NSP 120 is a two component blend of high performance epoxy resins and hardeners and offers a solvent free coating
system with virtually no odor. This product provides excellent chemical and abrasion resistance. Outstanding features
include high film build in one coat application, 100% solids (NO V.O.C.), and quick turnaround which significantly
reduces downtime.
Approvals: Certified under NSF Standard 61 for use in potable water tanks larger than 1,000 gallons and pipelines
larger than 16 inches.
Authorized by USDA for use in Federally Inspected meat and poultry plants where there is a possibility
of incidental food contact.

LIMITATIONS
PREPARATION
STORAGE
Surface must be clean of oils, grease, biological growth, loose rust and other loose contaminants.
For Potable Water Storage Tanks: Steel - Preclean according to SSPC-SP1 as required. Suitable methods of precleaning
include high pressure water blasting, steam cleaning or solvent washing followed by wiping with dry, clean rags. Prior
to abrasive blasting, grind smooth all weld seams, sharp edges, weld spatter, pitted or irregular surfaces. All surfaces
to be coated should be abrasive blasted in accordance with SSPC-SP10 or NACE 2, Near White Metal Blast Finish.
Abrasive Media should be selected to achieve an anchor pattern of 2.0 to 3.0 mils. If salt contamination is suspected,
clean substrate using liquid soluble salt remover according to the manufacturers directions. It is strongly recommended
that all surfaces be blasted and coated in the same day to prevent possible flash rusting.
Concrete - Substrate to be coated should receive a sweep or brush blast cleaning (SSPC-SP7) to remove sharp edges,
laitance or foreign matter and to provide an anchor pattern for adhesion. Abrasive blast media should be selected to
product a rough texture similar to 80-100 grit sandpaper. A combination of 40/60 mesh size is recommended to avoid
damage to sound substrate while still opening cavities or ‘bugholes.’ Nozzle pressure should be approx. 50-60 psig.
Immediately prior to coating, the entire area should be cleaned and vacuumed free of all loose matter, blast media, dust
or other contaminants. All standing water should be removed prior to coating; however concrete may be in a damp or
moist condition. The final prepared surface shall have a pH of between 5 and 10 as determined by the use of pH paper.
Best if not applied below 50°F (10°C) or if the dew point is within 5° of the temperature. All application and surface
preparation should be consistent with good painting practices.
This is a two component system. Thoroughly blend 2 parts base to 1 part curing agent using a power agitator for 3-5
minutes. To ensure complete mixing, scrape sides and bottom of containers. Incomplete mixing will result in soft spots
or color variation. Begin application immediately after mixing.
First Coat - Apply one coat of NSP 120 coating at 4-8 mils by brush, or 1/4” nap phenolic core roller at 12-20 mils, or
airless spray at 4-20 mils. Allow this first coat to cure a minimum of 12 hours at 77°F before proceeding to finish coat.
If a second coat is applied care should be taken to avoid any contamination between coats. Allow to cure a minimum
of 2 days before returning to service. Airless application - see 45:1 ratio pump: .023” - .027” orifice tip; use 3/8”
material hose unless more than 50 ft. is needed, then use 1/2” material hose.
Call Progressive Epoxy Polymers for NSF 61 restrictions/requirements.
When applying NSP 120 in cooler temperatures (500°F - 60°F) and high humidity, it is necessary to watch for the
formation of an amine blush. This blush may appear as a milky white residue on the surface of the cured coating, but
will not effect the integrity of the film. However, blush must be removed by solvent wipe before the application of
another coat or an intercoat adhesion problem will occur.
