Dkbutyl-System B 50

Dkbutyl-System B 50 (coating construction) cold-applied system for anticorrosion insulation of the outer surface of steel main pipelines up to and including 1220 mm in diameter. Dkbutyl-System B 50 (coating design) cold-applied system consists of primer Kebutyl-Primer K III and coextruded 2-layer polyethylene tape Dkbutyl-Tape 1.6. Dkbutyl-System B 50 meets the requirements of load class B with a maximum continuous operating temperature of 50°C. Kebutyl Primer K III is a quick-drying bitumen-butyl rubber primer (primer), which is applied to the prepared pipe surface before applying Dkbutyl-Tape 1.6. The primer is designed to promote adhesion between the pipe surface and the adhesive layer of the tape. Dkbutyl-Tape 1.6 is a coextruded 2-layer polyethylene tape made of stabilized, 100% polyethylene and a layer of bitumen-butyl rubber adhesive with butyl rubber content ≥70% with a siliconized film that prevents the tape coils from sticking together in the roll.
