Potable Water Safe Epoxy Coating for Corrosion Resistance - CeRam Kote 426

$246.25
SKU CK426-1G.

CeRam-Kote 426 is a high-performance, spray-applied, and air-dried ceramic epoxy coating engineered specifically for potable water applications. This advanced coating provides exceptional corrosion protection in highly aggressive environments, ensuring the integrity and safety of potable water systems.

Key Features:

  • Potable Water Safe: The Water Quality Association tested and certified it (2014) to NSF/ANSI 61 section 5, making it safe for use in potable water systems.
  • Superior Corrosion Protection: The highly modified epoxy resin system is loaded with a unique package of ceramic particles, offering enhanced performance in extreme conditions.
  • Durable and Long-Lasting: The ceramic particles within the epoxy resin provide a tough, non-shrinking surface that withstands harsh environments and extends the lifespan of the coated structures.

Applications:

  • Potable Water Tanks: This ensures drinking water storage systems' long-lasting protection and safety. It is recommended for tanks 200 gallons or greater. 
  • Piping: Ideal for 24" or larger diameter pipes
  • Water Treatment Facilities: Ideal for coating pipes, tanks, and other equipment in water treatment plants to prevent corrosion and contamination.
  • Municipal Water Systems: Protects infrastructure within municipal water distribution systems, ensuring reliable water delivery.

Benefits:

  • Enhanced Performance: The unique blend of ceramic particles and epoxy resin delivers superior resistance to corrosion and chemical attacks, making it suitable for the most demanding applications.
  • Cost-Effective: By extending the life of water system components, CeRam-Kote 426 reduces maintenance and replacement costs, offering long-term savings.

Coverage:
~170 SF/Gallon - 2 coats are recommended

SHIPPING MAP

NUMBER OF COATS

Two Coats (each coat 8-10 mils, 200-250 microns)

CERAM-KOTE 426 MIXING INSTRUCTIONS:

Two (2) parts of Part A to one (1) part of Part B by volume

Two (2) parts of Part A to one (1) part of Part B by weight

CeRam-Kote 426 ceramic particles must be placed into full suspension with the resin prior to application.

CeRam-Kote 426 is packaged in two cans, Part A (resin and ceramics) and Part B (curing agent). Shake Part A (coating) with a Cyclone air-powered shaker or mix Part A until all ceramic powders are suspended in the resin. Time required to place ceramics into suspension varies according to temperature and length of material storage time. 

At 72°F (22.2°C), generally a four (4) to six (6) minute shake will place the ceramic powders into suspension. Regardless of time needed, shake all ceramic material into suspension prior to proceeding. Failure to properly mix will keep CeRam-Kote® 426 from performing or curing properly. Check the can to assure all solids are in suspension prior to proceeding to the mixing step.

Combine Part A (coating) and Part B (curing agent) and shake again until both parts are thoroughly mixed (when mixing quart cans only, pour Part A into Part B. Shaking time is temperature dependent, but a two (2) to four (4) minute shake at 72°F (22.2°C) should thoroughly mix the components. However, caution must be used to prevent heat buildup. No induction time is needed before application

CURE TIME

After thoroughly stirring CeRam-Kote® 426, strain it with a standard paint strainer and pour CeRamKote® 426 into the spray equipment. Apply a first pass of eight (8) to ten (10) mils (200-250 microns) WFT. At 72°F (22.2°C), 30-40 minutes is sufficient time for waiting for first pass to set. Apply a second pass of eight (8) to ten (10) mils (200- 250 microns) for a total DFT of sixteen (16) to twenty (20) mils (400-500 microns) DFT. 

Cure time is temperature dependent. Apply additional mils without incurring runs or sags if the finished product requires thicker coverage. Whenever possible, apply second coat in a cross-coat method.

