UK's Oxford Advanced Surfaces Group Plc (OAS), the advanced materials company, has developed a new technology that promotes superior adhesion with a wide range of industrial epoxy adhesives. The Onto® adhesion promoter can increase adhesion to materials such as polyimides and PET polymers where epoxy adhesives on their own fail to achieve satisfactory bonding. Epoxy adhesives, though widely used, do not bond well with materials which are chemically inert or have low surface energy, according to the company. The Onto® adhesion promoters could fill in this void.
The Onto® adhesion promoters can be several nanometers to several microns thick depending on the application. They can be used with a broad range of substrates including polymers, inorganic materials and metals and can be applied with a choice of wet application processes. Potential applications for this new industrial adhesion promoter are within the hi-tech engineering, aerospace, automotive, electronics semiconductors, displays and printed circuit boards sectors. It can also be used in industrial packaging, industrial coatings, composites and laminates.
OAS uses proprietary highly reactive chemistry, Onto®, in combination with polymers and/or particles to provide solutions that deliver enhanced performance and enable new opportunities. Initial applications include advanced adhesion, anti-tarnishing of silver, anti-reflectance coatings and particle delivery in markets including advanced composites and laminates, electronics, lighting, displays and fast moving consumer goods.
