Stop Corrosion Before It Starts: Why MR. JO ProtectoKot-CR Is the Industry’s Go-To Barrier Coat
Stop Corrosion Before It Starts: Why MR. JO ProtectoKot-CR Is the Industry’s Go-To Barrier Coat
From effluent drains to factory floors, coastal machinery to chemical tanks — corrosion is not just ugly, it’s expensive, dangerous, and inevitable without the right protection.
And yet, many coatings fail due to improper prep, poor formulation, or short-lived adhesion.
MR. JO ProtectoKot – CR is here to change that — a solvent-free, high-performance epoxy coating trusted across industries for long-term protection of metal and concrete structures against corrosion and chemicals.
🧩 The Problem
Corrosion isn’t just about rust. In industrial settings, it means:
- Equipment failures
- Downtime losses
- Structural degradation
- Unsafe work conditions
Chemical processing zones, textile units, food and beverage plants, and even water treatment systems — all face aggressive exposure from moisture, solvents, and acidic fumes.
🧪 Concrete begins to dust.
⚠️ Steel starts to pit.
🚫 Standard paints peel and perish.
What’s needed is a proven epoxy system that holds up even when solvents, sulphuric acid, and saltwater don’t play fair.
🧪 The Solution: MR. JO ProtectoKot – CR
MR. JO ProtectoKot-CR is a solvent-free epoxy system that forms a dense, chemical-resistant film over sandblasted steel or etched concrete, offering:
- Long-term anti-corrosion protection
- Excellent solvent and acid resistance
- Strong adhesion to properly prepared surfaces
- Compatibility with quartz-filled screeds
With decades of field usage, MR. JO ProtectoKot-CR is a versatile workhorse in environments where safety, cleanliness, and corrosion resistance matter most.
⚙️ How It’s Used
✅ Compatible Surfaces:
- Mild steel & ferrous metals
- Concrete floors, tanks, bunds
✅ Surface Preparation:
- Metal: Sandblasting or grit blasting for rust removal. Follow with degreasing using trichloroethylene or hot air.
- Concrete: Sandblasting or mechanical abrading. If not feasible, acid etching using 15% HCl followed by water wash and drying.
🎯 Good adhesion = clean, rough, dry surface.
✅ Application:
- Mix ratio: 100:60 PBW
- Application: Brush or roller
- Primer:
- MR. JO Primer-MVC/LVC for dry surfaces
- Mr. JO Primer UPS for moist/under-prepared areas
✅ Coverage & Build:
- ~130–150 microns per coat
- Coverage: 4–5 m²/kg
- Typically 2–3 coats
- Touch dry in 4–6 hrs @ 25°C
Final cure: 7 days for full chemical resistance
