MR. JO JR 3333 – Modified BPA Resin Optimized for Self-Leveling Epoxy Floors
When it comes to epoxy flooring, one of the biggest formulation challenges is achieving smooth flow, uniform leveling, and bubble-free finishes. Standard resins often require additional additives and careful blending to reach this performance level.
JR 3333 solves this by design. It is a low-viscosity modified BPA epoxy resin engineered with built-in rheology modification, air release, and self-leveling additives. This makes it the first-choice resin for self-leveling epoxy floor systems, offering contractors and formulators a dependable, ready-to-use solution.
Technical Profile
- Epoxy Equivalent Weight (EEW): 185 – 210 g/eq
- Viscosity @ 25°C: 800 – 1000 mPa·s
- Color (Gardner): ≤ 2
- Density @ 25°C: 1.05 – 1.15 g/cc
This balance of EEW and viscosity ensures JR 3333 provides the right flow characteristics while maintaining excellent mechanical performance after curing.
Key Features
- Built-in self-leveling properties – eliminates the need for multiple flow additives.
- Excellent air release – minimizes entrapped bubbles and pinholes in floors.
- Optimized viscosity – provides smooth application with good workability.
- High clarity, low color – enhances aesthetics of pigmented and decorative floors.
- Stable performance – reliable curing and film formation under site conditions.
Applications
- While JR 3333 can be used across coatings and construction, it is particularly recommended for:
- Self-leveling epoxy flooring – seamless, glossy, and durable floors in industrial and commercial spaces.
- Coatings – solvent-free and high-build coatings requiring smooth finish.
- Civil applications – primers and protective layers where self-leveling is advantageous.
Why JR 3333 is the First Choice for Self-Leveling Floors
- Simplifies formulation: With rheology and leveling modifiers already integrated, formulators save time and reduce complexity.
- Ensures surface quality: Contractors achieve smoother floors with fewer application defects.
- Reduces additive load: Lowers dependence on external flow/air release additives, optimizing costs and consistency.
- Trusted for flooring: Specifically tailored for SL systems, unlike standard resins that require heavy modification.
Conclusion
JR 3333 is positioned as a preferred alternative to conventional BPA resins in flooring. By combining the strength of BPA epoxy with modification for flow and leveling, it provides the perfect balance of performance, ease of use, and reliability.
For contractors, this means fewer site failures and faster installations. For formulators, this means a robust starting resin that minimizes troubleshooting.
