Cerablak

Cerablak® HTS represents a revolutionary advancement in the sealing of materials with fine open porosity. Gaseous or vapor ingress into fine pores have plagued the performance of materials such as refractories for many decades and the problem is growing as temperatures are being increased in industrial applications. With Cerablak® HTS comes an elegant solution, resolving sealing issues in a wide range of porous materials, including refractories, advanced ceramics and composites, and thick ceramic coatings.

Cerablak® HTP is a high-emissivity spray-on coating that provides thermal insulation and environmental protection. Utilizing a conventional off-the-shelf spray gun and a proprietary slurry feedstock solution, Cerablak® HTP is deposited as an inorganic coating with a brief thermal treatment after deposition. The black version of Cerablak® HTP is particularly unique in blocking radiant heat. Thermal conduction by radiation becomes critical above 700°C and Cerablak® HTP can provide durable thermal protection in oxidizing, reducing, and even vacuum environments such as in semiconductor manufacturing or space exploration.
