MR. JO JR 3253 – Modified BPA-BPF Epoxy Resin for Durable, Crystallization-Resistant Performance
In epoxy chemistry, formulators often face a classic challenge: balancing processing ease with long-term stability. While BPA-based resins are widely used, they are prone to crystallization under certain conditions. On the other hand, BPF-based resins bring better resistance but differ in handling and cost.
JR 3253 bridges this gap. It is a modified blend of BPA and BPF epoxy resins, engineered with a multifunctional aliphatic reactive diluent to provide superior crystallization resistance without compromising on performance.
Technical Profile
- Epoxy Equivalent Weight (EEW): 190 – 200 g/eq
- Viscosity @ 25°C: 700 – 1100 mPa·s
- Color (Gardner): ≤ 0.5
- Density @ 25°C: 1.05 – 1.15 g/cc
This medium EEW and controlled viscosity profile make JR 3253 easy to handle in coatings, construction chemicals, and composites.
Key Features
- BPA + BPF hybrid backbone – combines toughness of BPA with chemical resistance of BPF.
- Modified with multifunctional aliphatic reactive diluent – enhances flow, wetting, and workability.
- Outstanding crystallization resistance – stable during storage and application.
- Versatile performance – suited for solvent-free systems and high-solids formulations.
- Excellent clarity and low color – ideal for coatings where appearance matters.
Applications
- JR 3253 is designed for industries that demand durable and stable epoxy systems:
- Coatings – solvent-free and high-solid coatings for industrial, protective, and decorative use.
- Construction chemicals – flooring, repair mortars, primers, and grouts requiring reliable bond strength and resistance.
- Civil engineering applications – gap filling, waterproofing, and structural protection.
- General composites and adhesives – where stability and mechanical performance are essential.
Why Choose JR 3253?
- If you are struggling with resin crystallization in storage, JR 3253 offers a robust alternative.
- If you need a balance of BPA’s strength and BPF’s resistance, this hybrid resin provides both.
- If your formulations require easy processing, low viscosity, and dependable performance, JR 3253 fits seamlessly.
In short, JR 3253 is the crystallization-resistant epoxy resin solution that enables reliable performance in coatings, construction, and civil engineering systems.
