System DK-BUT^®2426

Complies with international standards EN 12068 (class C 50), DIN 30672 (class C 50), ISO 21809-3 type 12А-1 (Тmax 50°C).
Cold applied 2-tape anti-corrosion system for the protection of metal pipes and pipelines under extreme corrosive conditions and mechanical stress.

System composition

Butyl Primer DK-BUT^®27
The primer is a homogeneous black liquid composition consisting of a polymer resin based on butyl rubber, elastomers, corrosion inhibitors, stabilizers, mixed with an appropriate type of solvent.

3-ply Wrap DK-BUT^®800 – 1 layer with 50% overlap
Co-extruded, asymmetric, 3-ply polyethylene tape, consisting of a stabilized polyethylene carrier film and an adhesive layer of butyl rubber on both sides.

Outer Wrap DK-BUT^®500 – 1 layer with 50% overlap
Co-extruded, 2-ply, polyethylene tape, consisting of a stabilized polyethylene carrier film and an adhesive layer of butyl rubber on one side.

Special advantages

Designed for corrosion protection of main pipelines of large nominal sizes.
Maximum mechanical and corrosion protection combined with outstanding tape flexibility.
Self-amalgamation (mixing) of the tapes in the overlap area forms an impermeable sleeve-like coating.
Virtually impervious to water vapor and oxygen.
Compatible with factory coated PE.
DK-BUT^® tapes are easy to apply by hand.
To ensure a quality and more efficient application, it is recommended to use original winding devices DK-WORKER^®.

Area of application

System DK-BUT^®2426 is a proven solution for the permanent prevention of pipe and weld corrosion in areas of increased risk of corrosion in new installations or refurbishment projects.

System DK-BUT^®2426 self-amalgamation, self-mixing ability in the overlap area creates a completely sealed impermeable sleeve-like coating.

System DK-BUT^®2426 is the ideal choice for pipes with both small and large nominal sizes.
