Main features of the spin coater uses
Spin coater is a solution-based process used for the fabrication of thin films, in the thickness range from micrometre to nanometre, to deposit uniform coating of organic materials on flat surfaces.
The substrate is mounted on a chuck that rotates the sample, creating centrifugal force which drives the liquid outwards. Then, the thin film is deposited by evaporation of the liquid. The machines carrying out this series of processes are spin coaters.

Spin Coater Natural Polypropylene
POLOs Series uses High Grade Natural Polypropylene (NPP-H), with α-crystalline properties as housing material for the spin coaters and chucks. This material offers more rigidness and toughness than other derived materials as well as an increased life-span and higher chemical and stress-crack resistance, improving from normal polypropylene.
This material also offers benefits to the system operations, with an acceleration of 0-12.000 rpm in 3 seconds, an accuracy of 0.1 rpm, and a substrate size which can vary from 5 nm to 450 nm.
Not only does NPP-H offer the wide variety of benefits already listed but it can be used in the vast majority of applications and is a much more economical option than other possibilities as PTFE. Moreover, the chemical compatibility of High Grade NPP is graded mostly with an excellent rate with the materials used for coating, the same that PFTE.
For those exceptional applications that require PTFE, TFMTM 1600 is used, which offers a better chemical absorption rate than standard PTFE.
