Abstract
Silicon carbide particles coated with a pigmented coating result in silicon carbide particles which can be used in slip resistant flooring to achieve the desired slip resistance whilst giving improved aesthetic properties. The pigmented coating can be an organic coating such as a two part epoxy system or a water based or solvent based epoxy. Alternatively the pigmented coating can be an inorganic coating such as a ceramic glaze. Also provided are methods of coating silicon carbide particles with either an organic or an inorganic pigmented coating. Further provided are safety flooring materials including silicon carbide particles having a pigmented coating.
Claims23
Silicon carbide particles coated with a pigmented coating.
Particles according to any preceding claim wherein the particles are coated with a coupling agent beneath the pigmented coating to aid adhesion of the pigmented coating.
Particles according to any preceding claim wherein the particles have a size range of from 0.2 to 0.8 mm.
A method of applying an organic pigmented coating to silicon carbide particles comprising the steps of:
- mixing silicon carbide particles with a liquid pigmented organic coating system;
- curing-the coated particles.
A method of applying an inorganic pigmented coating to silicon carbide particles comprising the steps of fusing an inorganic pigmented coating onto the silicon carbide particles.
