Specializing in refractory solutions, Refratek is bringing its complete portfolio to Metalurgia, highlighting two innovations that combine practicality, efficiency and sustainability: Castek Isothermix and Castek Colamica. Castek Isothermix is a lightweight mortar with thermal, acoustic and flame retardant properties, developed for use on walls, slabs and partitions. Its versatility allows it to be used in both industrial and urban environments, providing comfort, energy efficiency and fire protection.
Among the most important differentials of this refractory solution are the effective insulation that reduces heat exchange and improves the performance of air conditioning systems, the energy savings that reduce the need for cooling or heating and the fire resistance that increases safety in installations that require flameproof barriers. The low density (0.61 g/cm³) makes the material light and easy to handle. What’s more, application is simplified by simply adding water to the preparation. As it is a non-toxic formulation, it reinforces Refratek’s commitment to developing sustainable solutions.
These characteristics make the product ideal for use in construction, laboratories, industries and environments that need thermal and acoustic insulation combined with fire safety.
CASTEK COLAMICA REFRACTORY SOLUTION TECHNOLOGY
Refratek’s second launch at Metalurgia is Castek Colamica, an inorganic refractory adhesive specially developed for bonding mica and refractory accessories. Its properties guarantee high performance in high-use environments, as it is resistant to temperatures of up to 1600 °C and cures quickly, in less than an hour, which speeds up repairs and maintenance. The organic-free formulation provides stability and safety and the quality finish is essential in highly demanding processes.
These differentials enable Castek Colamica to be widely used in sectors such as foundries, steel, cement, glass, ceramics and other industries that depend on severe thermal systems. Its application guarantees less waste, greater reliability and durability in operations.
