SPRAY COATING POWDER AND METHOD OF FORMING THE SPRAY COATING POWDER AND METHOD OF FORMING A COATING LAYER USING THE SPARY COATING POWDER, AND SPRAY COATING LAYER FORMED WITH THE SPRAY COATING POWDER

摘要

A powder for spray coating, a method for preparing the powder, and a method for preparing a spray coated film by using the powder are provided to improve adhesion, to inhibit the generation of impurities and to prevent the effect of a preform. A powder for spray coating comprises a silicon carbide particle; a silicon particle; a dispersant; and an alcohol-based solvent or an aqueous solvent. The silicon carbide particle has a diameter of 100-1,000 nm, the silicon particle provides the binding force between the silicon carbide particles and has a diameter of 0.5-10 mum, and the dispersant disperses the silicon carbide particles and the silicon particles uniformly.
