Emulsion Bitumen – High-Quality Cationic & Anionic Grades — Export from Iran
Emulsion Bitumen is a water-based dispersion of bitumen stabilized by an emulsifying agent. It is an environmentally friendly and energy-efficient binder used in cold application methods such as surface dressing, chip sealing, slurry seal, and tack coats.
We supply premium-quality Emulsion Bitumen from advanced Iranian production facilities, available in both Cationic and Anionic types, with grades including SS (Slow-Setting), MS (Medium-Setting), RS (Rapid-Setting), and QS (Quick-Setting). Complies with international standards including ASTM D2397 and EN 13808.
Note: Cationic emulsions bond better with negatively charged aggregates (most common). Anionic types are used with specific aggregates and in special conditions.
🛣️ Janis Group Emulsion Bitumen Capability: We facilitate production-to-port supply of Cationic and Anionic grades (SS, MS, RS, QS) from certified Iranian emulsion plants, with full ASTM D2397 / EN 13808 compliance, SGS pre-shipment inspection, and time-sensitive logistics — essential given the limited shelf life of emulsions. We coordinate closely with buyers to align production date with vessel loading.

Applications
- Tack Coats: Bonding layer between asphalt layers (RS/QS)
- Surface Dressing: Chip sealing with MS/SS grades
- Slurry Seal: Preventative maintenance using SS
- Cold Mix Asphalt: For road patching and repairs
- Prime Coat: Sealing granular bases before asphalt layer
- Dust Control: On unpaved roads and construction sites
Which Setting Grade Fits Your Project?
SS (Slow-Setting)
Setting speed: Slow — extended workability window
Choose this if: You need extended mixing time — slurry seals, micro-surfacing, cold mix asphalt for patching, and stabilization works.
Typical buyers: Preventive maintenance contractors, cold mix producers, slurry seal specialists.
MS (Medium-Setting)
Setting speed: Moderate — breaks when worked into aggregate
Choose this if: You need a versatile binder for surface dressing, chip sealing, and general road maintenance with standard equipment.
Typical buyers: Road authorities, chip-seal contractors, municipality maintenance teams.
RS / QS (Rapid/Quick)
Setting speed: Fast — breaks on aggregate contact
Choose this if: Your project demands quick traffic reopening — tack coats, emergency repairs, chip seals on high-traffic roads.
Typical buyers: Highway agencies, urban maintenance contractors, emergency repair teams.
Key Notes
- Cationic Emulsions: Most widely used; bond well with silica-rich aggregates (granite, trap rock).
- Anionic Emulsions: Suitable for limestone and dolomite aggregates; less common but effective in specific conditions.
- SS (Slow-Setting): Used in slurry seals and cold mix asphalt for maintenance.
- MS (Medium-Setting): Ideal for surface dressing and chip sealing.
- RS/QS (Rapid/Quick-Setting): Used for tack coats and rapid repair projects.
- Shelf Life: 30–90 days depending on grade — production scheduled close to shipment date.
- Temperature: Must be kept between 5°C and 60°C during transport and storage (no freezing, no overheating).
- All batches tested for stability, particle charge, and residue quality.
- Pre-shipment inspection by SGS included for every shipment.
Frequently Asked Questions (FAQ)
Cationic (pH 2–3, positive charge) bonds with silica-rich aggregates like granite and basalt — covering 90%+ of global road aggregates. Anionic (pH 8–10, negative charge) is used with limestone and dolomite in specific regions.
SS = Slow (slurry seals, cold mix), MS = Medium (chip sealing, surface dressing), RS = Rapid (tack coats), QS = Quick (micro-surfacing). Setting speed determines application and shelf life.
30–90 days depending on grade. SS grades last up to 90 days; RS/QS grades should be used within 30–45 days. Storage must be above 5°C and below 60°C.
Minimum order is 200 MT, typically shipped in 180–200 kg steel drums loaded in 20ft containers. We schedule production close to vessel loading to maximize shelf life upon arrival.
Emulsions save fuel (no heating needed), comply with VOC regulations, and reduce burn risk. The trade-off is shorter shelf life and stricter temperature control during transport.
