Resulting Properties
The above table shows a starting formulation for a flexo UV/EB cured laminating adhesive for versatile substrates. Upon curing, these adhesives offer a non-tacky film that provides excellent adhesive strength to a number of different substrates. However, when a specific application requires laminating opaque substrates, EB-curing adhesives may be necessary, since EB cure is not negatively affected by an opaque substrate.
