GP200 Grey Ceramic Microspheres are high-strength, fine particle ceramic microspheres manufactured from alumino-silicate ceramic compositions, designed for applications where mechanical integrity, dimensional stability, and durability are critical.
Unlike lightweight hollow grades used primarily for density reduction, GP200 is engineered to deliver higher compressive strength and abrasion resistance, making it suitable for structural, protective, and load-bearing formulations. The grey coloration and controlled particle size distribution make GP200 particularly effective in industrial coatings, oil & gas systems, construction materials, and composite formulations, where performance outweighs aesthetic whiteness.

Ceramic microspheres are high-heat stable upto 1200–1400 °C
Improves packing efficiency and film build in epoxy/PU/acrylic industrial coatings, enabling higher solids with controlled viscosity and robust mechanical performance.
Enhances abrasion resistance and coating integrity in protective primers/topcoats, supporting tougher films and improved durability in harsh service environments.
Acts as a rigid ceramic microfiller in epoxy/PU floors and screeds to improve wear resistance, compressive strength, and long-term surface durability.
Provides micro-reinforcement and dimensional stability in repair systems, helping reduce cracking and improving mechanical strength under load.
Suitable for mechanically demanding cementing and strengthening formulations where particle integrity and stability are required under pressure and temperature.
Improves stiffness and dimensional stability in composite matrices, supporting better mechanical performance and processability versus irregular mineral fillers.
Improves thermal stability, erosion resistance, and surface integrity in refractory and foundry coatings exposed to high temperatures and molten metals.
Enhances wear resistance and surface hardness in mold and die coatings, helping reduce metal pick-up, surface damage, and maintenance frequency.
Acts as a rigid microfiller to improve mechanical strength, gap stability, and creep resistance in epoxy and PU-based structural bonding systems.
Improves load-bearing capacity and abrasion resistance in polymer-modified concrete, overlays, and industrial repair layers.
Used in underbody, chassis, and component coatings to enhance durability, stone-chip resistance, and long-term mechanical stability.
Incorporated into protective linings for chutes, hoppers, and material-handling equipment to improve resistance to abrasion and mechanical wear.

Coarse, spherical ceramic particles enable lightweight formulations while maintaining structural integrity, ideal for thick and high-volume systems.
Supports rapid thickness build in coatings, mortars, and flooring systems without excessive viscosity increase or sagging.
Rigid ceramic structure helps minimize shrinkage, cracking, and deformation in thick-section and load-bearing applications.
High-strength ceramic shells contribute to improved mechanical performance under static and dynamic loads.
Spherical morphology improves packing efficiency, reducing segregation and improving uniformity in coarse-filled systems.
Stable at elevated temperatures and resistant to acids, alkalis, and hydrocarbons, making it suitable for harsh industrial and oilfield environments.
Inorganic ceramic composition ensures fire safety and long-term stability without chemical interaction with binders.
Allows partial replacement of heavier mineral fillers and aggregates while achieving required strength and volume, improving overall formulation economics.
