The ROKIDE® Spray System is unique because it utilizes ceramic oxide rods. The rods are melted in a patented spray unit which projects the fully molten particles onto the substrate. The ROKIDE® particles cannot leave the spray unit until fully molten. These particles have high kinetic energy and high thermal mass, so they remain molten until they reach the substrate. ROKIDE® coatings have higher particle-to-particle cohesive bonding. Powder systems, by contrast, project smaller particles into a high-temperature gas stream and the lower dwell time does not allow all the powder particles to melt completely. The deposit efficiency of the ROKIDE® system is not dependent on the thickness of the coating. Therefore, thicker coatings -- greater than .030 inch (.8 mm) -- if required, can be applied without a reduction in deposit efficiency or quality.
