Crackbond LR-321 Epoxy Injection Resin 15.9 oz Cart

Crackbond LR321 Injection Resin is a two component, 2:1 ratio, 100% solids,high modulus, structural epoxy adhesive. It is a solvent free, low odor, high strength, moisture insensitive, low viscosity epoxy system. Crackbond LR321 is formulated for use as an injection resin for cracks in structural concrete, masonry & wood. It’s also perfect for epoxy grouting, healing-sealing or as a mortar when mixed with sand. It has the viscosity of light oil and low surface tension, allowing it to deeply penetrate fine cracks. It cures to a solid with no shrinkage, bonds to both surfaces of the crack, bonding the structure back to its original monolithic strength. Crackbond LR321 can be used at temperatures between 40°F – 110°F, providing contractors with a choice for injecting cracks in high and low temperature environments. In addition, Crackbond LR321 has a viscosity of 450 cps which is ideal for gravity feed crack injection applications. Crackbond LR321 is an excellent choice where a high strength adhesive with maximum field reliability is desired.

CRACKBOND LR-321 has been approved under Florida Department of Transportation (FDOT) SpecificationSection 926 Epoxy Crack Injection Type E. It is listed on their Approved Products List (APL)
