Adhesives Technology Corp.’s new Crackbond CSR is a two-part, 100 percent solids, fast-setting urethane used to repair cracks or spalls in concrete.
The ultra-low viscosity of Crackbond CSR allows deep penetration into cracks, producing a high-strength bond. Repaired areas of high traffic can be reopened quickly as CSR boasts a cure time of less than 20 minutes and achieves strength of 4,900 psi in one hour. It is great for repairing spalled floor joints and concrete on bridge and parking decks. It is self-leveling, and the addition of aggregates can produce a mortar. It can be used in temperatures down to zero F.
