MC-Bauchemie MC-DUR 1300 VK Grip
A plasticized two-component epoxy binder from MC-Bauchemie’s Whisper-Grip anti-skid surfacing system, engineered to bond tough, high-friction wearing courses onto bituminous roads and to prime mineral substrates.
What is it?
A slightly thixotropic, plasticized two-component epoxy resin binder from MC-Bauchemie, used as the reactive binder in high-friction, noise-reducing anti-skid surfacing and as a versatile primer and scratch-coat binder.
Where is it used?
Bituminous traffic routes such as mastic asphalt, hot-rolled asphalt and stone mastic asphalt, plus mineral, ceramic and steel substrates ahead of reactive resin flooring in industrial areas.
Why use it?
It stays flexible enough to move with an asphalt deck yet cures rapidly to lock down polish-resistant grip aggregate, restoring skid resistance and cutting tyre noise where a rigid coating would crack.
How is it applied?
Metered through two-component dosing equipment at the correct 2.94:1 ratio, cast-levelled onto the deck and immediately broadcast with grip aggregate; as a primer it is applied by squeegee, float or roller.
About MC-Bauchemie MC-DUR 1300 VK Grip
MC-DUR 1300 VK Grip sits in a specialised corner of the MC-Bauchemie floor and traffic-route range: it is the reactive epoxy binder that holds MC’s approved Whisper-Grip anti-skid system together. Unlike a rigid industrial floor coating, this resin is deliberately plasticized so that it can flex with the movement of a bituminous carriageway instead of debonding or micro-cracking. Applied through two-component dosing equipment, the resin is cast-levelled onto a prepared asphalt surface and a hard, polish-resistant grip aggregate is broadcast into it while the film is still wet. The result is a durable wearing course that dramatically raises skid resistance (SRT/SCRIM values) on bends, ramps, toll plazas, tunnel approaches and traffic-jam sections, while noticeably reducing tyre noise.\n\nBeyond its headline role in road surfacing, the same resin doubles as a workhorse in reactive-resin flooring. It primes mineral-based substrates and non-absorbent surfaces ahead of epoxy or PU coatings, and acts as the binder for epoxy scratch and levelling coats where a fine, hard-wearing feather-edge is needed. For Indian contractors and consultants, that dual identity matters: one drum can serve a high-friction surfacing package on infrastructure work and a primer or repair-mortar binder on an industrial floor. Space Arc Engineering supplies MC-DUR 1300 VK Grip as an authorised MC-Bauchemie channel across Delhi NCR and pan-India, with technical support on substrate readiness and system selection.
The technical insight
The performance of MC-DUR 1300 VK Grip comes from a balance most epoxies do not attempt. A standard high-strength epoxy is stiff and brittle once cured, which is fine on a rigid concrete slab but fatal on flexing asphalt, where thermal movement and traffic deflection would quickly crack a hard film and pop the grip aggregate loose. MC-Bauchemie plasticizes the resin so the cured binder retains meaningful elongation (approximately 4.3% at break per DIN 53455) while still developing a high pull-off strength of roughly 38.6 N/mm2. That combination lets the film move with the bituminous deck yet grip the substrate and the aggregate hard enough to survive heavy, repeated wheel loads. The slightly thixotropic body stops the wet resin from running off cambers and slopes up to about 7%, and the rapid cure means the aggregate is captured before it can be dislodged. Skid resistance itself is delivered by the polish-resistant grains broadcast into the binder rather than by the resin alone, so the wearing course holds its friction value long after untreated asphalt has polished smooth. Because the film is thin and reactive, correct two-component metering at the 2.94:1 ratio and a short working window (pot life around 13 minutes at 27C) are what govern success on site.
