Anticorrosion Viscoelastic Adhesive Tape
VISCO Elastic — The Smart Choice for Long-Term Pipeline Corrosion Protection
Our Anticorrosion Viscoelastic Adhesive Tape is a high-performance, cold-applied protective wrapping system engineered for the corrosion protection of pipelines, fittings, flanges, and field joints. Built on advanced VISCO Elastic technology, the tape combines the conformability of a viscoelastic material with the durability required for long-term buried and immersed service.
What Is VISCO Elastic Technology?
VISCO Elastic refers to the unique dual behavior of the tape's adhesive compound: it behaves like a viscous liquid over time, allowing it to cold-flow and self-heal around irregular surfaces, while maintaining elastic recovery to resist mechanical stress and movement. This means the tape:
Cold-flows into pits, weld seams, and surface irregularities
Self-heals minor damages and gaps
Maintains adhesion without the need for heat or primers
Remains flexible across a wide temperature range
Unlike conventional petrolatum tapes, VISCO Elastic compounds do not dry out, harden, or crack with age.
Key Features & Benefits
Cold-Applied, No Heat Required — Simple wrap application; no primer, no torch, no special equipment
Excellent Conformability — Adapts to complex geometries, fittings, valves, and flanges
Self-Healing & Cold-Flow Behavior — Fills voids and minor surface defects automatically
Superior Corrosion Protection — Forms a continuous, watertight barrier against moisture, oxygen, and corrosive soils
Wide Temperature Range — Stable performance from low ambient temperatures to elevated service conditions
Long Service Life — Resistant to aging, UV exposure (when overwrapped), and chemical attack
Compatible with Cathodic Protection — Does not shield CP current
Easy to Inspect and Repair — No curing time; immediate backfill possible
