CRACKBOND LR-321 CONCRETE REPAIR EPOXY 16oz.

CRACKBOND® LR-321 family products are two-component, high modulus structural epoxy formulations designed to repair cracks in concrete. Due to their ultra-low viscosities, LR-321 and LR-321LPL are perfect for gravity-feed repair of fine to medium size cracks. LR-321G, however, has a thixotropic gel-like consistency, and is ideal for medium blind-side crack repair, as it flows when under pressure and gels once injection stops. The usable temperature range is between 50 °F and 100 °F (10 °C and 38 °C).
