MR. JO Bondkot-HV – Strength Where It’s Needed Most
Grey. Gritty. Guaranteed to bond – even when other systems fail
🧩 The Challenge
When it comes to bonding concrete to concrete, precast elements, or even segment joints, there’s little room for error. Most failures trace back to moist surfaces, movement at joints, or the use of bonding agents that simply can’t take the mechanical and thermal stress of construction environments.
Many standard epoxies work well on ideal surfaces — but job sites are rarely ideal.
That’s where MR. JO Bondkot-HV steps in — a high-viscosity, grey-colored epoxy bonding system engineered to handle imperfect substrates and high-performance demands.
🧑🔧 Who is it For?
- Civil contractors working on segmental bridge joints
- EPC companies laying precast RCC beams, columns, kerbs
- Builders executing old-to-new slab connections or wall extensions
- Professionals needing a sag-resistant, thick epoxy adhesive
🏗️ What it Bonds and Seals
- Precast concrete bonding
- Segment joints
- Construction joints
- Old-to-new concrete interfaces
- Uneven or damp concrete patches
Thanks to its sag-resistant, thick consistency, Bondkot-HV can also be used for vertical and overhead bonding where flowable epoxies would fail or drip.
🔧 Key Technical Features
| Property | Value |
| Color | Grey |
| Mix Ratio (PBW) | 100:40 |
| Pot Life (@25°C) | 60–80 minutes |
| Mixture Consistency | Thick, floppy liquid |
| Surface Tolerance | Works on moist, underprepared surfaces |
| Appearance after curing | Opaque |
| Bond Strength | Exceptional on concrete and masonry |
🧱 Surface Prep? Yes — but forgiving
Bondkot-HV performs impressively even when:
- The substrate is moist or slightly under-prepared
- There is minimal mechanical keying
- Roughness is present due to grinding or chipping
Still, for best results, standard cleaning and degreasing procedures are recommended.
🧪 What Makes HV the Flagship?
- Thick-bodied: Stays where it’s placed. Ideal for verticals, joints, and uneven zones
- Moisture-tolerant: Doesn’t fail due to surface dampness
- Ready for filler loading: Can be bulked with quartz to make epoxy mortar
- Consistent grey color: Offers a uniform professional finish
- Reliable strength: Ensures structural integrity in segment bonding and precast jobs
🚧 Example Projects & Applications
- Segmental flyovers and bridges
- RCC water tanks with old-to-new additions
- Building retrofits and slab extensions
- Bonding of granite or tile layers to epoxy
- Foundation machinery bases in industrial plants
🔗 Part of a Powerful Series:
The Mr. JO Bondkot range includes a full suite of bonding epoxies for various jobs and flow preferences:
| Product | Viscosity | Pot Life (25°C) | Use Cases |
| HV | High | 60–80 min | Segment bonding, joints, moist surfaces |
| STD | Medium | 40–65 min | Crack sealing, old-new bonding, can be filled |
| MVC | Low | 120–150 min | Foundation grouting, old-new bonding, protective coating |
| LVC | Medium | 100–120 min | Adhesion promoter, screed base, protective coating |
| UPS | Medium | 80–100 min | Moist surface bonding, sealer coat, precast connections |
When your job site isn’t perfect — when moisture is a factor, or strength can’t be compromised — MR. JO Bondkot-HV is the reliable grey workhorse you need.
It’s more than a bonding agent — it’s bonding confidence
