Bitulink emulsion CRS 1 is a product manufactured out of bitumen dispersed into the water in form of fine globules(micro size) by means of an emulsifying agent. The later acts to decrease interfacial stress between the bitumen and water thus preventing their breakage during normal condition of storage. This type of emulsion carries positive charges and is very much suitable for negatively charged aggregates exclusively and abundantly available in our country. The positively charged emulsion after getting in touch with the negatively charged aggregates deposes bitumen particles on the aggregates while water gets evaporated. This emulsion with low viscosity and fast setting time is an ideal product for spray application. Bitulink Emulsion RS 1 is manufactured strictly as per IS: 8887:2018 and ASTM: D 2397.
1. It comes in liquid form
2. It is chocolate brown in colour.
• It is applied cold thus saving energy in place of firewood or fuel oils.
• No health hazards because of absolute pollution free, thus environmental friendly.
• Easy and uniform spray.
• High adhesive properties.
• Except heavy downpour, construction in wet weather possible.
• Low temperature curing, fast setting time.
CRS 1 is ideally suited for tack coat application, single coat surface dressing. It is used for surface dressing (single/two coat). Can be applied on bituminous surface, aged bituminous surface, primed bituminous surfaces and non bituminous surfaces.
|Bitumen surface||2 to 2.5 Kg/ 10 Sq.m.|
|Aged bitumen surface||2.5 to 3 Kg/ 10 Sq.m.|
|Primed surface||2.5 to 3 Kg / 10 Sq.m.|
|Granular base (not primed)||3.5 to 4.0 Kg / 10Sq.m|

A medium Setting Emulsion is used for Premix carpeting, Pothole repairing, and tack coat. It can be used for road mixes with coarse aggregate for surface dressing and penetration macadam.
Slow Setting Grade Emulsion for application of Prime Coat. It consumes a long time to form continuous adhesion film without any stripping.
Thermoplastic Road Marking paints is widely used in highway and street construction, Available in White, Yellow, Red, and Blue.
