Viscoelastic Adhesive Anticorrosion Inner Tape

Cold-Applied, Self-Healing Corrosion Protection for Pipeline Field Joints and Complex Geometry

Product Overview

Our Viscoelastic Adhesive Anticorrosion Inner Tape is a high-performance, cold-applied protective tape designed as the inner layer of a multi-layer corrosion protection system. Formulated with advanced viscoelastic adhesive technology, it cold-flows into surface irregularities, self-heals minor damages, and forms a continuous, watertight barrier against moisture, oxygen, and corrosive soils — without the need for heat, primer, or special equipment.

This product is specifically engineered for B2B pipeline projects requiring reliable, long-term corrosion protection in buried, immersed, and above-ground service conditions.

Key Features & Benefits

Typical Properties

System Integration

The Viscoelastic Adhesive Anticorrosion Inner Tape is designed as the inner protective layer of a complete corrosion protection system. Typical system configuration:

Surface Preparation — Clean steel to Sa 2½ or equivalent

Viscoelastic Adhesive Anticorrosion Inner Tape (this product)

Viscoelastic Adhesive Anticorrosion Outer Tape (mechanical protection layer)

Optional Outerwrap / Topcoat (for UV or high-abrasion environments)

This system is suitable for pipeline field joints, fittings, flanges, tank bottom chime edges, and coating rehabilitation.
