Abstract
A protective sealant composition that is useful for sealing a colorant to a substrate, such as carpet. The protective sealant composition is formulated such that, upon drying, the composition forms a topcoat on the surface of the substrate, with the topcoat having a hard component and a soft component. The composition provides a durable protection against color fading and resoiling to the applied colorant, as well as to the rest of the surface of the substrate. The composition also provides wear resistance to the carpet by reducing the amount that the widths of the top ends of carpet fibers increase when subjected to wearing.
