Issue 47/2015 - High-performance dispersions increase the added value of functional coatings

At CHINACOAT 2015, Solvay Specialty Polymers showcased high-performance perfluoropolyether (PFPE) dispersions, including Fluorolink PFPE materials, to meet the stringent requirements
of the aerospace, automotive and electronics industries for high-performance coatings.
Without significantly increasing the thickness of the coating, the material can impart special properties such as ice resistance, easy cleaning, shape retention, etc.
, to meet advanced goals
such as energy efficiency, productivity and sustainability.

Fluorolink® PFPE dispersions are ideal for surface treatment and polymer modifiers, helping to improve and increase the added value
of various properties.
They reduce the surface energy of coatings, provide excellent oil and stain repellency, and are self-lubricating for easy-to-clean, self-healing, anti-hindrance, and antifouling coatings
.
The dispersion is used in a wide range of applications, including anti-icing coatings for the aerospace industry with excellent hydrophobic properties; Automotive coatings
that look good, have good durability, are easy to clean, are oil repellent and fingerprint-proof.
In these coatings, the small amount of PFPE as a modifier can significantly reduce the surface energy
.

As bifunctional perfluorinated compounds, Fluorolink surface treatments and polymer modifiers combine the unique high-performance properties of fluorinated materials with the flexibility of reactive groups to facilitate interaction with substrates and other polymers
.
This adaptable chemical is ideal as a functional additive for polyamide, polyester, acrylic and epoxy coatings, giving them better resistance to one or more of the properties of chemical resistance, water repellency, oil repellency, stain and stain repellency, dirt resistance, ease of cleaning, bond resistance, graffiti resistance
, etc.
