The APTICOTE 200 range of unique 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 approval (more accurately, now quoted as ‘FDA compliance’), they are particularly suited for applications in the food and medical sectors.
Using various engineering processes, Poeton can build these benefits into ferrous and non-ferrous metals. The low friction polymer coating formulations are matched precisely to different industrial applications, guaranteeing you optimum performance at minimum cost.
Non Wetting Surface of APTICOTE 200
The six primary grades of APTICOTE 200 low friction and non-stick polymer coatings are shown below, together with their key properties
|APTICOTE 200 Grade|
|Nominal dry film thickness (µ)||20||25(c)||25||25||20||5-10|
|Deposition Temperature °C||400||370||260-345(e)||400||220-345(f)||340|
|Max in-service temperature
|For non-stick/mould release
(1 is best)
|For low friction
(1 is best)
|Sliding wear resistance (vs steel pin)
(1 is best)
|Abrasion resistance (by SiC wheel)
(1 is best)
(1 is best)
|FDA Approval (Compliance)||Yes||Yes||No||Yes||No||Yes|
(a) - Powder coating - electrostatic
(b) - 200C is generally reserved for stainless steel substrates
(c) - 200N can be built up to 50µ if the application demands additional thickness
(d) - Other colours, including black, are also possible
(e) - With 200B, the higher temperature cure gives maximum wear resistance
(f) - Optimum cure temperature for 200L is 240°C
As shown in the table above, the APTICOTE 200 polymer coating systems can offer you a wide range of performance characteristics, depending on the needs of your application.
The coatings can withstand operating temperatures in the range -200°C to +260°C. For the highest service temperatures, you should specify 200L, which can tolerate short periods at up to +285°C.
It is not usual to achieve the best mould release properties and high sliding wear resistance with the same coating. The chart above shows the performance of the various Apticote 200 grades. Non-stick is measured by the force required to separate a product (burnt rice is the most severe test) from the surface, so that a low value is best. Likewise, wear is measured by a pin-on-disc machine, low values of wear rate being the objective.
For best mould release (non-stick), for example against sticky food or pharmaceutical products (needing USDA/FDA food approval , or ‘compliance’), specify Apticote 200G or Apticote 200N. With stainless steel substrates (E.g. Stavax moulds), the clear Apticote 200C provides superb non-stick release properties in situations where FDA approval (compliance) is required.
If it's a high temperature application, Apticote 200L is the best option for working with plastics, packaging and adhesives.
If you require a degree of sliding wear resistance, then Apticote 200E (Food approved, or ‘compliant’) should be specified, but the level of non-stick and low friction will be reduced.
In sliding situations requiring a high load bearing ability, the best coatings are Apticote 200E and Apticote 200B, with the latter being cured at the highest temperature, 345oC.

| Dynamic Friction
Again, low friction and good non-stick properties do not necessarily occur together. The table shows the friction performance of the various grades in a ball-on-disc test (10N load), demonstrating that Apticote 200E and Apticote 200L coatings are the best choice for low friction sliding situations, particularly if a low wear rate is also important. Apticote 200C gives exceptional low friction and non-stick, but is relatively soft, so gives less wear protection. It should be reserved for non-abrasive situations.
Apticote 200B, 200N and 200G tend to give higher friction, but better non-stick. Apticote 200N provides the best all round performance, but Apticote 200B, with its optional lower temperature cure may be needed for temper-sensitive substrates.
If the primary requirement is that the coating should be able to withstand scratching or abrasion, as well as non-stick, (as might occur when moulds are being cleaned) the best coating to specify is Apticote 200N.
If the primary requirement is that the coating should be able to withstand chemical attack (e.g. from process fluids), as well as non-stick or low friction, the best coating to specify is Apticote 200N.
