INOMETA PROTEK - Thermal Sprayed Ceramic Coatings

Thermal sprayed ceramic coatings are specialized coatings made of ceramic materials. These coatings are applied to surfaces such as CFRP/GFRP rollers or aluminium components to protect them from extreme temperatures and/or abrasive environments.

Our PROTEK ceramic coatings made of titanium, aluminium, and chromium oxides are particularly resistant to frictional and sliding wear, offering outstanding wear protection when guiding films, fibers, paper, and cardboard. Defined surface structures ensure reliable entrainment and air removal, while ground coatings achieve optimal sliding properties. In addition, hydrophilic or hydrophobic properties can be realized depending on the processing stage.
By using advanced processes and high-quality materials tailored to your specific requirements, we ensure optimum performance and reliability for your application.

Specially developed for a wide range of industries, our PROTEK^® ceramic coatings offer first-class protection and functionality. Through our dedication to quality and innovation, we collaborate with you to develop customized solutions that perfectly meet your specific needs and propel your business forward. Our PROTEK^® ceramic coatings are used in a wide range of applications, including:

• Printing industry – base layer of anilox rollers in flexographic and gravure printing processes
• Textile industry – dry lead rollers
• Film industry – laminating rollers, corona rollers
• Printing industry – doctor blades
• Steel industry – rollers & slewing bearings, continuous casting molds
• Chemical industry – pumps, agitators, plain bearings
