Tack Coat Bitumen

Bitumen Emulsion – Cationic – Tack Coat

Tack Coat is a light application of Bitumen Emulsion between hot mix asphalt layers designed to create a strong adhesive bond without slippage. Heavier applications may be used under porous layers or around patches where it also functions as a seal coat. Without Tack Coat the asphalt layers in a road way may separate which reduces the structural integrity of the road and may also allow water to penetrate the structure.

Tiger Cement Limited has the capability to Export and Supply the different Grades of Emulsion Bitumen – Cationic – Tack Coat K1-30, K1-40, K1-60 and K1-70 in compliance with National and International standards.
