- Features
- In addition to improving the chemical performance of resin systems, ceramic particle loading significantly enhances the dynamic mechanical performance of the resin system.
- Total performance characteristics of CeRam-Kote 54®, both chemical and mechanical, are significantly better than liquid epoxy, fusion-bond epoxy and other high performance coating systems.
- CeRam-Kote 54® protects by binding ceramic particles to a unique resin system, thus creating an encapsulating ceramic shell. Each ceramic particle is resin coated and becomes tightly packed in the cured film.
- The compact density of the cured film of CeRam-Kote 54® yields dynamic intangible benefits such as:
- High surface lubricity producing a lower drag coefficient on a variety of surfaces, and
- Extraordinary sliding abrasion resistance providing protection against the forces of erosion/corrosion and abrasion

- Number Of Coats
Recommended two coats (each coat 4½-6 mils, 112½-150 microns)
- Dry Film Thickness
CeRam-Kote 54® should be applied holiday-free at a minimum of 10 mils (250 microns) with a maximum thickness of 15 mils (375 microns).
- Cure Time
A film of 7-10 mils DFT (175-250 microns) air dries to a touch-dry finish within three (3) hours at 72°F (22.2°C) and dries to a 70% cure in twelve (12) hours. 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
Coating performance is proportional to the degree of surface preparation. Abrasive cleaning is the most effective and economical method.
- Iron & Steel – Remove all loose rust, dirt, moisture, grease and soluble salts from surface. 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 2-2.5 mil (50-62.5 microns) anchor profile. Surface preparation should be no less than a near white (NACE 2, SSPC-SP10, Swedish Standards SA 2½) finish.
- Aluminum – Remove all oil, grease, dirt, oxide, soluble salts, and other foreign material by solvent cleaning per SSPC-SP1. Specifications call for a white metal (NACE 1, SSPC-SP5, Swedish Standards SA-3) finish with a 2-2.5 mil (50-62.5 microns) anchor profile. Surface preparation should be no less than a near white (NACE 2, SSPC-SP10, Swedish Standards SA 2½) finish.
- Galvanized Steel – Allow to weather a minimum of six months prior to coating. Remove all oil, grease, dirt, oxide, soluble salts, and other foreign material by solvent cleaning per SSPC-SP1 (recommended solvent is VM&P Naptha). When weathering is not possible or the surface has been treated with chromates or silicates, first solvent clean per SSPC-SP1 and apply a test patch. Allow CeRam-Kote® 54 to dry at least one week before testing adhesion. If adhesion is poor, brush blasting per SSPC-SP7 is necessary to remove these treatments. Ceram-Kote Coatings, Inc.• P.O.

- Fiberglass & Composites - When preparing old or previously used fiberglass or plastic material, it is important to clean the substrate to ensure all contaminants are removed before abrading. Ceram-Kote recommends hot water pressure washing (at least 3,000 psi) using trisodium phosphate or detergent. Allow to dry. Rough up or abrade with 40-grit to 80-grit sandpaper. If fiberglass is previously coated with Ceram-Kote, abrade with 100-grit sandpaper (as in section 6.0). For new fiberglass, clean and wipe all surfaces with Acetone or Methyl Ethyl Ketone (MEK) prior to profiling to remove mold release agents, wax and contamination prior to abrading. Fiberglass and composite materials must have a water content of less than 5%.
- Mixing Ratio
- Twelve (12) parts of Part A to one (1) part of Part B by volume
- Twenty and one-half (20.5) parts of Part A to one (1) part of Part B by weight
- Mixing
CeRam-Kote 54® contains a high loading of ceramic particles which must be placed into full suspension with the resin prior to application. CeRam-Kote 54® 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 with a paddle mixer 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 54® 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 stir until both parts are thoroughly mixed: QUART CAN OR SINGLE LITER MIXING: (when mixing quart or single liter cans only, pour Part A into Part B. Use this procedure for quarts or single liters only due to the small amount of curing agent in the Part B can). Stirring time is temperature dependent, but a two (2) to four (4) minute stir at 72°F (22.2°C) should thoroughly mix the components.
- Pot Life
Pot life for CeRam-Kote 54® at 72°F (22.2°C) is approximately four (4) to six (6) hours. Colder temperatures will increase the pot life and warmer temperatures will decrease the pot life.
- Thinning
Adjust viscosity with small amounts of MEK, Acetone, or Toluene. We recommend thinning to a maximum of 15% by volume.
- Application
Recommended application equipment (equivalent equipment may be substituted):
Airless Spray:
Pressure=2,800-3,000 psi
Hose 3/8" ID
Tip 0.021" to 0.027
Filter 30 mesh
Reduction = as needed up to 10% by volume
Reduction = as needed up to 15% by volumeConventional Spray:
Gun Binks 2001 or similar
Fluid Nozzle = 68 (2.8 mm orifice size)
Air Nozzle = 68PB
Atomization Pressure = 40 psi
Fluid Pressure 30 psiBrush:
Natural bristle
Reduction = Not recommendedRoller
Cover 4" lambs wool
Reduction = Not recommendedDamp or oil contaminated surfaces should always be brushed, rolled or spray and backroll applied, working the paint film into contamination.
All other surfaces - spray apply for best results using conventional, airless, or cup gun. The air source must be dry. The compressed air source should be outfitted with air dryers as needed to supply moisturefree air. After thoroughly mixing CeRam-Kote® 54, strain it with a standard paint strainer and pour CeRam-Kote® 54 into the spray equipment.Performance Tips: Stripe coat all crevices, welds and sharp angles to prevent early failure in these areas. When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. Whenever possible, cross spray at a right angle. Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profile, roughness or porosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions and excessive film build. Excessive reduction of material can affect film build, appearance, and adhesion. In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with CeRam-Kote® Thinner 1 or CeRam-Kote® Thinner 3. Do not apply the material beyond recommended pot life. Do not mix previously catalyzed material with new.
- Climate
Use CeRam-Kote 54® 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 54® will not cure or perform properly.
- Holiday Detection
CeRam-Kote 54® is classified as a thin-film coating and should be tested for defects and holidays using a 67½ volt, wet sponge spark detector set at 80,000 ohms resistance, such as a Tinker and Rasor model M-1.
- 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.
