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.
