Abstract
Compositions and articles comprising a stress-resistant component comprising a thermoplastic component and an elongation component. In some examples, the stress-resistant component is comprised as an coating component covering at least one surface of a substrate, such as one comprising a medium density fiberboard (MDF), a particle board, an oriented strand board, fiberglass, a natural wood, a composite wood product, and a synthetic substrate. The stress-resistant component is preferably, though not invariably, produced by extrusion. The invention is also directed to articles, such as extrusion profiles, comprising the stress-resistant component, and methods of making such articles.
