Polymer Coatings –
Apticote 200
The Apticote 200 range of polymer coatings comprises high technology polymer-based formulations offering outstanding non-stick, mould release, low friction and low wear properties. They also provide superior chemical corrosion protection, even in the most hostile environments. And with full FDA compliance, Apticote 200 Polymer coatings are particularly suited for applications in the food and medical sectors.
Dry film lubricant solutions are comprised of very small particles of lubricating agents mixed with a binding resin. The coating is then cured to bond the surface to the substrate.
Poeton’s extensive range of dry film lubricant treatments are tailored to provide a range of industrial applications and are commonly used in applications where liquid lubricants would be unsuitable.
options
apticote 200B
Combines non-stick and low wear, with a low curing temperature possible.
apticote 200E/S
Best wear resistance and low friction.
apticote 200L
Highest temperature applications.
apticote 200C
Clear coating giving the best non-stick in medial application with FDA compliance.
APTICOTE 200G
Superb non-stick in food applications
(FDA compliance).
apticote 200N
Tough, food release and FDA compliant.
Key Features
Low friction
Coefficients of friction as low as 0.08 in steel pin vs rotating disc scenarios.
Abrasive wear
Apticote 200 can resist abrasive wear by aggressive products such as a filled polymer or gritty food product.
Mould release
Apticote 200 is highly adept at releasing a whole variety of products from their mould tools/dies, from injection moulded polymers and composite materials, through to food stuffs and food packaging products.
Heat resistance
The coatings can withstand operating temperatures in the range -200°C to +260°C. For the highest service temperatures, we would recommend Apticote 200L, which can tolerate short periods at up to 285°C.
Non-wetting
The structure of Apticote 200 coatings create surface conditions where liquids naturally bead up preventing surface wetting.
FDA compliance
Whilst the FDA no longer formally approves specific coatings, several of the Apticote 200 polymer solutions use a combination of materials which are FDA approved, meaning the final coating is complaint with FDA regulations.
Chemical resistance
Whilst aggressive chemicals such as solvents and alkaline cleaning fluids can soften or degrade polymers, the Apticote 200 range includes solutions that resist these effects. A thick coating of Apticote 200N with 100% coverage will also provide the best corrosion resistance to substrates.
APPLICATIONS
Hydraulic shafts and pneumatic arms
Moulds and press tools
Machine tool slideways
Compressor cylinders
Valves and pumps

Notes
(a) Powder coating – electrostatic
(b) 200C is generally reserved for stainless steel substrates
(c) 200N can be built up to 50µm if application demands additional thickness
(d) Other colours, including black, are also possible
(e) With 200B, higher temperature cure gives maximum wear resistance
(f) Optimum cure temperature for 200L is 240°C