Where it is used
- Anti-skid, noise-reducing wearing courses on mastic asphalt, hot-rolled asphalt and stone mastic asphalt as part of the Whisper-Grip system
- High-friction surfacing on accident-prone bends, gradients, roundabouts and pedestrian-crossing approaches
- Toll plazas, ramps and tunnel-approach sections where braking friction and tyre-noise reduction are both required
- Priming mineral-based substrates and non-absorbent surfaces before reactive-resin (epoxy/PU) floor coatings
- Binder for epoxy resin scratch coats and levelling coats on industrial floors
- Adhesion coat onto ceramic and steel surfaces ahead of resin build-ups
- Vertical and sloped detailing when blended with MC-Stellmittel TX 19 thixotropic agent
- Industrial traffic areas and yards needing durable, friction-retaining surfaces
Key advantages
- Plasticized formulation flexes with bituminous decks, resisting the cracking and debonding that defeat rigid coatings on asphalt
- High pull-off strength (approx. 38.6 N/mm2) with useful elongation (approx. 4.3%) balances grip and flexibility
- Polish-resistant grip aggregate sustains skid resistance and high SRT/SCRIM values under heavy traffic
- Rapid cure captures broadcast aggregate quickly and shortens lane-closure and traffic-diversion time
- Excellent adhesion to mineral, ceramic and steel substrates broadens its use beyond road surfacing
- Slightly thixotropic body allows work on cambers and slopes up to about 7% without slumping
- One product serves multiple roles: anti-skid binder, flooring primer and scratch/levelling-coat binder
- Part of the officially approved Whisper-Grip system, giving specifiers a documented, tested surfacing package
Limitations & considerations
- Short pot life of roughly 13 minutes at 27C leaves a narrow working window and demands well-drilled application
- Requires two-component metering/dosing equipment and trained crews for the surfacing application, not a simple hand-mix job
- Substrate and material temperature must stay above +10C and relative humidity below 85%, limiting monsoon and cold-weather windows
- Intensive substrate preparation is essential; dirt, excess bitumen and loose particles must be removed or bonding fails
- Exposure to UV and chemicals can cause colour change; a brownish resin is not suited to decorative or colour-critical finishes
- Slopes steeper than about 7% need MC technical advice and a thixotropic-agent adjustment rather than standard application
Selection & best practice
Success with MC-DUR 1300 VK Grip is decided by preparation and timing more than by the resin itself. Prepare the substrate intensively, remove dirt, excess bitumen and loose particles, and confirm the deck, material and air are all above +10C, relative humidity is below 85%, and the surface is at least 3 K above dew point. Meter the two components accurately at the 2.94:1 ratio through proper dosing equipment; do not eyeball or extend the mix, because the roughly 13-minute pot life at 27C leaves no room to correct a bad batch. For anti-skid work, cast-level the resin free of atomised spray, broadcast the polish-resistant aggregate immediately while the film is wet, and lift masking tape before the resin gels. On slopes up to 7% the thixotropic body holds; for steeper or vertical work add about 3-5% by weight of MC-Stellmittel TX 19 and seek MC advice. As a primer, apply by float, squeegee or roller and, if it cannot be overcoated within 24 hours, blind the fresh film with oven-dried 0.1-0.3 mm quartz sand to guarantee the next coat keys in. Allow the film-forming interval (about 20 minutes at the minimum temperature) before trafficking, and store unopened packs cool and dry, protected from frost.

How we position MC-Bauchemie MC-DUR 1300 VK Grip
MC-DUR 1300 VK Grip is a specialist within MC-Bauchemie’s MC-DUR floor and traffic-route family rather than a general-purpose floor coating, so it is best specified alongside the products that complete its system. For the anti-skid surfacing role it works with the polish-resistant grip aggregate and MC-Stellmittel TX 19 thixotropic agent for sloped and vertical detailing. Where it is used as a flooring primer or scratch-coat binder, it pairs naturally with MC-Bauchemie’s MC-DUR epoxy topcoats and self-levelling floor systems that Space Arc also supplies. If a project needs a clear, low-viscosity primer for absorbent concrete rather than an anti-skid binder for asphalt, MC-DUR 1200 VK is the more suitable MC option. Across our other brands, teams building conventional industrial epoxy floors on concrete often look to Fosroc’s Nitoflor flooring range or Sika’s Sikafloor systems; our technical team can help match the right primer-and-topcoat combination to the substrate. Because MC-DUR 1300 VK Grip’s core purpose is high-friction, noise-reducing surfacing on bituminous roads, it should not be substituted with a standard concrete floor coating on that duty.
