Nickel Composites –
The Apticote 460 family of coatings add the protective benefits of low friction polymers to the natural hardness and corrosion resistance of nickel. When applied to any ferrous alloy (including stainless steel), copper alloys, aluminium alloys or titanium, Apticote 460 coatings impart particularly high levels of wear resistance, permanent lubricity and non-stick properties. Investing in Apticote 460 coatings can add considerable value to your product and, in many cases, enable you to reduce costs.

Excellent mould-release and non-stick properties
Apticote 460’s polymer infused surface prevents substances from sticking including adhesives and glues. Most substances such as plastics and rubber will release easily.
High hardness and superior adhesive wear resistance
Apticote 460 low friction coatings achieve four times the adhesive wear resistance of electroless nickel in pin-on-disc sliding tests, with hardness values in the range 750-1000 Hv. Since the outer surface is a polymer, Apticote 460 coatings are not suitable for harsh abrasion situations.
The surface of Apticote 460 is smooth and slippery, using low friction polymers. In many cases, static friction is decreased (as low as 0.06) as the load is increased, thus eliminating “stick-slip” and undesirable vibration. For non-stick, mould-release applications, Apticote 460 utilises polymers with low surface energy.
Depending on the formulation, Apticote 460 exceeds 1500 hours in salt mist tests, and demonstrates greatly improved corrosion resistance over standard electroless nickel plating. Apticote 460 also exhibits significant resistance to many commonly used chemicals.
Applied thickness of 12 - 50 microns
The nickel composite coating is applied to a high degree of accuracy up to 50μm with no post plating finishing necessary.
USDA and FDA approved
Whilst the FDA no longer formally approves specific coatings, Apticote 460 Nickel composite solutions use a combination of materials and polymers which are FDA approved, meaning the final coating is complaint with FDA regulations.
Food production moulds
Apticote 460 can be applied to a wide range of base materials, including aluminium, steels (including stainless steels), copper alloys and titanium. Finished tolerances and surface finish are normally related to the conditions of components before processing. Some post heat-treatment is often required and may involve temperatures up to 400°C, depending on material and parameters.
Apticote 460 coatings will operate from -115°C to 260°C, depending on the formulation.
Apticote 460 can also substantially cut costs by opening up profitable new materials options. For example, a part manufactured from low carbon steel protected by the appropriate Apticote 460 corrosion resisting coating can often replace a more expensive alloy metal component, and with better performance.
GENERAL MAGNAPLATE NEDOX
Apticote 460 is offered in partnership with General Magnaplate and is also known as Nedox. Poeton are the only UK licensees of Magnaplate’s Nedox coatings. The Poeton – General Magnaplate relationship stretches back over 30 years in which time treatment solutions and expertise have been shared in order to provide the complete range of surface coatings to customers on both sides of the Atlantic.
