Mastik

Mastik is a high-temperature refractory sealing compound used for patching, repairing, and sealing furnaces, ladles, tundishes, and other refractory linings. Developed by Cast Chem Technology, it is specially formulated to withstand thermal shock, high temperatures, and mechanical abrasion commonly encountered in metal melting and holding operations.

Its ready-to-use paste-like consistency ensures easy application and excellent adhesion to a variety of refractory and metal surfaces. Mastik is designed for quick-drying and strong bonding, reducing downtime and improving safety in foundry environments. It is suitable for both temporary and permanent repair applications in aluminum and other non-ferrous metal industries.
