Yes, mostly for prototyping & other low volume applications. Please contact us if you are interested in our coating services.
The coating is applied using a solvent-based specialty chemical paint formulation that contains ceramic additives in a polymeric precursor solution. The recommended process for coating application is by spray (Spray Can Application Instructions), however, other methods including dip or brush-on are suitable for certain substrate geometries and applications. Please Contact Us for more information on bulk paint sales suitable for large scale production.
For a 25 µm thick coating, large scale surface roughness will be dictated by the substrate surface quality. Fine scale roughness can be further refined with 600 grit silicon carbide paper.
Our team will work closely with you to set up the design for large scale production at your plant (or third party) and supply paint at large quantities under a relatively simple sales agreement. Contact Us for more details.
Yes, Cerablak® HTP-100 coated materials have been validated for outstanding protective performance in oxidizing, ultra-high vacuum, and hydrogen/natural gas environments. The inert nature of the coating combined with outstanding diffusion barrier characteristics are the key differentiating features compared to our competition.
Our standard recommended dry film thickness (DFT) for the coating is 25-50 µm (0.001-0.002”).
Substrate cleanliness is the most critical factor for ensuring that the paint bonds directly with the substrate. In case of coating re-application, ensure there is no residual corrosion scale remaining on the substrate prior to paint application. Maintaining appropriate distance of the spray gun from substrate and spraying with uniform translation rate at recommended dwell times between spray passes will help achieve uniform coverage and thickness. Please see our How to Apply page for more details.
Standard QC methods include thickness measurement (eddy current probe), scratch and hardness testing (ASTM D3363), tape adhesion testing (ASTM D3359-17), and electrical insulation testing (ASTM D149). More extensive evaluation can include thermal shock resistance (ASTM D2485-18) or extended oxidation/environmental exposures similar to the service environment.
Cerablak® HTP 100 has been applied to a broad range of ferrous, non-ferrous alloys, including various grades of steel, aluminum, advanced nickel-based alloys, and ceramic substrates. The coating is designed with engineered porosity to impart compliance/low modulus such that thermal mismatch stresses are accommodated for a wide variety of substrates.
Cerablak® HTP 100 is an All-Purpose ceramic coating for use on metals, alloys, ceramics/refractories, and composites for protection in harsh service environments up to 1800°F (982°C).
Please see Application Instructions. In general, the coated part needs to be dried up to 250°F to remove the solvent carrier in the paint, then subjected to temperatures up to 570°F for 5 minutes, ramping up at 20°F/min. IR lamps, heat guns, and kilns can all be used to cure the coating.
For a fully cured coating, light grit blast is the most efficient way to remove the coating.
Heat cleaning removes organic debris and promotes chemical bonding with the substrate for excellent adhesion at room and elevated temperatures. If the substrate is sensitive to heat cleaning in air (e.g., copper), use inert atmospheres for heat cleaning or attempt heat cleaning at temperatures lower than onset of corrosive scaling. For curing the coating, maintain ramp rates < 20°F/min to avoid premature substrate oxidation prior to full conversion to ceramic composite coating.
We recommend either a light grit blast or abrasion with Scotch Brite™ Red, followed by degreasing with acetone and heat cleaning (between 300-480 °F for 5 minutes). No separate primer or bondcoat is required for any substrate type.
