THE COATING
Black Knight 1000 is a resin bonded lubricant coating system, specially formulated to provide dry-film lubrication and corrosion protection to metallic fasteners, fittings and castings across a wide range of industrial applications, including but not restricted to the water and mining industries. The Black Knight 1000 Coating System consists of a series of coating processes, including a thorough cleaning and metallic conversion pre-treatment and a heat cured Fluoropolymer top coat containing PTFE, which when combined with a meticulous application procedure produces an anti-corrosive, low friction coating which will enhance the performance of any metallic product.
All products in the Black Knight Coatings range are applied in our purpose designed coating facility, which is capable of processing high and low volume orders with its industry renowned and recognised quality and service. All orders are quality checked at every stage of the process to ensure the job is done right the first time. Written procedures are followed by our staff and written records are kept which are annually and independently audited, to make certain that our quality system operates to the highest of industry standards.
FASTENERS
The Black Knight 1000 Coating System when applied to a high tensile fastener provides a superior and more cost affective alternative to using Stainless Steel or Galvanising. A Black Knight fastener is superior, in that it contains a dry-film lubricant which completely eliminates any chance of galling of the threads, therefore making installation and removal almost effortless in comparison to Stainless or Galvanised fasteners. Unlike galvanising, Black Knight fasteners do not require overtapped nuts, due to the coatings low film build, which is a significant time and cost saving on it’s own. When provided with a sample of a Black Knight 1000 coated bolt and nut, people are surprised with the ease of which the nut glides up and down the thread.
The Black Knight 1000 coating system can also be used over stainless steel for extreme environments in particularly areas of high chlorites, which will not only extend the service of life of the product, but will also eliminate any galling or seizing of the threads which is a common problem with stainless steel fasteners.
