GP-200
Grey Ceramic Microspheres
High-strength, fine particle alumino-silicate ceramic microspheres engineered for mechanical integrity, dimensional stability, and superior durability in demanding industrial formulations.
GP-200 GREY CERAMIC MICROSPHERES
GP-200 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, GP-200 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 GP-200 particularly effective in industrial coatings, oil & gas systems, construction materials, and composite formulations where performance outweighs aesthetic whiteness.
With a median particle size (D50) of just 7 µm, GP-200 provides excellent packing efficiency and film build in high-solids formulations — enabling higher filler loadings with minimal viscosity penalty compared to irregular mineral fillers such as silica or kaolin.

APPLICATIONS OF GP-200
GP-200's combination of fine particle size, high compressive strength, and spherical morphology makes it the preferred ceramic filler across demanding industrial sectors where mechanical performance is paramount.
High-Solids Industrial Coatings
Improves packing efficiency and film build in epoxy/PU/acrylic industrial coatings, enabling higher solids with controlled viscosity and robust mechanical performance.
Anti-Corrosion & Marine Coatings
Enhances abrasion resistance and coating integrity in protective primers/topcoats, supporting tougher films and improved durability in harsh marine environments.
Industrial Flooring & Heavy Toppings
Acts as a rigid ceramic microfiller in epoxy/PU floors and screeds to improve wear resistance, compressive strength, and long-term surface durability.
Cementitious Repair Mortars & Grouts
Provides micro-reinforcement and dimensional stability in repair systems, helping reduce cracking and improving mechanical strength under load.
Oil & Gas Cementing
Suitable for mechanically demanding cementing and wellbore strengthening formulations where particle integrity and stability are required under pressure and temperature.
Thermoset Composites
Improves stiffness and dimensional stability in epoxy/polyester/ vinyl ester composite matrices, supporting better mechanical performance versus irregular mineral fillers.
Foundry & Refractory Coatings
Improves thermal stability, erosion resistance, and surface integrity in refractory and foundry coatings exposed to high temperatures and molten metals.
Automotive & Engineering Coatings
Used in underbody, chassis, and component coatings to enhance durability, stone-chip resistance, and long-term mechanical stability in automotive applications.
Adhesives & Structural Sealants
Acts as a rigid microfiller to improve mechanical strength, gap stability, and creep resistance in epoxy and PU-based structural bonding systems.
Polymer-Modified Concrete & Overlays
Improves load-bearing capacity and abrasion resistance in polymer-modified concrete, overlays, and industrial repair layers.
Tooling, Mold & Die Coatings
Enhances wear resistance and surface hardness in mold and die coatings, helping reduce metal pick-up, surface damage, and maintenance frequency.
Wear-Resistant Linings & Barriers
Incorporated into protective linings for chutes, hoppers, and material-handling equipment to improve resistance to abrasion and mechanical wear.
KEY BENEFITS OF GP-200
High Compressive & Impact Resistance
High-strength ceramic shells contribute to improved mechanical performance under static and dynamic loads — significantly better than soft mineral extenders.
Improved Dimensional Stability
Rigid ceramic structure minimizes shrinkage, cracking, and deformation in thick-section and load-bearing applications, ensuring long-term part integrity.
High Build Capability
Supports rapid thickness build in coatings, mortars, and flooring systems without excessive viscosity increase or sagging — ideal for high-solid formulations.
Efficient Particle Packing
Spherical morphology improves packing efficiency, reducing segregation and improving uniformity — enabling higher filler loadings with less binder demand.
Thermal & Chemical Resistance
Stable above 1,000°C and resistant to acids, alkalis, and hydrocarbons — suitable for harsh industrial environments and oilfield applications.
Non-Combustible & Inert
Inorganic ceramic composition ensures fire safety and long-term stability with no chemical interaction with resins, binders, or curing agents.
Effective Density Contribution
Controlled spherical ceramic particles provide reinforcement while contributing predictable and measurable density in high-volume structural systems.
Cost-Performance Optimisation
Enables partial replacement of heavier, costlier mineral fillers and aggregates while achieving or improving required strength and volume properties.
