Emulsion Formula Composition of our tack coats

Tack coats consist of a cationic bitumen emulsion with 35-50, 70-100 or 160-220 penetrability.

Dosage of residual bitumen should be at least 300 g/m2 evenly spread.

CECA recommends the following emulsifiers for these applications:

• Dinoram S,
• Dinoram SL,
• Emulsamine L60,
• Emulsamine L70.

 

Typical formulations:

Penetration bitumen 35-50 ; 60% emulsion; break index 70
Dinoram S: 1.8 kg/tonne of emulsion
Aqueous phase pH = 2.0

Penetration bitumen 70-100; 65% emulsion; break index 70
Emulsamine L60: 2.0 kg/tonne of emulsion
Aqueous phase pH = 2.0
