Abstract
The invention relates to a multilayered pultruded structure having a weatherable cap layer over a pultruded substrate, adhered with an appropriate tie layer. The structure provides improved weatherability and surface quality for pultruded structures. The invention is especially useful to provide a weatherable pultruded polyurethane, with an acrylic or styrenic cap layer. The weatherable polyurethane (PU) pultrusion of the invention provides an increased modulus over polyester pultrusions, making the weatherable PU pultrusion useful in commercial applications, and applications requiring a higher transverse modulus.
