Gullon is a two-step process that combines our Armoloy TDC with PTFE (polytetrafluoroethylene) polymers to produce an inherently lubricated wear surface. Covering and surrounding the rounded or nodular microscopic spheres or our TDC, lubricant in the form of a PTFE polymer keeps the surface extremely slick and creates an ideal wear interface. Used in non-lubricated wear application or in applications in which wear components cannot be serviced or replaced for long periods of use, Gullon has proven to be an exceptional product.
Hardness - The polymer topcoat is quite soft and typically wipes soon after actuation or initiation of service of the process part leaving the 78Rc nodular wear surface with trapped PTFE particles to act as the wear interface.
Surface Finish - The appearance of the processed part will be that of a smooth, coated part and can be provided in several colors with black and blue the most common choice. Once placed in service, and the PTFE top coat has been wiped, the surface retains the PTFE particles even though the Armoloy wear surface is visible.
The dense nature of the Armoloy coating means high corrosion resistance as the coating is almost free of micro-cracks (conventional chrome +/- 40 micro-cracks per cm2)
Absolute adhesion - Armoloy® coating will not chip, flake, crack, peel or separate from the base metal under standard ASTM bend tests or under conditions of extreme heat or cold.
Uniform deposits without thickness or edge build-up or "dog-boning" associated with conventional chrome-plating processes.
No requirement for post finishing (except special applications)
Gullon is very slippery, very hard and resistant to most industrial corrosive environments.
Typical Thickness - The standard deposit thickness of Armoloy TDC ranges between .0005" - .0008" with a tolerance range of +/- .00005".
