Oxford Advanced Surfaces unveils its new solvent-resistant hydrophobic/oleophobic
coating technology

01 December 2011

OXFORD, England--(News Item) -- Oxford Advanced Surfaces Group Plc (OAS) has produced a solvent resistant oleophobic and hydrophobic coating system using its proprietary technology, Onto™ XL Highly Reactive Chemistry. The technology has been used to modify the wetting and surface energy characteristics of both glass and plastic substrates, but could also be utilised on other materials. A common approach for simultaneously imparting both hydrophobic and oleophobic functionality to a surface is to coat it directly with a fluoropolymer but there are often associated problems with the stability of the film towards solvents, especially on plastic substrates. Using Onto™ XL technology in conjunction with a fluoropolymer prevents delamination to result in an oleophobic/hydrophobic surface that is stable to solvent exposure.

The coating is applied in two layers from non-fluorinated solvents by common wet chemical processing techniques, giving it scope to be printed and therefore patterned. "This technology has the potential to be used in several applications but we believe that one of the most important markets will be organic electronics", claims Dr Sarah Vickers, Product Marketing Scientist at OAS. The use of Onto™ XL to anchor a coating to a substrate is not confined to fluoropolymers and has the potential to be used in conjunction with other types of coating.

Oxford Advanced Surfaces Group Plc (OAS) is an innovative Research & Development company delivering highly advanced materials solutions in optical coatings and highly reactive chemistry. Our proprietary technologies, Onto™ highly reactive chemistry and VISARC™ anti-reflective coatings, deliver performance-enhancing processes, opening up new markets for the most desirable high-performance advanced materials. Initial applications include adhesion promotion, surface treatment and anti-reflective coatings used in the large volume, high-growth markets of electronics, optics, displays and green energy.
