HINCOL Emulsion MS

Medium Setting | IS 8887:2004 | Cold Mix

HINCOL Emulsion MS is a specially designed water-based Bitumen Emulsion with moderate viscosity and medium setting time — the go-to solution for Pothole Repair, Patch Work, and 20mm Pre-Mix Carpet on Indian roads. Chocolate brown in colour and free-flowing at ambient temperature, it is manufactured strictly as per IS 8887:2004.

As part of HINCOL’s complete bitumen emulsion range, MS Emulsion occupies the critical middle ground between rapid setting (RS) and slow setting (SS) emulsions. Its 30-minute setting time provides exactly the right working window — enough time for thorough mixing and proper placement, yet fast enough for a stable, durable repair. It bonds well with cool and damp surfaces and is resistant to stripping by water — making it reliable year-round.

⏱️

30-Minute Working Window

Medium setting time of 30 minutes — enough for thorough premix preparation and proper placement without the risk of premature break during application.

🌧️

Works on Damp Surfaces

Bonds well with cool and damp substrates — resistant to stripping by water. Repairs can be done in wet weather when hot mix asphalt is not feasible.

🔧

Minimum Prep Time

Minimum surface preparation time required — making it the most efficient choice for pothole and patch repair on rural and district roads.

🌡️

No Heating Required

Applied at ambient temperature — eliminates energy cost, fire hazard, and the need for hot mix plant equipment. Ideal for remote site repairs.

🛡️

Stable Patch

Forms a durable, stable repair that withstands traffic loads — high adhesive properties ensure the patched area bonds firmly to the surrounding pavement.

💰

Cost Efficient

One of the most cost-effective road maintenance solutions — no hot mix plant, no fuel for heating, no specialized equipment required for basic pothole repair.

Understanding Setting Time — Why MS is the Right Grade for Cold Mix

The setting time determines how quickly the emulsion breaks (water separates from bitumen). Choosing the right grade is critical for the application type.

RS1 / RS2
Breaks in ~10 min
Tack Coat, Surface Dressing — no mixing needed
MS ← You Are Here
Setting Time: 30 minutes
Pothole Repair, Pre-Mix Carpet — needs mixing time ✅
SS1 / SS2
Breaks slowly (hours)
Prime Coat, Fog Seal — deep penetration needed

RS emulsions break too quickly for premix — aggregate won’t be coated uniformly. SS emulsions take too long — the mix won’t gain strength fast enough. MS at 30 minutes is the correct choice for cold mix applications.

Pothole Repair Using HINCOL MS Emulsion — Step-by-Step

1

Pothole Preparation

Clean the pothole area — remove loose debris, water, and loose asphalt particles. Trim jagged edges to create clean, vertical faces for better bonding with the patch material.

2

Cold Mix Preparation

Prepare the HINCOL MS cold mix at 7% emulsion by weight of aggregates. Mix thoroughly at ambient temperature until aggregates are uniformly coated — no hot plant or heating required.

3

Fill the Pothole

Pour the prepared HINCOL MS cold mix directly into the pothole, slightly overfilling to allow for compaction. Spread evenly to ensure complete coverage of the repair area.

4

Compact the Patch

Compact firmly using a hand tamper, plate compactor, or vehicle wheels. Compact in layers if depth exceeds 50mm. Proper compaction is critical for durability and stability of the patch.

5

Curing

Allow the patch to cure — HINCOL MS emulsion sets in approximately 30 minutes. Curing time may vary with temperature and humidity. The patch hardens further under traffic over time.

Why HINCOL Emulsion MS is the Ideal Cold Mix Binder

✅ 30-Min Setting — Perfect for Premix

Unlike RS grades that break too fast and SS grades that break too slow, MS at 30 minutes gives exactly the right working window for cold mix preparation and placement.

✅ Damp Surface Bonding

Bonds effectively with cool and damp surfaces — repairs are possible even in wet weather when hot mix asphalt operations are not feasible.

✅ Water Stripping Resistance

Resistant to stripping by water — the bitumen film remains bonded to aggregate particles even under wet traffic conditions, preventing premature failure of the patch.

✅ Stable, Durable Patch

High adhesive properties and stable mix ensure the repaired area holds up under heavy traffic loads — not a temporary fix, but a durable repair solution.

