Providing aluminum alloys with durability, lubricity, and 15,000+ hours salt spray resistance
Technical Data Sheet - AnoLube III-15K
Anoplate’s AnoLube III - 15k represents a breakthrough in hard anodic protective coating for aluminum alloys used in extreme environments. Using sequentially-applied inorganic, bi-metallic sealant, followed by a proprietary, chemicallybonded fluoropolymer, the aluminum surface is imparted with enhanced surface properties such as:
Key Advantages
- Low coefficient of friction, non-stick PTFE
surface - Low wettability = easy clean-ability
- Abrasion-resistant, “file hard” ceramic
- Chemically-inert fluoropolymer impregnation
- Corrosion-resistant anodize
- High Dialectric Withstanding Voltage
AnoLube III - 15k is a synergistic coating that utilizes the strengths of both coatings to provide a single coating system that is better than either of the two alone. AnoLube III - 15k penetrates in to the surface, so it will never chip, blister or peel.
AnoLube III - 15k utilizes a proprietary PTFE lubricant, its hydrophobicity rendering the coated part easily cleanable.
Anoplate has the capability and experience to mask off holes, recesses, tight-fits, or any other features that cannot receive the thickness afforded by AnoLube III - 15k.
Under this proprietary process, a speciallyformulated fluoropolymer penetrates the surface of a precision-hardcoat anodized component. The result is a highly-corrosion resistant ceramic which exhibits dielectric properties superior to that of conventional hardcoat anodize. Additionally, the coating retains its non-stick, low-coefficient of friction properties afforded it by PTFE.

Key Considerations
Anoplate’s AnoLube III - 15k typically involves 2-mils (50 microns) of coating thickness. Because the anodize is grown from the aluminum substrate, roughly half of that coating thickness penetrates in to the original dimension, so the measurable dimensional change on a 2-mil coating is approximately 1 mil.
Deposit hardness is impacted by the alloy used. AnoLube III - 15k can be applied to sand and die-cast alloys, but coating hardness, corrosion and wear resistance are best when the substrate is a wrought alloy.
While AnoLube III - 15k significantly improves the coefficient of friction versus the un-coated substrate, surface finish has an even more significant impact on slip performance.
