Hydro-Glass NI-1054R

I. INTRODUCTION

Hydro Glass NI-1054 Secondary Containment System was designed to withstand chemical spills of concentrated sulfuric acid, acetone, and methanol. The Containment System was formulated for on site, four coat spray or roller application, with fiberglass, that forms a positive, high quality, integral protective barrier against severe chemical penetration.

II. DESCRIPTION

This unique system combines:
  1. NI-1054 Novolac (for chemical resistance)
  2. Chopped Fiberglass ( for flexibility and increased strength)
  3. Hydro-Seal 75 Waterproofing Underlayment

III. TYPICAL USES

Hydro Glass Ni-1054 Secondary Containment System is ideal for heavy commercial and industrial areas requiring the highest level of acid and chemical resistance. It is also well suited for tank linings, seamless industrial aggregate flooring and many other civil engineering applications requiring high chemical resistance.

IV. APPLICATION AREAS

V. ADVANTAGES AND LIMITATIONS

  1. Advantages
    1. Increased flexability
    2. No unpleasant odors.
    3. USDA Approved: Hydro-Seal 75 and 1054R Novolac Epoxy resin and curing agent meet U.S. Food, Drug and Cosmetic Act Regulation 21 CFR1 75.300 when properly formulated for food contact applications.
    4. High Chemical Resistance Base coat Hydro-Seal 75 will prevent absorption of exterior moisture TTC-001 224.
    5. Base coat Hydro-Seal 75 retains ability to flex with substrate movement passes 1/8" Mandrell Test ASTM-D-822.
    6. Base coat is 56% epoxy and solvent free.
    7. Introduction of fiberglass with chop gun increases the flexibility of 1054R.
    8. Sulfuric acid rapidly oxidized samples of conventional epoxy systems. The 1054 Novolac Epoxy system was intact after 140 days.
    9. In acetone, non-post-cured conventional resin was cracked by solvent-induced swelling in one day, while NI-1054 Novolac Epoxy resin survived three days without cracking.
    10. NI-1054 Novolac Epoxy resin provides low viscosity to increase your flexibility in preparing 100% solids formulations.
  2. Limitations
    1. Should not be applied over prior paints or coatings.

  4. CHEMICAL STRUCTURE
    1. The improved performance of NI-1054 Novolac Epoxy can be directly linked to its chemical structure.
    2. In Conventional epoxy resin the isopropylidene bridge between the two phenols makes it more subject to oxidation by concentrated sulfuric acid or heat and air. But the methylene bridge in NI-1054 Novolac Epoxy allows easier rotation and lower viscosity

VII. STORAGE

Protect containers from freezing

VII. APPLICATION

  1. Surface Preparation: New concrete must be cured a minimum of 28 days, and be free of sealer, curing compounds, etc. Old concrete must be clean, and free of paints, oils, stain, or other foreign materials that would prevent proper hydration and bonding of the Hydro-Seal 75 base coat. Cracks and irregularities in the concrete can be repaired with Hydro-Seal 75 mortar mix. See Appendix A.

Appendix A : Substrate Preparation : Hydro-Glass NI-1054 Secondary Containment System

Prepare and abrade substrate removing all foreign material such as preservatives, waxes, sealers, paint, hardeners, etc.

Substrate should be wood, concrete or metal: having a true surface within 1/8 inch (+/-) 10 feet in any direction.

Substrate temperature must be no lower than 50'F and maintained during the installation and curing period.

For concrete leveling and patching use the Epoxy Mortar System (cement and Hydro-Seal 75 (a two component, water-soluble, thermoset, heavy bodied, odorless epoxy resin formulation), and fine sand for applications over 1/4" thick.

For Plywood or Particleboard installations, always use the Epoxy Mortar System and fiberglass tape for taping joints and the mortar for filling nail holes.
