-levelling systems
- Color (Gardner): ≤ 0.5 — ensures compatibility with clear or pigmented systems
- Density @ 25 °C: 0.95–1.05 g/cc
Key Advantages
- Excellent Flowability
Built-in diluent modification significantly reduces viscosity, making JR 3005L ideal for pourable, self-levelling, and pumpable systems. - Reduced Reliance on External Diluents
Since the resin already offers low viscosity, formulators can minimize or avoid additional reactive diluents, preserving mechanical and chemical resistance. - Balanced Mechanical Strength
Unlike over-diluted systems, JR 3005L maintains reliable compressive, flexural, and adhesive strength, making it suitable for demanding flooring and construction applications. - Industrial Equivalency
Performance closely matches YD515, but with the benefit of local availability and technical support, reducing supply chain risks.
- Self-Levelling Floorings
JR 3005L is ideal for 1–3 mm SL systems, offering easy application, smooth flow, and excellent surface finish without sacrificing hardness. - Adhesives
The low viscosity ensures excellent substrate wetting and penetration, which improves bond strength in construction and repair adhesives. - Construction Chemicals
Used in primers, repair systems, and injection grouts where flow and penetration are critical. - Flowable Mortars & Grouts
Ensures smooth dispersion of fillers, aggregates, and pigments, while maintaining cohesive, non-brittle cured films.
Processing & Formulation Notes - Curing Agents: Works well with polyamines, cycloaliphatic amines, and polyamide hardeners, depending on the end-use (fast set vs. long pot life).
- Fillers & Aggregates: Compatible with silica, quartz, and graded sand systems for mortars and flooring screeds.
- Pigments & Additives: Accepts inorganic pigments and disperses uniformly, thanks to its low viscosity profile.
- VOC Compliance: Supports formulation of high-solid, low-VOC systems without compromising handling.
Conclusion
JR 3005L represents a purpose-built solution for flowable, self-levelling, and adhesive applications where viscosity reduction is essential but performance cannot be sacrificed. With its inherently low viscosity, balanced cure, and industrial equivalency to YD515, it is a reliable choice for formulators in flooring, adhesives, and construction chemicals.
By using JR 3005L, manufacturers can reduce dependence on external diluents, improve formulation consistency, and deliver high-performance end products that meet the growing demands of modern construction and industrial flooring markets.
