Green Strength. Fast Build. Superior Chemical Resistance.
Green Strength. Fast Build. Superior Chemical Resistance.
In demanding environments where tanks, floors, and processing areas are exposed to corrosive solvents, acids, or fuels — and you still want a smooth, high-build, aesthetic finish — there’s one standout solution: MR. JO ProtectoKot – HBCR.
Unlike most chemically resistant coatings that are dull or patchy, HBCR goes on thick, stays green, and resists the worst of industrial abuse — all in 1 to 2 coats.
🧩 Where It Shines
- 🏭Chemical factories & solvent storage
- 🧪Drip trays & lab floors
- 🚢Marine interiors
- 🥼Pharma units
- 🔧Oil, fuel, and process pipelines
- 🏗️Industrial maintenance areas & machine rooms
🌱Where aesthetics + performance both matter
🛡️ What Makes HBCR Special?
HBCR is a modified epoxy formulation designed to offer:
✔️ High Chemical Resistance — acids, alkalis, solvents, water
✔️ High-Build Application — achieve 250–400 μm in 1 coat
✔️ Fast Recoating — short pot life allows quick progress
✔️ Low VOC, Solvent-Free — for enclosed or sensitive areas
✔️ Glossy Green Finish — for a clean, easy-to-inspect surface
✔️ Durable & Non-Porous — long service life, no peeling
🎯 Designed for Quick, Effective Protection
| Property | HBCR Performance |
| Mix Ratio | 100:14 pbw |
| Appearance | Green, glossy, high viscosity |
| Application | Brush, roller, trowel |
| Coat Thickness | 250–400 μm per coat |
| Pot Life | ~20–30 minutes at 25°C |
| Cure Time | Touch dry: 4–6 hrs; Full cure: 7 days |
| Coverage | 3–4 m²/kg/coat depending on substrate |
🧱 Use Cases & Real-World Success
“We were looking for a solvent- and acid-resistant floor coat for a blending room in a perfumery plant. The old PU-based coating peeled within 6 months. HBCR gave us a solid, green high-gloss coat that’s been holding up beautifully for over a year now.”

🛠️ Surface Preparation + Application
Substrates:
- Mild Steel (grit blasted to Sa 2.5)
- Concrete (roughened, dry, free from laitance)
Primers:
- Use MR. JO Primer-MVC or LVC for dry, smooth concrete
- Use MR. JO Primer-UPS for underprepared or damp surfaces
Application Steps:
- Mix resin + hardener thoroughly
- Apply using brush/roller
- Recoat after 6–8 hours (if needed)
- Full cure in 7 days
💡 One of HBCR’s greatest strengths: its ability to build thickness fast — fewer coats, less downtime, more durability.
🔗 Screed & Mortar Compatibility
Want to create a thick, filled floor or bund?
Simply blend HBCR (Part A:B) with Quartz sand (3:1 ratio) to create a chemical-resistant mortar — ideal for:
- Drain channels
- Bund walls
- Containment pits
- Sump linings
Seal with a final HBCR coat for pore-free protection.
✅ Why HBCR over CSA or CRH?
| Feature | HBCR | CSA | CRH |
| Chemical Resistance | ✅✅✅ | ✅✅✅ (solvents, acids) | ✅✅ (acids, mild solvents) |
| Aesthetic Finish | ✅ Glossy Green | ⚠️ Pale Yellow, Matte | ⚠️ Natural, Matte |
| High-Build in One Coat | ✅ Yes | ⚠️ No | ⚠️ No |
| Pot Life | ⚠️ Short (~20–30 min) | ⚠️ Very short (~10 min) | ⚠️ Medium (~30–40 min) |
| Floor & Wall Use | ✅ Ideal | ✅ | ✅ |
Choose HBCR when you want high coverage, fast application, and a tough, good-looking finish.
🧪 Final Word
MR. JO ProtectoKot – HBCR is the professional’s choice when you need:
✔️ High chemical resistance
