Spray-On Protective Coatings

For automotive paint, ceramic spray coatings are popular for their gloss and protection. Parkway-Kew specializes in industrial thermal spray coatings, such as tungsten carbide and nickel chrome, engineered for heavy-duty machine components rather than automotive paint protection.

Consumer spray sealants offer temporary protection against dirt and UV exposure on painted surfaces. For industrial applications requiring wear and corrosion resistance under extreme mechanical stress, engineered thermal spray coatings like HVOF and plasma-applied ceramics deliver significantly more durable and reliable protection.

High Velocity Oxygen Fuel (HVOF) coating sprays powdered material at speeds exceeding Mach 2 onto a component's surface, creating a dense, low-porosity coating with excellent adhesion. Parkway-Kew has used HVOF since 1989 to apply tungsten carbide and nickel chrome coatings for superior wear resistance.

Coating lifespan depends on the material, application, and operating conditions. Tungsten carbide HVOF coatings on fracking plungers and wire drawing blocks can significantly outlast uncoated components, while proprietary processes like Restore & Grind allow multiple cost-effective repairs before a full recoat is needed.

Yes, worn wire drawing blocks can typically be recoated rather than replaced. Parkway-Kew's Restore & Grind process fills and blends the drawline wear area, enabling 5-7 lower-cost repairs before a full recoating is required, extending block life well beyond the original coating.

Oil and gas, wire drawing, shipping terminal operations, and heavy equipment manufacturing benefit significantly from thermal spray coatings. These industries rely on components like fracking plungers, wire drawing blocks, festoon wheels, and rope pulleys that require enhanced wear and corrosion resistance under demanding conditions.
