Guardian Visco Elastic Systems
Self-healing corrosion protection technology — non-curing, permanently flexible, and effective even on wet or contaminated surfaces for maintenance and asset life-extension.
Corrosion Protection That Remains Alive
Guardian Visco Elastic Systems use advanced non-curing materials that remain flexible and self-healing throughout their service life. Unlike conventional coatings that cure to a rigid film, visco-elastic materials flow around surface irregularities, self-seal minor defects, and maintain continuous barrier protection without cracking or disbonding.
Particularly effective for maintenance, in-service repair, and asset life-extension — where full surface preparation and coating replacement is not practical or economical. JST Group supplies and applies Guardian Visco Elastic systems as a complete, managed service.
Why Visco Elastic Systems?
The maintenance and repair coating of choice — self-healing, wet-surface compatible, and re-enterable for ongoing inspection programs.
No Curing Time
Non-curing material — immediately effective upon application with no waiting time before backfill or service return.
Excellent Wet Surface Adhesion
Bonds effectively to damp and contaminated surfaces — ideal for in-service repairs where full surface preparation is not possible.
Self-Healing Properties
The visco-elastic material flows into minor surface defects and self-heals when disturbed — maintaining continuous barrier protection.
Easy Inspection & Re-Entry
Remains removable and re-applicable throughout its service life — enabling non-destructive inspection and maintenance access.
Where Visco Elastic Systems Are Applied
Valves & Flanges
Protection of valve bodies, flanges, and fittings where petrolatum systems cannot achieve full coverage.
Offshore Pipelines
Asset life-extension for offshore pipelines with existing coating degradation — applicable on wet and corroded surfaces.
Maintenance & Repair Works
In-service repairs to corroded or coating-failed sections without plant shutdown or full surface blasting.
Complex Geometries
Pipe supports, tees, elbows, and mechanical assemblies where wrap systems are difficult to apply uniformly.
How We Deliver It
Visco elastic coating services — from specification and field application through to integration with asset integrity and maintenance programs.
System Specification
Assessment of surface condition and environment to define the correct visco-elastic system, primer, and outer protection.
Field Application
Application by trained technicians — ensuring full coverage, correct thickness, and outer wrap installation.
Asset Life-Extension Projects
Integration into planned maintenance programs to extend the service life of corroded or partially degraded assets.
Inspection Support
Re-entry and re-application services — supporting periodic inspection programs without full coating replacement.
System Overview
Guardian Visco Elastic systems consist of an inner visco-elastic compound applied directly to the steel surface, with an outer protective wrap to provide mechanical protection and UV resistance.
