PRODUCT DATA SHEET: CERAM-KOTE ORGANIC ZINC PRIMER
Description: CeRam-Kote Organic Zinc Primer is a high solids zinc rich epoxy primer for protection of structural steel in salt or
weathering environments that will be topcoated with CeRam-Kote products. Not recommended for immersion service.
Available in green only.
CeRam-Kote Organic Zinc Primer is 78% total zinc in the dry film. The primer offers excellent adhesion and undercutting
resistance. The material is prethinned and ready to spray upon mixing. CeRam-Kote Organic Zinc Primer meets most VOC
(Volatile Organic Compound) regulations.
Suggested Uses: Structural Steel and Equipment
TECHNICAL DATA
Volume Solids: 82% +/- 2%
VOC: 3.75 lb/gal (4.49 g/l)
Number of Coats: One Coat (2-4 mils WFT, 50-100 microns)
Dry Film Thickness: CeRam-Kote Organic Zinc Primer should be applied at a preferred thickness of 1-3 mils (25-75
microns) DFT. Dry film thickness in excess of 8 mils (200 microns) per coat is not recommended.
Excessive film thickness may increase damage during shipping or erection.
Coverage: Theoretical coverage is 1027 mil ft2 (25.5 m2/l at 25 microns); 342 ft2 at 3 mils (8.4 m2/l at 75 microns).
Mixing and application losses will vary and must be taken into consideration when estimating job
requirements.
Cure Time: A one coat film of 1-3 mils (25-75 microns) DFT air dries to a film set in 4.5 hours at 77°F (25°C).
Film set time is 20 hours at 40°F (4.4°C). Coating should be fully cured in 2-7 days.Cure times lengthen
at lower temperatures and shorten at higher temperatures. If the coating is to be exposed to a critical
service environment, coating should be fully cured before placing into service.
Surface Preparation: Bonding strength depends on proper preparation of the surface to be protected for long-term
performance of the product. The specification is 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 Freecom for surface
preparation recommendations of materials such as aluminum, brass, plastic, fiberglass and/or concrete.
Mixing Ratio: One (1) part of Part A to one (1) part of Part B. Part C is pre-measured.
Mixing: CeRam-Kote Organic Zinc Primer is packaged in three parts: Part A (Base), Part B (Curing Agent) and
Part C (Zinc Dust). Add Part B into Part A (Part A is very thick and Part B is very thin). Mix for
approximately one (1) to two (2) minutes. Slowly add Zinc Dust to mix until all zinc is mixed
thoroughly. Spray CeRam-Kote Organic Zinc Primer immediately after mixing to assure solids are in
suspension (settling of zinc occurs immediately).
Packaging: CeRam-Kote Organic Zinc Primer is available in one (1) gallon and two-and-one-half (2-½) gallon kits.
Pot Life & Shelf Life: Pot life for CeRam-Kote Organic Zinc Primer is one (1) hour at 75°F (24°C) and less at higher
temperatures. It is recommended that CeRam-Kote Organic Zinc Primer be used within one (1) year of
delivery.
Thinning: Not required.

Application: Spray apply using conventional, airless, HVLP or cup gun. The air source must be dry. The
compressed air source should be outfitted with air dryers as needed to supply moisture-free air. Use
pressure feed equipment such as high volume, low pressure equipment or Binks 2001 spray equipment
with a 563CVT needle, 63CVT fluid nozzle and 63PB air nozzle. Airless: use reversible carbide tip
with orifice size of 0.019-0.021 inches. Do not apply CeRam-Kote Organic Zinc Primer by roller.
After thoroughly shaking CeRam-Kote Organic Zinc Primer, strain it with a standard paint strainer and
pour CeRam-Kote Organic Zinc Primer into the spray equipment.
Apply a coat of two (2) to four (4) mils (50-100 microns) WFT and allow sufficient time for solvent to
flash off. At 72°F (22.2°C), 30-40 minutes is sufficient. 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.
Climate: Use CeRam-Kote Organic Zinc Primer only if the substrate temperature and ambient air temperature are
above 40°F (4.4°C). No coating should be permitted when substrate is wet from rain or dew, when
surfaces are less than 5°F (3°C) above the dew point and holding or when relative humidity is greater
than 85%. Moisture will inhibit the catalyst reaction and CeRam-Kote Organic Zinc Primer will not
cure or perform properly.
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, MEK or Isopropanol (99% pure) and then re-apply
CeRam-Kote Organic Zinc Primer. If contaminated or more than 72 hours old, first sand with
appropriate grit sandpaper, then repeat repair process. Touch-up by roller is not recommended. Use
brush for touch-up of small areas only. Use medium bristle brush for applying full strokes. Avoid
rebrushing.
Cleanup: Purge and clean spray equipment within thirty (30) minutes of the final spray. Flush equipment with
Acetone, MEK or Isopropanol (99% pure) 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.
Safety: See individual product label for safety and health data. A Material Safety Data Sheet is available upon
request.
