Adhesives Technology Crackbond 2100 MV Medium-Viscosity Bonding Epoxy

Crackbond 2100 MV from Adhesives Technology is a two-component, medium-viscosity epoxy for bonding fresh concrete to hardened concrete and for coating or gravity-feeding medium cracks. Moisture insensitive, it can go down on damp substrates with no standing water, and it is listed for USDA facilities and NSF/ANSI 61 drinking-water contact. Typical work includes slab coatings, mortar repairs with kiln-dried sand, and hardened-to-hardened concrete bonds.

Key Features

Moisture insensitive for damp concrete with no standing water
Self-leveling medium viscosity for gravity-feed crack work

Frequently Asked Questions

Can Crackbond 2100 MV bond fresh concrete to hardened concrete?
Yes. Crackbond 2100 MV is a high-strength medium-viscosity epoxy for bonding fresh concrete to hardened concrete and steel, and hardened concrete to hardened concrete. That bonding use is why it sits on repair pours and overlays.

Is Crackbond 2100 MV moisture insensitive on damp concrete?
Yes, on damp concrete with no standing water. Crackbond 2100 MV is a moisture-insensitive epoxy. Standing water is still a stop. Dry enough for a bond, damp enough that a moisture-insensitive epoxy is the right call.

Does Crackbond 2100 MV have NSF drinking-water listings?
Crackbond 2100 MV is certified to NSF/ANSI 61 and 372 as a drinking-water system component, including the lead-free 372 listing. That is why it is used on potable-water related concrete work that also needs a medium-viscosity bonder.

Can Crackbond 2100 MV gravity-feed horizontal cracks?
Yes. Medium viscosity is the reason Crackbond 2100 MV is used to gravity-feed medium to large horizontal cracks. Super-low-viscosity injection resins are a different product family. Keep 2100 MV on the medium-viscosity bond-and-coat work.

What temperature window does Crackbond 2100 MV list?
Crackbond 2100 MV places between 40F and 100F. Crackbond 2100 MV-LPL is the slower, warmer-weather cousin on the same family sheet. This SKU is MV, so stay in the 40F to 100F MV window.

Can Crackbond 2100 MV be mixed with kiln-dried sand for spall repair?
Yes. Mixed with dried silica sand, Crackbond 2100 MV becomes a mortar for concrete and spall repair. The neat epoxy remains a bonder, coating, and gravity-feed resin. Sand is a field mortar option, not a different product.
