MR. JO JR 3012: Modified Epoxy Resin for Coatings, Primers, Mortars, and Flooring
Introduction
As industries continue shifting toward high-solids, solvent-free, and environmentally compliant epoxy systems, formulators need liquid resins that offer both low viscosity and high versatility. Unmodified bisphenol-A (BPA) resins deliver excellent adhesion and durability, but their viscosity often limits solids loading and ease of processing.
JR 3012 has been developed to solve this challenge. It is a bisphenol-A epoxy resin modified with a mono-functional aliphatic reactive diluent, designed to combine the performance of BPA epoxy resins with the ease of processing of a built-in viscosity modifier. With an EEW of 185–210 g/eq and a viscosity of 1200–1800 mPa·s at 25 °C, JR 3012 is a low-to-medium viscosity resin that enables smooth formulation of coatings, primers, mortars, and flooring systems.
Comparable to Aditya Birla’s YD 510, JR 3012 is positioned as a dependable, drop-in alternative for global formulators who seek both cost efficiency and performance consistency.
Key Technical Features
- Modified resin: BPA epoxy resin pre-modified with mono-functional aliphatic reactive diluent.
- Viscosity: 1200–1800 mPa·s @ 25 °C, significantly lower than conventional unmodified resins.
- Epoxy Equivalent Weight (EEW): 185–210 g/eq, compatible with a wide range of curing agents.
- Color: Gardner ≤0.5, ensuring high clarity and excellent acceptance of pigments/fillers.
- Density: 1.10–1.15 g/cc @ 25 °C, offering stable processing.
Why Choose JR 3012?
- Low Viscosity for High-Solids Systems
JR 3012’s viscosity profile makes it ideal for formulating high-solids coatings and solvent-free systems without compromising on mechanical strength or adhesion. - Improved Handling and Flow
Its pre-integrated reactive diluent reduces mixing complexity and ensures consistent wetting, spreading, and film formation. - Wide Hardener Compatibility
Works well with polyamines, polyamides, cycloaliphatic amines, and anhydrides, giving formulators flexibility to design systems for coatings, flooring, or construction. - Enhanced Workability in Mortars & Flooring
The lower viscosity aids in filler incorporation, making JR 3012 especially suited for epoxy mortars, screeds, and self-leveling flooring systems where ease of mixing and placement are critical.
Applications
1. High-Solids Coatings
o Used in protective and industrial coatings requiring low-VOC, high-build systems.
o Provides excellent wetting and flow, ensuring uniform film thickness.
2. Primers
o JR 3012’s viscosity and surface wetting properties make it ideal for epoxy primers on concrete, metal, or composites.
o Improves adhesion and promotes long-term durability of subsequent layers.
3. Epoxy Mortars & Screeds
o Excellent for filled systems, where ease of incorporation of sand, quartz, or silica flour is essential.
o Produces durable, chemical-resistant mortars for industrial flooring and repair systems.
4.Flooring Systems
o Suitable as a base resin for self-leveling and trowel-applied flooring systems.
o Offers smooth finish, durability, and compatibility with epoxy-compatible pigments.
Commercial Equivalents
JR 3012 is similar to Aditya Birla YD 510, enabling formulators to benchmark performance against a widely recognized global resin. This makes substitution or parallel adoption straightforward for formulators working across regional supply chains.
Processing and Formulation Notes
- Compatible with common epoxy-compatible fillers and pigments.
- For flooring and mortar systems, filler loadings of 4–8x liquid volume are typical, depending on application.
- Systems should be designed with appropriate curing agents to optimize flexibility, hardness, or chemical resistance depending on end-use.
- Post-curing is recommended where higher Tg or chemical resistance is required.
Conclusion
JR 3012 provides a practical solution for formulators seeking a low-viscosity, high-performance epoxy resin for coatings, primers, mortars, and flooring. By integrating a mono-functional aliphatic reactive diluent, it eliminates the need for external viscosity adjustments, simplifying formulation and ensuring consistent performance.
For industries demanding efficiency, workability, and performance in a single package, JR 3012 stands as a reliable choice — delivering the strength of epoxy resins with the processability of a modified system.
