COLABINDER
(Bitumen Emulsions)

We manufacture advanced bitumen emulsions that vary in composition and are designed for different construction and maintenance applications including road surfacing, patching, and stabilization. Produced at our Kinyerezi plant in Dar es Salaam.

What Are Emulsions?

Cold Way

Bitumen Emulsion is a bitumen dissolved in water by the aid of Emulsifiers and grinding force. Bitumen Emulsions enabies one to use bitumen while cold solve many challenges associated with Hotmixes Bitumen Emulsions are commonly used in road or pavement construction (85%), Industrial application (10%) and others like raw materials (5%). Bitumen Emulsions are in two major charges; Cationic - positively charged (+ve) and Anionic - negatively charged (-ve)

Starpeco manufactures the COLABINDER range at our own plant in Kinyerezi — with a production capacity of 20,000 litres per hour. This means we can supply consistent, specification-grade emulsion at project volumes without the supply chain uncertainty of imported products.

COLABINDER emulsions are designed for the specific temperature and traffic conditions of Tanzania's road network — and are tested to comply with TANROADS and UDSM Highway Laboratory specifications.

COLABINDER Range

Three Emulsions.
Every Application.

Each COLABINDER grade is formulated for a specific road construction or maintenance application — from tack coats to surface dressing to cold mix production.

Cationic Rapid Set · Tack Coat

COLABINDER CRS-60

Also known as K1-60 or Tack Coat. A cationic rapid-setting emulsion designed to bond between existing road surfaces and new asphalt layers. Breaks quickly on contact, minimising traffic disruption. The standard tack coat specified for most Tanzanian road projects.

CRS-60 K1-60 Tack Coat

Cationic Rapid Set · Surface Dressing

COLABINDER CRS-70

A higher-bitumen-content cationic rapid-setting emulsion specifically designed for surface dressing and chip seal applications. Provides a durable, weather-resistant surface seal for both new roads and rehabilitation works. Widely used on Tanzania's rural and secondary road network.

CRS-70 Surface Dressing Chip Seal

Cationic Slow Set · Cold Mix

COLABINDER CSS-60

Also known as CSS-1h. A slow-setting cationic emulsion — the primary binder in Starpeco's COLAMIX cold mix asphalt range. Provides extended workability time before breaking, enabling thorough mixing with aggregates for premixed asphalt production.
