Ingro-653

DESCRIPTION:

AT-INGRO (UW) 653 is a moisture insensitive liquid which is epoxy based and solvent free. It is specially recommended for concrete repair in damp, wet and under-water conditions. After the components are mixed well, the liquid is injected in concrete cracks; it becomes a very rigid and high strength material and results in solving the problem. STANDARDS: It complies with ASTM C881 – 87, Grade I, Class B + C

USES:

  • AT-INGRO (UW) 653 is used to fill and seal cavities and cracks in structural components such as:
    • Columns
    • Machine bases
    • Beams
    • Foundations
    • Decks
    • Water Retaining Structures

ADVANTAGES:

  • AT-INGRO (UW) 653 is a deeply penetrative liquid with high adhesive qualities. Other benefits are:
    • Solvent Free
    • Suitable for both DRY & DAMP conditions
    • Usable at low temperatures
    • Shrinkage free hardening

INSTRUCTION FOR USE:

  • SURFACE PREPARATION
    • Crack surfaces must be clean, free from standing water and all loosely adhering particles, cement laitance and foreign particles should be removed.
  • MIXING
    • Mix both the components together in right proportion for at least 2 minutes with a recommended stirrer and electric hand drill at a slow speed (max 600 rpm) until smooth consistency and homogeneous mixture of uniform colour is achieved.
    • Proper care has to be taken so that no air is entrapped due to mixing.
  • APPLICATION METHOD
    • Various application methods are practiced with different equipment requirement, depending on the nature of the work to be carried out.
    • Generally used automated inject equipment or manual method.
    • Set appropriate injection ports based on system used. Inject AT-INGRO (UW) 653 with steady pressure after adhesive seal has cured.

INSTRUCTION FOR USE:

  • IMPORTANT RECOMMENDATIONS
    • Minimum and Maximum crack width for application: 0.1 & 4.0 mm respectively.
    • Minimum age of new concrete : 3-6 weeks
    • Not to be injected under hydrostatic pressure
  • CLEANING
    • All tools and equipment should be cleaned immediately after use. Hardened / cured material can only be mechanically removed.
