Low Friction Non-Stick Polymer Coatings
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 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 (including PTFE, FEP and PFA polymers) are matched precisely to different industrial applications, guaranteeing you optimum performance at minimum cost.

(a) - 200N can be built up to 50µ if the application demands additional thickness
(b) - 200C is reserved for stainless steel substrates only
(c) - With 200B, the higher temperature cure gives maximum wear resistance
(d) - Reserved for high temperature non-stick, e.g. rubber

Properties and Industrial Benefits
 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.
-
Working Temperatures
The coatings can withstand operating temperatures in the range -200°C to +300°C. For the highest service temperatures, you should specify Apticote 200A or 200L.
-
Non-Stick and wear Resistance
It is not usual to achieve the best mould release properties and high sliding wear resistance with the same coating. The chart above indicates the strengths of the various Apticote 200 grades. Non-stick is measured by the force required to separate a product 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 FDA food approval), specify Apticote 200G or Apticote 200N. With stainless steel substrates (Eg Stavax moulds), the clear Apticote 200C provides superb release properties in situations where FDA approval is required.
If it's a high temperature application (for example, against curing rubber) Apticote 200A is the most appropriate (but not food approved). Apticote 200L is the best option for high temperature applications other than rubber (eg plastics, packaging adhesives).
If you require a degree of sliding wear resistance, then Apticote 200E should be specified, but the level of non-stick will be reduced.
In sliding situations requiring a high load bearing ability, the best coating is Apticote 200M. The wear rate remains low under conditions where the softer Apticote 200E and Apticote 200B may give shorter lives.
-
Low Sliding Friction
Again, low sliding 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 low friction polymer is the best choice in low friction sliding situations, particularly if a low wear rate is also important. Whilst Apticote 200M gives neither the lowest wear rate nor the lowest friction, it is the obvious choice where the substrate (e.g. aluminium alloy pistons) requires a low deposition temperature.

-
Abrasion Resistance
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.
-
Chemical Resistance
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.
