Zinc-Rich Epoxy Coating
Star Strength Shield
Liquid Metal Coating for Long-Term Steel Protection
Star Strength Shield is a two-component, zinc-rich epoxy liquid metal coating built to stop corrosion before it starts. Designed for fabricators, contractors, and infrastructure teams working with structural steel and GI sheet, it delivers galvanic protection much like hot-dip galvanizing, minus the furnace and the wait. Zinc particles sacrifice themselves first, corroding in place of the steel underneath.
Unlike ordinary primers, this liquid metal coating combines fast curing, strong adhesion, and lasting durability in one product, extending the service life of steel components across construction, industrial, and marine projects.
6 Ways Star Strength Shield Solves Real Corrosion Problems
- Zinc-Rich Galvanic Protection — Zinc particles act as a sacrificial anode, protecting steel the same way hot-dip galvanizing does.
- Two-Component Epoxy Formula — A resin-and-hardener system that cures into a tough, corrosion-resistant liquid metal coating.
- Fast Drying and Curing — Tack-free within minutes and fully cured within days, even on humid job sites.
- High Mechanical Strength — Withstands abrasion, impact, and handling knocks on structural steel and GI sheet surfaces.
- Strong Substrate Adhesion — Bonds tightly to properly prepared steel for long-lasting, flake-free coverage.
- Single-Coat or Multi-Coat Versatility — Works as a standalone finish or as a zinc rich epoxy primer under a compatible top coat.

The Problem
3 Problems Without Proper Steel Protection
Structural steel exposed to moisture, stress, and time faces the same recurring failures. Star Strength Shield is designed to solve all three.
Rapid Corrosion
Humidity, moisture, and coastal conditions can quickly cause rust and corrosion on exposed steel.
Primer Failure
Standard primers may wear or deteriorate under mechanical stress and harsh environmental conditions.
Costly Steel Damage
Unprotected structural steel and GI sheets can suffer progressive corrosion, leading to higher maintenance and replacement costs.
Benefits
6 Ways Star Strength Shield Solves Real Corrosion Problems
Star Strength Shield is a two-component, zinc-rich epoxy coating designed to provide galvanic corrosion protection for structural steel and GI sheets. It offers strong adhesion, fast curing, and durable protection, helping extend the service life of steel in construction, industrial, and marine environments.
Long-Term Corrosion Resistance
Because zinc particles in this liquid metal coating corrode before the steel does, protection continues even if the surface gets scratched. This sacrificial action extends the service life of tanks, pipelines, and structural members exposed to weather and moisture.
Faster Project Turnaround
Fast tack-free and cure times mean crews can recoat or move equipment sooner instead of waiting days between steps. For contractors managing tight schedules, this liquid metal coating solution keeps corrosion protection work moving without stalling other trades on site.
Reduced Maintenance Costs
Strong adhesion and abrasion resistance mean the coating stays intact longer under mechanical wear, foot traffic, and weathering. Fewer touch-ups and repaint cycles translate directly into lower lifecycle maintenance spending for asset owners managing large steel structures.
Reliable Protection for GI Sheet and Damaged Galvanizing
Cut edges, welds, and drill holes strip away factory galvanizing and expose bare metal to rust. Applied as liquid metal protection for GI sheet, Star Strength Shield restores sacrificial protection to these vulnerable spots quickly and effectively.
Flexibility Across Application Methods
Whether applied by brush for detail work or airless spray for large surfaces, the formula stays workable and consistent. This flexibility makes it a practical liquid metal coating solution for both small repairs and large-scale structural steel projects.
Dependable Performance in Demanding Environments
From coastal humidity to industrial fumes, the cured film resists weathering and chemical exposure better than standard primers. Structural steel, pipelines, and storage tanks stay protected in conditions that would quickly degrade unprotected or poorly coated surfaces.
How to Apply
Application Method
Reliable galvanic protection starts with proper surface preparation and mixing.
Surface Preparation
Clean and blast the steel to Sa 2.5, removing rust, scale, and contaminants so the liquid metal coating can bond properly.
Mixing
Combine Part A and Part B in the specified ratio using a low-speed paddle mixer until a uniform grey colour is achieved, avoiding excessive air entrainment.
Application
Apply by brush or airless spray in one or two coats, working within the product's pot life and allowing correct recoat intervals between layers.

FAQs
Frequently Asked Questions
Everything you need to know about Star Strength Shield.
What is a liquid metal coating and how does it protect steel?
A liquid metal coating is a zinc-rich epoxy formulation applied like paint that gives steel galvanic protection. The zinc acts as a sacrificial layer, corroding first so the steel underneath stays protected.
Is Star Strength Shield liquid metal coating a substitute for hot-dip galvanizing?
Yes, in many cases. This liquid metal coating provides similar sacrificial, cathodic protection to hot-dip galvanizing but can be applied on-site with standard brush or spray equipment, without a galvanizing bath.
Can this product be used as liquid metal protection for GI sheet?
Yes. It works well as liquid metal protection for GI sheets, especially on cut edges, welds, and areas where the original galvanized coating has been damaged during fabrication or installation.
What is the mixing ratio for Star Strength Shield?
Star Strength Shield is a two-component system mixed in a fixed ratio of resin (Part A) to hardener (Part B) by weight. Always mix full units and follow the exact ratio for reliable curing.
How long does the liquid metal coating take to dry and cure?
The coating typically becomes tack-free within around 20 minutes and reaches full cure within about a week at normal ambient temperatures, though cooler conditions extend curing time.
What is the coverage rate for this zinc rich epoxy primer?
Coverage generally falls between 0.150–0.250 kg per square metre, depending on surface profile and application method. Rougher, blast-cleaned surfaces typically require slightly more material.
Can Star Strength Shield be applied by spray, or only by brush?
Both methods work well. This liquid metal coating can be brush-applied for detailed or small-scale work, or sprayed using airless equipment for faster coverage on large structural steel surfaces.
Is a top coat required after applying this liquid metal coating?
A top coat isn't always mandatory. For atmospheric exposure, a single coat can serve as the finish. For added durability or aesthetics, a compatible top coat can be applied over this zinc rich epoxy primer.
What surface preparation is needed before applying this liquid metal coating?
Steel should be clean, dry, and free of rust, oil, and old coatings. Blast cleaning to Sa 2.5 is recommended, with moisture content kept below 4% before application.
Where can Star Strength Shield liquid metal coating solutions be used?
These liquid metal coating solutions suit structural steel, pipelines, storage tanks, rebar, GI sheet, and marine structures across construction, industrial, and infrastructure projects that need long-term corrosion protection.
