OAS Introduces UV-Curable Adhesion Promotion System at Advanced Engineering 2017

24 October 2017

Oxford Advanced Surfaces (OAS) is introducing a new adhesion promotion surface treatment that can be cured using UV light.

OAS has developed a range of versatile and reliable Onto surface preparation treatments that improve the adhesion of epoxy and polyurethane coatings to composites, engineering plastics and difficult-to-bond substrates. While using heat is a common and effective way of curing its surface treatment solutions, the company has acknowledged that some material applications cannot be cured in this way. This can be for a number of reasons, such as customers not having the equipment to heat their component up to 110°C, or for materials in which the glass transition temperature (Tg) is too close to the curing temperature. Therefore, OAS embarked on a product development programme to create a new Onto solution that can be cured either using a drying step, followed by UV light treatment, or by using a traditional heating method, if necessary.

“As the demand for lighter and higher performing materials increases across various applications, so does the need for creative products that make them easier to process and able to perform to a high standard," OAS Technical Manager Jon-Paul Griffiths explains. “We have used our surface chemistry expertise to develop the first solution of its type that can be completely cured using only UV light after a drying step. This will give customers more flexibility during the materials processing stage and will also increase the scope of the materials that can be surface treated for painting or lacquering.”

As with all the surface treatment solutions in the OAS range, the UV-curable product removes the need for sanding, abrasion and plasma treatments; can modify a wide range of substrates with a single product (CFRP and polyamide); works with virtually all epoxy and polyurethane-based coatings; is a simple wet chemistry sprayable system that contains no harmful aromatic hydrocarbons; and is clean and dust free.

"Our brand new, UV-curable system is suitable for use in a wide range of industries from automotive and aerospace, through to sports goods," says OAS Business Development Executive Terence Warmbier. "The product has successfully come through a period of stringent testing and, because it can be applied to the substrate both quickly and easily using a spray gun, we expect there to be considerable interest from customers who are facing adhesion and coating challenges and therefore searching for a solution that is effective, scalable and easy to process."

OAS will exhibit on Stand N112 at Advanced Engineering 2017 on 1-2 November in Birmingham, UK.
