New Technology Promotes Superior Adhesion With Wide Range of Industrial Epoxy Adhesives
(Nanowerk News) Oxford Advanced Surfaces Group Plc (OAS), the advanced materials company, announced today that it 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.
Marcelo Bravo, CEO at OAS said: “Epoxy adhesives are the most widely used structural industrial adhesives due to their high strength and resistance to harsh environments. However, they do not bond well with materials that are chemically inert or have very low surface energy which may require various forms of surface treatment to be effective. The Onto® adhesion promoters can bond materials with epoxy adhesives that are typically not epoxy friendly or allow the use of an epoxy system if using a more complex or costly adhesive”.
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.
The company would like to work with new partners who can license this technology to customise development for use in their specific products and processes".
Oxford Advanced Surfaces Group Plc (OAS) develops and commercialises advanced material solutions which are cost effective, simple to implement, and deliver valuable changes to the functionality of all kinds of surfaces via our platform surface modification technology. 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.
