Fiberfrax^® Topcoat^™ M

Fiberfrax^® Topcoat^™ M coating cements have a temperature grade rating of 1538°C (2800°F). 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 Applications:

• Protect high-temperature Fiberfrax lining systems from slag and alkali attack
• Improve hot gas erosion resistance of Fiberfrax high temperature linings
• Reduce thermal shrinkage of hot face in high-temperature refractory and ceramic fiber linings
• Fill hot face surface cracks
