Functional perfluoropolyethers
Fomblin® Functional perfluoropolyethers can react with conventional polymeric materials to impart to them the specific properties of the perfluoropolyether chain. They can be active ingredients of stable water-based microemulsions commonly used as surface treatment to convey mold release and anti-sticking properties.
Structure
Fomblin® Functional PFPEs are characterized by a perfluoropolyether backbone and functional end-groups (Hydroxylic group, Urethane methacryate, TriEthoxySilane) having different molecular weights.
Performance
Fomblin® Functionals PFPEs can react with conventional polymeric materials with the aim to impart to them the specific properties of the perfluoropolyether chain such as:
- Chemical resistance
- Low surface energy
- Water and oil repellency
- Anti-sticking properties
- Low refractive index
- Boundary lubrication
Applications
Special Surface Treatment: Building Block, CVD, UV-Curable Coatings, others.
Fomblin® PFPE derivatives (Fomblin® ZDOL with MW from 2000 up to 4000, Fomblin® MD40 etc.) are particularly refined functional grades for high end applications which require high fluorine content and high bifunctionality (e.g. lubrication for HD drives, low RI coating, etc.).
Magnetic Recording Media Lubricants
Fomblin® Z PFPE derivatives are well know lubricants for the Magnetic Recording Media industry. They are used as top lubricants on the HD drive surface to prevent damaged on the disk surface.
