Anticorrosion Viscoelastic Putty
VISCO Elastic Putty — Moldable Protection for Complex Pipeline Geometry
Our Anticorrosion Viscoelastic Putty is a hand-moldable, cold-applied protective compound engineered to fill voids, profile irregular surfaces, and protect complex geometries on pipelines, fittings, and field joints. Built on advanced VISCO Elastic putty technology, it provides a smooth, continuous substrate for subsequent tape wrapping while delivering its own corrosion protection performance.
What Is VISCO Elastic Putty?
VISCO Elastic putty is a dimensionally stable, highly conformable compound that combines viscous cold-flow behavior with elastic recovery. Unlike conventional mastics that harden or shrink over time, VISCO Elastic putty:
Remains permanently soft and moldable — does not dry out, crack, or shrink
Cold-flows into voids — fills pits, weld seams, pinholes, and irregular surfaces
Provides a smooth profile — creates an even surface for tape application
Self-heals — minor damages close automatically under compression
Maintains adhesion without primers or heat
This makes it ideal for applications where surface irregularity or complex geometry would otherwise compromise the integrity of a tape wrapping system.
Key Features & Benefits
Hand-Moldable, Cold-Applied — No heat, no mixing, no special equipment required
Excellent Void Filling — Fills pits, weld spatter, pinholes, and irregular weld profiles
Permanent Flexibility — Does not harden, crack, or shrink over time
Self-Healing Behavior — Minor damages close under compression
Compatible with Tape Systems — Provides an ideal substrate for viscoelastic and petrolatum tapes
Wide Temperature Range — Stable performance across low and elevated service temperatures
Excellent Corrosion Protection — Forms a continuous barrier against moisture, oxygen, and corrosive soils
Compatible with Cathodic Protection — Does not shield CP current
