Hardening at the speed of light
UV/EB-curing adhesives have a major significance in the marketplace nowadays. They come into their own where extremely fast drying times are required and one of the components forming the joint is transparent to allow passage of the UV or EB rays – such as in the case of glass-bonded-to-metal components used in optical applications. Owing to the low emission levels of volatile organic compounds (VOC) produced, and a high level of cost-efficiency, radiation-curing is regarded as a “green”, sustainable technology that has above-average growth potential. As one of the leading manufacturers of acrylate monomers/oligomers and pre-formulated compounds for UV- and electron-beam-curing adhesives, we can provide precisely the knowledge and competence that our customers need. Indeed, we have specifically developed the Photomer® range to replace solvent-based adhesive products in the production of UV/EB-curing pressure-sensitive and lamination adhesives.
