Corrosion is responsible for billions spent on maintenance and replacement costs. General solutions provide limited corrosion resistance however our coatings provide the next step forward in corrosion protection.
Corrosion protection can be done in a number of ways: 1. sacrifical coatings, 2. barrier coatings or 3. a combnation of the two. For example our Zinc-Aluminium flake coating is sacrificial but also has a barrier element. Teflon based coating tend to be more barrier type coatings.
Zinc-Aluminium Flake Coatings
Zn-Al flake coatings have the advantage of a thin layer (8 – 12 µm) but with a salt spray corrosion resistance to white rust in excess of 720 hrs and more than 1000 hrs to red rust. Our 213 Zn-Al flake coatings easily outperforms galvanizing, E-coat, electroplated zinc and cadmium plating. It can be applied to many different parts including fasteners requiring better-than-normal corrosion resistance. The friction coefficient of 213 an also be adjusted to the customers requirement. 213 has no harmful substances such as chrome or lead. The Zn-Al flake coatings are now specified by several car companies. Zn-Al coatings are also specified under properietary names such as Geomet, Magni, Dacromet or Delta.
The most well-known barrier coating is Gunkote. The TDCC can apply the SCK and 16/2 range. SCK is typically for military applications whereas the versatile 16/2 range can be applied in many applications ranging from machine components to fasteners, and is available in a range of colours. For example, salt spray tested 16/2 coated fasteners show no signs of corrosion after 2000 hrs of exposure. The TDCC is an authorized applicator of Gun-Kote.
Dry Film Lubricant
Certain applications call for dry lubrication (i.e.the absence of oils or greases ) to decrease friction and to prevent seizing. Dry Lube coatings incorporate a lubricating solid such as Molybdenum Disulphide, Graphite, Boron Nitrite or PTFE (Teflon). The most common dry film coatings incorporate Molybdenum Disulphide (MoS2) which show a friction coefficient of less than 0.1. Please enquire with us about your specific application.
Non-stick coatings are found on applications ranging from cookware to industrial valves to injection moulding dies. These coatings commonly contain PTFE (Teflon) and other release agents. In addition to release properties the coatings also provide good corrosion resistance plus good lubricity. Please speak to us about your exact requirement. The range of non-stick coatings is vast!
Other Specialized Coatings
We can offer many other surface protection coatings. From acid resistant coatings used in mining to electrically conductive coatings for non-static applications to high temperature coatings. Please contact us about your requirements.
