PRODUCT DESCRIPTION
NCL EPOXY EP800-I is a two part, low viscosity epoxy resin for sealing of fine cracks and repairing of cracked concrete to restore the structural strength. The cured NCL Epoxy EP800-I entirely and completely restores the concrete to its original monolithic conditions. NCL EPOXY EP800-I is supplied in two bulk containers for use together with two-component injection machine or pressure grout pump.
COMPOSITION
NCL EPOXY EP800-I is a Two-part Injection Resin which consists of Part A – Resin/Base and Part B – Hardener. Part A and Part B are mixed to form high-strength rigid epoxy resin.

INJECTION PROCESS
Single-line Injection Process:
Mix homogeneously Part A and Part B in 2:1 ratio by volume in a suitable clean and dry container. Inject mixed resin with single-line injection machine. Ensure resin is injected within the pot life of the material after mixing.
Twin-line Injection Process:
Feed twin-line injection machine (2:1 ratio by volume) with Part A and Part B separately. Inject material through the injection gun equipped with static mixer into structure to be sealed.
FINAL PRODUCT
Once mixed, the injection material cures to rigid and tough resin in concrete structure and completely restores the concrete to its monolithic condition.
