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:
- NI-1054 Novolac (for chemical resistance)
- Chopped Fiberglass ( for flexibility and increased strength)
- 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.

V. ADVANTAGES AND LIMITATIONS
- Advantages
- Increased flexability
- No unpleasant odors.
- 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.
- High Chemical Resistance Base coat Hydro-Seal 75 will prevent
absorption of exterior moisture TTC-001 224.
- Base coat Hydro-Seal 75 retains ability to flex with substrate
movement passes 1/8" Mandrell Test ASTM-D-822.
- Base coat is 56% epoxy and solvent free.
- Introduction of fiberglass with chop gun increases the flexibility
of 1054R.
- Sulfuric acid rapidly oxidized samples of conventional epoxy
systems. The 1054 Novolac Epoxy system was intact after 140 days.
- 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.
- NI-1054 Novolac Epoxy resin provides low viscosity to increase
your flexibility in preparing 100% solids formulations.
- Limitations
- Should not be applied over prior paints or coatings.

- CHEMICAL STRUCTURE
- The improved performance of NI-1054 Novolac Epoxy can be directly
linked to its chemical structure.
- 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
- 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.
- Prime Coat and Second Coat
- Coverage: approximately 100-150 sq. ft. per gallon
- Tools: 3/8" nap roller, tray
- Procedure
- Mixing Hydro-Seal 75
- Mixing Ratio (1-1)
- Do not mix more material than can be applied within 40
minutes at 72 degrees F.

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.
- Metal surfaces: should be prepared with a solution of phosphoric acid and neutralized with water
- Concrete surfaces cement block, poured concrete
- New
- Should be at least 30 days cured, prior
to application of seamless flooring materials and free of sealers,
curing compounds (silicon hardeners), oil, grease, paint, hydrostatic
pressure and moisture transmission.
- Should be smooth and level
- Old
- Must be clean, free of paint, stain or
other foreign material that would prevent proper hydration and bonding.
- Patching and Leveling deteriorated and cracked surfaces: use Northern
Industries Epoxy Mortar System
- Thickness
- Under 1/4": Straight Epoxy Mortar System
- Mixing Ratio by volume: Three (3) parts cement to one (1)
part mixed Hydro-Seal 75 Epoxy
- Over 1/4": Add fine sand to Epoxy
Mortar System to eliminate cracking.
- Mixing Ratio by volume: More sand is needed for thicker
applications. Up to a ratio of: 3 parts sand, 1 part cement, 1
part mixed Hydro-Seal 75 for 1/2 " to 3/4" patch.
- Tools ( and additional materials):
- a straightedge trowel or wide putty knife
- Portland Cement
- fine sand if needed
- Procedure:
- Fill and smooth all cracks with Mortar System as a
scrape and seal coat
- Prepare rough, porous or contaminated surfaces that
are deteriorating by filling and repair them with the Epoxy
Mortar System.
- Dry (1) hour at 70 degrees F and 50% humidity.
- Other Surfaces: Wood substrate should be exterior grade
plywood. Particle board should meet requirements of FHA use of
materials bulletin UM 28 A.
- Prepare seams, joints, and Nail Holes by using the
following method: Skim coat seams/joints and Nail Holes with
Northern Epoxy Mortar System and then Lay 4" fiberglass tape
over mortared seams/joints.
- Tools
- 4" Wide straight edge Putty Knife or straight edge trowel
- Portland Cement
- 4" Northern fiberglass tape
- Mixing Ratio: 2 parts cement, 1 part mixed Hydro-Seal 75
- Procedure
- Apply Epoxy Mortar System over joints as smoothly as possible (feather edging)
- Lay Northern Industries fiberglass tape into the mortared joints.
- Apply additional Epoxy Mortar over fiberglass tape as smoothly as possible (Feather edging)
- Fill all nail holes with same mixture
