High Temperature Refractory Coatings | |
|
Aremco’s refractory paints provide high temperature protection of crucibles, molds and structures used in the processing of metals, glasses and plastics. | |
|
Graphi-Coat™ 623 |
This coating system, originally patented by Aremco, is a two-part, silica-bonded, titanium diboride filled, oxidation resistant coating for protecting graphite from oxidation to 2000 °F (1093 °C). Used on graphite crucibles, heat-treating fixtures, and electrodes in the metallurgical industry. |
|
Pyro-Paint™ 634-AS, |
These alumina-silica based advanced coatings are rated for continuous service temperatures up to 2300 °F (1260 °C). Provides excellent adhesion to ceramic fiber blankets, modules and boards and resists wetting by nonferrous molten metals, increasing the durability and erosion resistance of the underlying material. High dry film thicknesses from 10-50 mils can be achieved with this coating. Select 634-AS for thin coating applications and 634-AS1 for high build applications. |
|
Pyro-Paint™ 634-AS1 | |
|
Pyro-Paint™ 634-AL |
This pure, alumina based compound creates a high temperature resistant coating for refractory fiber boards and shapes, providing exceptional resistance to molten metals and open flames to 3200 °F (1760 °C). Increases heat reflectivity in furnaces to improve efficiency and ramp up temperatures more rapidly. |
|
Pyro-Paint™ 634-ALP |
This phosphate-bonded, alumina coating system bonds exceptionally well to dense refractory ceramics, providing high abrasion and corrosion resistance for operating temperatures to 3200 °F (1760 °C). |
|
Pyro-Paint™ 634-BN, |
These highly-filled boron nitride solutions are extremely lubricious and inert, and are non-wetted by molten salts, glasses, plastics, and most metals including aluminum and magnesium. |
|
Pyro-Paint™ 634-BNSC | |
|
Pyro-Paint™ 634-CA, |
These carbon and graphite based coatings are formulated for parting of aluminum permanent molds, non-sticking in glass forming applications, and lubrication and stopoff in metalworking and wire drawing. Provides superior release, surface finish and mold protection. |
|
Pyro-Paint™ 634-GR | |
|
Pyro-Paint™ 634-SIC |
This advanced silicon carbide, water-based coating reduces significantly the oxidation of graphite and carbon components and structures at temperatures to 2550 °F (1400 °C). Provides a hard surface and withstands thermal cycling. |
|
Pyro-Paint™ 634-YO |
This ultra high temperature yttrium oxide coating provides exceptional protection of graphite, ceramic and metal components exposed to reactive molten metals such as titanium, uranium and their alloys. Usable in vacuum and inert atmospheres to 2732 °F (1500 °C). |
|
Pyro-Paint™ 634-ZO |
This highly-filled zirconium oxide-based coating produces a hard, chemically-resistant protective layer which is stable with aluminum, molybdenum, platinum, rhodium, and titanium. It is ideal for sealing porous ceramics and protecting other ceramic, graphite and metal structures up to 3270 °F (1800 °C). Exceptional for coating resistance wire heating elements in furnaces, protecting them from residue buildup which causes arcing and reduced element life. |
