MR. JO JX 7012 – Di-Functional Reactive Diluent for Tougher, More Durable Epoxy Systems
MR. JO JX 7012 – Di-Functional Reactive Diluent for Tougher, More Durable Epoxy Systems
Introduction
Not all reactive diluents are created equal. While mono-functional types focus on improving flow and flexibility, di-functional diluents strike a balance between viscosity reduction and added performance in the cured network. JX 7012 is a di-functional aliphatic reactive diluent based on 1,4-butanediol diglycidyl ether. Similar to RD103, it is widely used in coatings, adhesives, and filament winding where strength, toughness, and chemical resistance are critical.
🔹 Technical Data Highlights
- Chemistry: Di-functional aliphatic reactive diluent (1,4-butanediol diglycidyl ether)
- Epoxy Equivalent Weight (EEW): 130–150 g/eq
- Viscosity (@ 25 °C): 12–25 mPa·s
- Color (Gardner): ≤ 17
- Density (@ 25 °C): 1.05–1.12 g/cc
🔹 Performance Benefits
✅ Improves toughness – enhances impact strength and flexibility.
✅Retains chemical resistance – unlike mono-functional diluents, it does not compromise resistance as much.
✅Moderate viscosity reduction – lowers viscosity without making the system too soft.
✅Better mechanical balance – maintains hardness and strength while improving workability.
Applications
- Industrial & protective coatings – improves toughness and chemical resistance in heavy-duty environments.
- Structural adhesives – provides stronger bonding with resistance to impact and chemicals.
- Filament winding & composites – ensures smooth fiber wet-out while retaining cured part durability.
- Flooring systems & mortars – adds toughness and long-term durability against abrasion.
🔹 Comparison Note
JX 7012 is comparable to Aditya Birla RD103 and other di-functional aliphatic reactive diluents. Its chemistry makes it a bridge between mono-functional diluents (better flow, less strength) and tri-functional modifiers (higher crosslinking, less flexibility). This balance makes it especially valuable in structural and industrial epoxy formulations.
🔹 Usage Tips
- Recommended PHR range: 5–15% depending on system and application.
- Works best when toughness and chemical resistance are priorities.
- Avoid excessive loading (>20%), as it may increase cure time and affect clarity.
- Compatible with bisphenol-A/B resins and a wide range of curing agents (aliphatic, cycloaliphatic, and polyetheramines).
🔹 Closing
If your epoxy system requires more toughness without sacrificing chemical resistance, JX 7012 is the right choice. From coatings that withstand harsh chemicals to adhesives that hold under impact, it offers formulators a reliable way to upgrade performance while maintaining processing ease.
