Foundry & Refractory

We are delivering defect-free foundry and ceramic coating performance with advanced additives and functional microsphere technology.

The Foundry coatings and ceramic coatings play a critical role in achieving clean cast surfaces, controlled heat transfer, smooth release, and consistent finishing quality. In real production conditions, coatings must perform reliably under high temperatures, thermal shock, abrasion, chemical exposure, and continuous mixing/shear. 

Even small process variations can create costly defects such as pinholes, craters, foaming marks, rough surface finish, uneven film build, poor wetting, settling, viscosity drift, or inconsistent release. These issues can lead to rework, higher rejection rates, metal penetration, reduced casting quality, and productivity losses.

Geocon Group supports foundries and ceramic coating formulators with a focused portfolio of performance materials that improve lubricity and release, density control, thermal barrier contribution, dispersion quality, and foam stability. Our offering includes Boron Nitride, Ceramic Microspheres, Glass Microspheres, Wetting Agents, and Defoamers—selected to help you achieve stable coating systems, consistent film build, improved surface finish, and reliable performance across demanding foundry and ceramic operations.
