- Surface Preparation & Application
Surface Preparation
Steel – Immersion Service: SSPC-SP10 Near White Blast Cleaning with 3.0-mil profile Non-Immersion Service: SSPC-SP6 Commercial Blast Cleaning with 2.0 mil profile Non-Immersion Service where a Commercial Blast Cleaning cannot be performed: Minimum requirement is SSPC-SP 2/SSPC-SP 3 Hand/Power Tool Cleaning or SSPC-SP7 Brush Off Blast Cleaning Concrete – Concrete must be properly cured for a minimum of 28 days before application of coating. Surface must be entirely free of oil, grease, dirt, detergent, surface water, laitance, curing compounds, coatings or other contaminants that may interfere with adhesion. The concrete must be abrasive or water blasted to provide an anchor pattern (similar to 60-80 grit sandpaper min.) for adhesion. Final prepared surface should be clean and rough. Consult SSPC-SP13 – Surface Preparation of Concrete.
Mixing Instructions
This is a two-component system. Prior to mixing, components A Resin and B Hardener should be at room temperature (60-75 F/16-24C). Pour Part B Hardener into Part A Resin. Mix for 3 minutes using a Jiffy mixer head and a mechanical drill. To ensure complete mixing, scrape sides and bottom of container and continue mixing for an additional 1 or 2 minutes. Do not mix more material than can be applied within the pot life. Do not hand mix. Begin application immediately – no induction time.
Mixed Ratio - 2 Parts A (Resin)1 Part B (Hardener) by volumeApplication
- Air and surface temperature should be between 40-125F. Do not begin application if air, substrate or material temperature is below 40F or expected to fall below 40F within 12 hours of application. Do not begin application if dew point is within 5F/3C of the temperature. Variations in temperature can affect pot life and sag properties of this material. Do not exceed 20% by volume of thinner with NSP-T1 Thinner. NSP-T1 Thinner will not clean hoses or equipment adequately. Clean up using Acetone or other Ketone Solvent. For concrete surfaces, a primer coat of either NSP 100, 101 and 110 is strongly recommended.
- Air and substrate temperatures - Elevated ambient and substrate temperatures during application (90-125 Deg. F) can affect the application properties in the following ways: speed up reaction time between Part A Resin and Part B Hardener therefore shortening pot life and decreasing drying times, lowering the viscosity of the product therefore decreasing sag resistance on a vertical surface. As long as the applicator knows pot life will be decreased and sag resistance (lower film build in one coat) on vertical surfaces will decrease, it will not have any negative effects on the cured film.
- Excellent chemical resistance – Crude oil, sour gas, chlorine, bleach, Sulfuric Acid 0-70% Sodium Hydroxide 0-50% in immersion service, ambient temps
Method of Application: Brush, Phenolic Core Roller, Airless Spray
Recommended Equipment
Airless Spray Pump – a minimum of 30:1 – preferred 45:1 Tip Range - .023 to .027 Hose – 3/8” I.D. if less than 50 ft. – greater than 50 ft. use 1/2” (3500 psi High Pressure Spray Hose) Pressure (in) 90 cfm minimum @100 psi Pressure at the tip – increase pressure slowly to 2000 psi and fine tune to achieve proper spray pattern. Check condition of fan at spray tip. During the first seconds of spraying, the material will often finger. Raise or lower pressure to adjust width. Periodically check pressure gages while spraying. Knowing operating pressure will be useful in analyzing any changes to your spray pattern. Whip – 3’- 5’ and 1/4” ID Hose Take care to prevent mixed material from setting up in hoses. For optimum results, keep hose as short as possible, out of direct sunlight or away from heat. Purge immediately after spraying with Acetone or Ketone solvent. Cured material must be mechanically removed.
- Limitations
- This product may not cure properly in temperatures below 40 F All epoxies will show chalking/yellowing on exterior exposures. Application of epoxy coatings in cool temperatures and high humidity can result in the formation of amine blush. Blush may appear as a milky, white, tacky residue on the surface of the cured coating and must be removed before the application of another coat.
- Intercoat adhesion problems may occur if blush is not removed.
