UV-curing epoxy resin adhesive for dome coatings

Vitralit UC 6686 is an epoxy resin based single-component adhesive, which cures rapidly under UV light. Developed especially for dome coatings, its high viscosity makes it ideal for automatic dispensing and application of doses in very close pitch precise patterns without spreading. The viscosity is such that it cures to a glossy curved dome which can optically magnify and enhance the appearance of a label or structure underneath it.

Once cured, Vitralit UC 6686 is  hard and scratch-resistant and has a transparent, brilliant high-gloss surface that does not yellow. It adheres especially well to glass, plastics and metals and has already been successfully used in the decoration of glass perfume bottles and product labels. When used as a protective coating the doming lends the surface a more refined, higher-quality look and feel while making it resistant to environmental influences.

The adhesive can be cured with both UV gas discharge lamps and UV LED lamps. Very good adhesion of applications over a large surface can be achieved with Hönle’s LED Spot 100 at a wavelength of 365 nm.
