Colas Leotak K140 – Premium Tack Coat Bitumen Emulsion

The Colas Leotak K140 25kg is a cold-applied, rapid-acting 40% cationic bitumen emulsion, specially formulated to provide excellent adhesion between bituminous overlays and existing road surfaces. Once cured, it forms a thin, uniform film of bitumen that bonds securely while preventing water penetration between pavement layers.

Key Features:

• Strong Adhesion: Delivers a secure bond between overlays and existing surfaces.
• Works in Damp Conditions: Reliable performance even in less-than-ideal weather.
• Water-Resistant: Hinders entry of water between road pavement layers.
• Cold-Applied & Rapid-Acting: Easy to use, with quick curing for efficient projects.
• Versatile Applications: Suitable for carriageways, footways, car parks, overlays, patching, and inlaid work.
• Complies with Standards: CE Marked to BS EN13808:2013 C40B and meets withdrawn BS434-1 K1-40.

Application Guidance:

• Ensure the surface is clean, free of detritus, water, loose material, and oil.
• Apply by spray or hand at 0.3–0.6 l/m², depending on surface porosity and texture.
• Keep traffic off until emulsion has fully broken (colour change from brown to black).
• Once cured, apply the overlay for best results.

With proven performance and compliance to industry standards, Colas Leotak K140 is a trusted choice for tack coating in road construction and maintenance.
