Abstract
Polymeric sheets of the invention comprise sequential layers as follows: a topcoat layer, a polyurethane-based carrier layer, and an adhesive layer. The polyurethane-based carrier layer is formed using essentially no chain extender having a molecular weight of 350 grams/mole or less, resulting in a relatively low storage modulus polymeric sheet. Such polymeric sheets are particularly useful for application to surfaces having a concave topography.
Claims19
A polymeric sheet comprising sequential layers as follows:
- a topcoat layer;
- a polyurethane-based carrier layer, wherein essentially no chain extender having a molecular weight of 350 grams/mole or less is used in formation of the polyurethane-based carrier layer;
- and
- an adhesive layer.
