Sustainable Bitumen Emulsion Manufacturers & Supplier in India

HINCOL bitumen emulsions are manufactured through a controlled industrial process at our plants across India, using COLAS SA France technology and base bitumen from HPCL refineries:

• Step 1 — Base bitumen preparation: VG-30 or VG-40 refinery bitumen from HPCL is heated to 150–180°C to reduce its viscosity for processing through the colloid mill.
• Step 2 — Emulsifier solution: Demineralised water is combined with a precisely dosed emulsifier — a surfactant that gives the bitumen droplets their electrical charge (cationic = positive, which is the charge of all HINCOL grades) — and acidified to the correct pH.
• Step 3 — Colloid mill processing: Hot bitumen and the emulsifier solution are simultaneously fed into a high-speed colloid mill — the key piece of equipment. The mill shears the bitumen into microscopic droplets of 1–10 microns and disperses them uniformly throughout the water phase.
• Step 4 — Grade determination: The emulsifier type, its concentration, and the processing conditions control the final grade — RS (rapid/fast break), MS (medium), or SS (slow). Polymer-modified grades such as HINTAC, CRS2P, and BONDCOAT include SBS or latex polymer added to the bitumen phase before milling.
• Step 5 — Quality control: Every batch is tested in HINCOL’s NABL-accredited laboratory — sieve test, viscosity, particle charge, storage stability, and residue properties — before release for dispatch.
• Step 6 — Storage and dispatch: Finished emulsion is stored in stainless steel tanks at 10°C–50°C and dispatched in bulk tankers or 200 kg drums (MS/RC/HDPE) to road construction and maintenance sites across India.

Bitumen emulsion is a liquid product where bitumen is dispersed as fine droplets in water using an emulsifier. It is produced by passing hot bitumen and water containing an emulsifier through a colloid mill. The emulsifier gives the droplets an electrical charge — cationic (positive) like all HINCOL grades, or anionic (negative) — that keeps them stable in water. When applied to road surfaces, the water evaporates and the bitumen droplets coalesce into a continuous bitumen film. This process is called breaking or setting.

• RS (Rapid Setting) — Breaks quickly on contact with aggregate. Used for tack coat and surface dressing where fast setting is needed. Examples: RS1, RS2, HINTAC.
• MS (Medium Setting) — Controlled setting rate. Used for premix applications and patching where longer working time is needed. Example: HINCOL MS.
• SS (Slow Setting) — Extended setting time for better penetration and mixing. Used for prime coat, fog seal, slurry seal, soil stabilization, and cold mix. Examples: SS1, SS2, SS2-Stab.

For standard tack coat between asphalt pavement layers — use HINCOL Emulsion RS1 (IS 8887 compliant, breaks in ~15 min). For premium projects where trackless application is needed (no aggregate pickup under construction traffic) — use HINCOL HINTAC polymer-modified trackless tack coat emulsion.

For prime coat on Wet Mix Macadam (WMM) or Water Bound Macadam (WBM) surfaces — use HINCOL EMULTRA PLUS SS1 (IS) to IS 8887 specification. For projects requiring ASTM compliance, use HINCOL HINPRIME SS1 (ASTM). Both penetrate 8–15mm into the base, waterproof the layer, and prevent ingress of surface water.

Full Depth Reclamation (FDR) is a pavement rehabilitation technique where the entire existing road structure is pulverized and treated with bitumen emulsion in place — creating a new stabilized base without importing new aggregates. HINCOL offers SS2-Stab and SS2-FDR for this application, with full laboratory mix design, field supervision, and quality control support from HINCOL’s technical team.

No. HINCOL bitumen emulsions are water-based and are applied at ambient temperature — no heating equipment required. This is one of the major advantages of emulsion over hot bitumen or cutback bitumen — significant savings in fuel, equipment, and safety risks. Emulsion should be stored at 10°C–50°C and never heated above 85°C during application.

HINTAC is HINCOL’s polymer-modified trackless tack coat emulsion — a premium product for high-traffic highways. Unlike RS1 (standard tack coat), HINTAC cures to a non-sticky, trackless state within minutes of application. This means construction vehicles can drive over the tack coat layer without picking up bitumen on their tyres — eliminating tracking, reducing contamination of adjacent lanes, and improving site cleanliness. HINTAC also provides superior interlayer bond strength for longer pavement life.

HINCOL bitumen emulsions are available in:

• Bulk supply — delivered via bitumen tankers to project sites or storage tanks (most economical for large projects)
• Drums — 200 kg MS/HDPE drums for smaller projects, remote sites, or standard tack coat applications

• Short term (3–5 days): Can be stored without special measures.
• Medium term (up to 2–3 weeks): Gentle weekly agitation or drum rolling to maintain homogeneity.
• Always store at 10°C–50°C. Never heat above 85°C. Never freeze. Never over-circulate by excessive pumping.
