Description

Densopol 80 & 80 HT are extremely tough cold-applied laminate tapes. The combination of PVC
backing and fabric-reinforced polymer bitumen adhesive makes it extremely resistant to damage by
sharp objects e.g. poor backfill.

Uses

For the corrosion protection of buried or immersed pipes and fittings. The tapes can be applied by
hand to weld joints, bends, bare pipe lengths and pipe fittings.

Features

• Cold applied
• Good comformability
• Good impact resistance
• Excellent adhesion to pipe and self
• Excellent resistance to cathodic disbonding
• Compatible with common pipe coatings
• Suitable for application by hand or machine on medium or large-diameter pipes

Application

Prepare steel to St2 (power brushed)/AS 1627 P.2 (minimum). Apply a thin film of Denso Primer D to
all surfaces to be protected and allow to tack dry. Peel back the interleaving and apply the adhesive side
of the tape to the primed surface and press down. Apply the tape spirally with enough tension to
make it conform. Remove interleaving as wrapping proceeds. Overlap each turn by 55% to achieve
double thickness.

Irregular surfaces such as valves, flanges, etc., may require the use of Denso Bitumen Mastic, Denso
Mastic or Denso Profiling Mastic. Refer to the product sheets for the specific product for information on the
application.
