Advantages
At the following you can find some advantages of this product:
· Environment friendly
· No heating required
· Cost efficient
· Easy and uniform spray
· Low temperature curing, fast setting time
· High adhesive properties
· Prevents slippage of structural layers
Applications
Main application of CRS asphalt emulsion is using for surface treatment projects as:
· Single surface treatment
· Multiple surface treatment
· Sand seal
BACCO Bitumen Emulsion CRS1 is ideally suited for Tack Coat application as well and other applications will see below:
· To ensure a proper bond between existing surface and the new bituminous course being placed over it.
· To ensure longevity of the road, it is important that the new bituminous surface bonds firmly with underneath surface
· To coat and bond loose mineral particle on the surface of the surface layer
· To seal surface pores and make the surface water-resistant
· To impart structural stability and prevent lateral movement of layer
· To assist adhesion between the base and super impose surface course
Tack coat application is a light spray of Bitumen Emulsion, which may be hand or machine sprayed. It is used to ensure a good bond between an old and a new bituminous surfacing layer. It is normally applied very thin and evenly over the entire surface.

To Ensure Best Result
· Use without diluting Bitumen Emulsion with water
· Use at ambient temperature
· Roll the Bitumen Emulsion drums to and fro motion at a distance of minimum 5 meter
Handling and safety
· Contains petroleum distillate; flammable: keep away from open fire, sparks or other ignition sources; wear protective clothing, gloves and goggles.
· Fire flammable when wet, flash point 40°C.
· Skin –avoid repeated or prolonged contact, if occurs remove with hand cleaner that removes oil or grease, then clean with soap and water.
· Eyes contact could cause irritation, if contact occurs flush immediately with clean water.
· Inhalation can cause dizziness, move immediately in fresh air if dizzy and if breathing difficulty persists administer oxygen.
Cleaning
Tools: Clean with kerosene.
Hands: Use a hand cleanser or kerosene followed by soap and water.