SURFACE PREP

Bonding strength depends on proper preparation of the surface to be protected for long-term performance of the product. The substrate should be free of oil, grease and salt/chloride contamination. Specifications call for a white metal (NACE 1, SSPC-SP5, Swedish Standards SA-3) finish with a 1-2.5 mil (25-62.5 microns) anchor profile. Surface preparation should be no less than a near white (NACE 2, SSPC-SP10, Swedish Standards SA 2½) finish. 

Cleanliness is the most important step to produce a coated surface that will perform and last. Call CERAM-KOTE® COATINGS INCORPORATED for surface preparation recommendations of materials such as aluminum, brass, plastic, fiberglass and/or concrete.

THINNING:

Thinning of CeramKote 426 is not recommended

APPLICATION: 

Barrier Application

An airless sprayer with a minimum 33:1 ratio is recommened. The air source must be dry. Use reversible carbide tip with orifice size of 0.019-0.021 inches. If applying with roller, use short nap, such as 1/4” (.244 mm). Brush application is also an option.

After thoroughly stirring CeRam-Kote® 426, strain it with a standard paint strainer and pour CeRamKote® 426 into the spray equipment.

Apply a first pass of eight (8) to ten (10) mils (200-250 microns) WFT. At 72°F (22.2°C), 30-40 minutes is sufficient time for waiting for first pass to set. Apply a second pass of eight (8) to ten (10) mils (200- 250 microns) for a total DFT of sixteen (16) to twenty (20) mils (400-500 microns) DFT. Cure time is temperature dependent.

Apply additional mils without incurring runs or sags if the finished product requires thicker coverage. Whenever possible, apply second coat in a cross-coat method.

When using for potable water:

Max Use temperature = 23°C
Max Product Surface Area/Water Volume Application, cm2 /L = 67.7 For use with 200 gallon tanks or greater and pipe diameter of 24” or greater, not exceeding a surface area to volume ratio of 67.7 cm2 /L

Climate:

Use CeRam-Kote 426 only if the substrate temperature and ambient air temperature is above 40°F (4.4°C). No coating should be permitted when substrate is wet from rain or dew, when surfaces are less than five degrees Fahrenheit (three degrees Celsius) above the dew point and holding or when relative humidity is greater than 85%. Moisture will inhibit the catalyst reaction and CeRam-Kote® 426 will not cure or perform properly.

Holiday Detection:

This product is classified as a thin-film coating and should be tested for defects and holidays using a high voltage holiday detector.

Repairs:

If application of the coating is less than seventy-two (72) hours old and has not been exposed to contamination, repair by wiping with Acetone or MEK and then re-apply CeRam-Kote 426. If contaminated or more than 72 hours old, first sand with appropriate grit sandpaper, then repeat repair process.

Cleanup:

Purge and clean spray equipment within thirty (30) minutes of the final spray. Flush equipment with Acetone or MEK until solvent sprays clear. Disassemble and clean equipment to manufacturer’s recommendations. Material left in spray equipment will solidify and damage equipment. Use precautionary measure applicable to any catalyzed material.

Cleanup:

See individual product label for safety and health data. A Material Safety Data Sheet is available upon request.

Purge and clean spray equipment within thirty (30) minutes of the final spray. Flush equipment with Acetone or MEK until solvent sprays clear. Disassemble and clean equipment to manufacturer’s recommendations. Material left in spray equipment will solidify and damage equipment. Use precautionary measure applicable to any catalyzed material

STORAGE & SHELF LIFE

Pot life for CeRam-Kote® 426 at 72°F (22.2°C) is approximately 30 minutes. Colder temperatures will increase the pot life and warmer temperatures will decrease the pot life. Keep cans out of direct sunlight to prevent heat buildup.

CeRam-Kote 426 has an indefinite shelf life. Preferred storage/usage is a dry enclosed area under 85°F (29°C) /used within two (2) years. However, if stored more than two years above 85°F (29°C), call CERAM-KOTE® COATINGS INCORPORATED technical support prior to use
