Doming for Domed Labels
Protective coating of decorative articles, such as brooches, pins and key rings – so-called domings or dome coatings – is done by applying and curing a thick, optically transparent layer of adhesive. Domings are also applied to medals, fashion labels on glasses, adhesive labels and quality product labels, for example on whisky and perfume bottles. The doming lends the surface a more refined, higher-quality look and feel while making it resistant against scratching, yellowing and environmental influences.
A transparent epoxy resin-based adhesive is applied to create a doming for key rings.
The table below lists a selection of adhesives from Panacol that are used for doming applications. Further products and custom solutions are available on request.
