Resulting Properties
The above table shows a starting formulation for a UV 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. With this adhesive lamination can be done immediately after UV exposure. The formulation exhibits good adhesion to polyethylene, polyester, BOPP, polycarbonate, aluminum and steel.
