– Apticote 350

350 - Hard Anodising Polymer Composite

The Apticote 350 Hard Anodising Polymer Composite range combines the hardness of aluminium oxide with the lubrication, wear resistance and corrosion protection of fluorocarbon polymers. The polymer is permanently locked within the structure of the newly formed hard anodised layer, resulting in a hard, continuously lubricating polymer/ceramic surface.

The hard anodising coating is combined with micro-scale polymer pigments ensuring that the polymer is absorbs deep into the anodising layer. Combining this with our high accurate chemistry along with the professional laboratory, skilled operators and comprehensive quality inspections ensure that our Apticote 350 hard anodised polymer coating.

Key Features

Extremely low friction

Apticote 350 composite hard anodised coatings are invaluable in an un-lubricated situation with a coefficient of friction as low as 0.10. The dispersion of polymer within the layer gives low friction throughout the component life, reduces wear on the counter face, and decreases frictional heating.

High hardness

The hard anodising process transforms the surface into aluminium oxide with a base hardness of over 2500Hv. However, the open structure of micropores means the measured hardness is around 400 to 500Hv and is not influenced by the polymer content. The purest alloys give the highest hardness as elements such as copper and silicon cause additional porosity.

Very low wear

Hard anodising polymer coatings provide superb wear protection in sliding and adhesive wear situations. Apticote 350 is ideal for slideways, bearings and calibrators, where low stick-slip is required.

Excellent corrosion protection

Apticote 350 maximises the corrosion protection by combining a hard anodic layer with an anti-corrosion seal and an additional polymer barrier. For these benefits plus FDA approval, see our Apticote 356 variant.

Superb control of coating thickness

The Apticote process employs special jigging and power supplies to allow for thicker coatings of up to 75 microns.

Uniform coverage

Apticote 350 hard anodising provide a completely uniform surface layer of predictable thickness. Component surface growth is approximately 50% of the total coating thickness so that final dimensions can be accurately predicted. For optimum results, sharp corners should be relieved as much as possible. This reduces the cost of machining and grinding and improved the precision of manufacture.

Non-stick / Non-wetting

Apticote 350 imparts non-stick properties, with reduced drag or torque during initial running. Polymer is also available on the surface to provide a start-up and assembly aid. The polymer is both oleophobic and hydrophobic, so the coatings repel water and oil and are self-cleaning. Apticote 350F is particularly effective in food applications.

Coats a range of aluminium alloys

AAnodising can be applied to most aluminium alloys including those most used in aerospace and defence applications – grades 2124 (T3), 7175 and 6082. Alloys with a silicon content greater than 10% or more than 5% copper are unsuitable.
