Ceramic Microspheres
High Performance Abrasion Resistance
3M solid ceramic microspheres are used as an additive in coating and polymer formulations. Due to their high hardness and spherical morphology they offer outstanding abrasion, scratch and burnish resistance.
Ceramic microspheres are used in various thermoplastics and thermosets to improve the strength, toughness and durability of the composite. Their spherical nature eases constraints on loading levels and improves processability.
Being composed of an alkali alumino silicate means that they are UV transparent down to 250 nm, allowing them to be easily incorporated into UV curing systems.
