KuwaitKey features and product advantages of our RS 1 (Primer)
Where our RS 1 (Primer) provides maximum road safety and protection
RS-1 primer is the recommended bond coat for pothole patches before applying cold mix asphalt.
RS-1 is used as a tack coat between existing bituminous layers and new asphalt overlays.
RS-1 primer seals granular sub-bases prior to bituminous surfacing on new road construction.
Used by municipal corporations for routine pothole and crack maintenance on city streets.
RS-1 ensures durable patch repairs at toll plazas and intersections subject to braking stress.
Suitable for heavy-duty pavement maintenance in industrial estates, ports, and container yards.
RS-1 Primer & Pothole Repair Market Growth | YNM Safety
The Indian bitumen emulsion market is projected to grow at a 5–7% CAGR through 2030, driven by accelerated highway maintenance programs under NHAI, PMGSY rural connectivity expansion, and municipal pothole repair initiatives across smart cities.
As trusted RS-1 primer manufacturers, YNM Safety produces cationic bitumen emulsion through a controlled colloid mill process to deliver consistent particle size, stable storage performance, and rapid setting characteristics for pothole repair and pavement priming.
VG-10 or VG-30 paving grade bitumen is selected as the base feedstock based on the required emulsion residue and end-use specification. Each batch is tested for penetration, softening point, and ductility before entering the emulsification process.
Demineralised water is blended with cationic emulsifying agents and a controlled dose of hydrochloric acid to achieve the optimal pH window. This aqueous phase carries the positive charge that defines RS-1 emulsion behaviour.
The selected bitumen is heated to 130–150°C in jacketed storage tanks under continuous agitation. Temperature is closely monitored to ensure proper viscosity for colloid mill processing without thermal degradation.
Heated bitumen and aqueous phase are simultaneously fed into a high-shear colloid mill operating at 3,000–6,000 rpm. The mill disperses bitumen into micron-sized droplets coated with emulsifier, producing a stable cationic emulsion.
The freshly produced emulsion is cooled through heat exchangers and transferred to stabilisation tanks. A controlled rest period ensures complete emulsifier adsorption and uniform particle size distribution.
Each batch is tested for residue on sieve, Saybolt Furol viscosity, particle charge, storage stability, residue by evaporation, and water content per IS 8887. Only batches meeting all parameters are released.
Approved RS-1 emulsion is filled into 200 kg steel drums via automated filling lines, with each drum batch-labelled and sealed. Bulk tanker loading is available for project-based supply.
Batches are dispatched with test certificates, MSDS, and batch traceability documents. YNM Safety supports pan-India delivery and export shipments with technical assistance for application crews.
