Abstract
The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc., with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. Other embodiments involve affixing a container at least partially filled with superabsorbent polymeric powder to a substrate, placing the container proximate to the element, or affixing the container to a separate member. The products may be utilized for water and nutrient retention in combination with irrigation, erosion control, to direct plant root growth, and to clean up standing water and petroleum spills.