✅ Easy & Uniform Mixing

Easy to mix with aggregate at ambient temperature — no specialized mixing equipment needed. Suitable for use by road maintenance crews without technical expertise.

✅ Year-Round Usability

Low temperature curing — can be used in cold weather conditions where hot mix asphalt operations are impractical. Environment-friendly, no petroleum solvents.

✅ To Ensure Best Results — HINCOL Emulsion MS

  • Use without diluting with any solvent — dilution changes setting characteristics
  • Apply at ambient temperature — no pre-heating required or recommended
  • Roll drums 5 times before opening to ensure uniform consistency
  • Mix at exactly 7% by weight of aggregates — too little or too much affects stability
  • For pothole repair, compact in layers if depth > 50mm for maximum stability

Frequently Asked Questions

What is HINCOL Emulsion MS used for?

HINCOL Emulsion MS is a Medium Setting Cationic Bitumen Emulsion used for Pothole Repair, Patch Work, and 20mm Pre-Mix Carpet construction. Its 30-minute medium setting time provides sufficient working time for mixing with aggregates in cold mix applications — making it the preferred binder for road maintenance and repair without hot mix plant.

What is the setting time of HINCOL Emulsion MS?

HINCOL Emulsion MS has a setting time of 30 minutes. This is a unique specification that differentiates MS from RS (breaks in ~10 min — too fast for mixing) and SS (breaks very slowly — too slow for patch repair). The 30-minute window is ideal for thorough cold mix preparation, placement, and compaction.

What is the application rate for HINCOL MS emulsion in premix?

The typical application rate of HINCOL Emulsion MS for preparation of cold mix is 7% by weight of aggregates. This applies to premix carpet and pothole repair cold mix preparation. Actual rate may vary based on aggregate gradation and mix design.

Can HINCOL MS emulsion be used in wet or rainy conditions?

Yes. One of the key advantages of HINCOL Emulsion MS is that it bonds well with cool and damp surfaces and is resistant to stripping by water. Pothole repairs can be done in wet weather conditions when hot mix asphalt is not feasible — making MS ideal for year-round road maintenance in India’s monsoon conditions.

What is the difference between RS, MS, and SS bitumen emulsions?
  • RS (Rapid Setting) — RS1, RS2: Breaks in ~10 min on aggregate contact. Used for Tack Coat and Surface Dressing — no mixing required.
  • MS (Medium Setting) — MS: Setting time ~30 min. Used for Pothole Repair and Pre-Mix Carpet — needs working time for mixing and placing.
  • SS (Slow Setting) — SS1, SS2: Breaks slowly over hours. Used for Prime Coat and Fog Seal — needs deep penetration into pores.

Choosing the wrong grade causes failures — RS in premix breaks before mixing is complete; SS in patching delays strength gain too long. MS is the correct choice for cold mix applications.

Does HINCOL MS emulsion need to be heated before use?

No. HINCOL Emulsion MS is applied at ambient temperature — no heating required. Roll drums 5 times before use to ensure uniform consistency. Never dilute with any solvent.

What is 20mm Pre-Mix Carpet and how is MS emulsion used in it?

20mm Pre-Mix Carpet (PMC) is a cost-effective thin wearing course used on rural and district roads. A cold mix of emulsion and graded aggregate (20mm nominal size) is prepared using HINCOL MS emulsion at 7% by weight of aggregates and spread over the primed road surface. It provides a riding surface, improves skid resistance, and protects the base from water. HINCOL MS is the preferred emulsion for PMC due to its medium setting time and strong aggregate adhesion.

What standard does HINCOL Emulsion MS conform to?

HINCOL Emulsion MS is manufactured strictly as per IS 8887:2004 — the Indian Standard for Cationic Bitumen Emulsion for Roads. It is classified as Medium Setting (MS) grade with a setting time of 30 minutes and minimum 65% binder residue by evaporation.

What is the shelf life and storage requirement for HINCOL MS?

HINCOL Emulsion MS has a shelf life of 12 months when stored at temperatures between 10°C and 50°C. Never allow to freeze or heat above 85°C. Store away from direct sunlight. Reseal containers after use.
