Unifrax Fiberfrax® Topcoat™ 3000 Coating Cement

Fiberfrax Topcoat™ 3000 and Topcoat™ M coating cements have a temperature grade rating of 1538°C (2800°F). Topcoat 3000 consists of a blend of regular ceramic fibers and high-temperature Fibermax® polycrystalline fibers combined with an inorganic binder system. This product imparts excellent flame and hot gas erosion resistance to other product forms and effectively minimizes thermal shrinkage of fiber blankets, modules, and boards. Topcoat M is a blend of Fibermax fibers in a dry powder form which is mixed with a prescribed amount of potable water at the job site. It provides protection against slag and alkali attack when applied to Fiberfrax high-temperature boards and modules.Typical ApplicationsProtect high-temperature Fiberfrax lining systems from slag and alkali attackImprove hot gas erosion resistance of Fiberfrax high-temperature liningsReduce thermal shrinkage of hot face in high-temperature refractory and ceramic fiber liningsFill hot face surface cracksInformation Provided by Unifrax I LLC
