EXTRUSION COATING OF ELONGATED SUBSTRATES

摘要

The present disclosure relates to extrusion coating systems, extrusion coated substrates, and processes for making the same. In some aspects, extrusion coating systems as described herein may include an at least partially insulated outlet wall, which may facilitate production of coated substrates exhibiting a very desirable surface texture and appearance. Coated substrates of the present invention may be utilized in a variety of end applications, including, but not limited to, interior and exterior construction materials for homes, buildings, and furniture.

主权项

1. A coated article comprising:
an elongated substrate; and a thermoplastic resin coating extrusion coated onto said substrate, wherein said coated article is a water-quenched article that has not been subjected to a post-quench treatment step and has an average Rmax surface roughness of not more than 30.
