Abstract

A three-part dry blended soluble mixture which includes a water soluble hydroxyl group bearing polymer, a covalent crosslinking agent, and a catalyst is made into an aqueous solution which is then applied to any underlying material of choice. After drying, the crosslinked polymer forms a material that is completely insoluble in water, thereby serving as a binder or tackifier. One additive that may be included with the dry blend is wood fiber in an approximate weight ratio of nine to one and thereafter this dry blend is combined with water where the three-part dry blend goes into solution while the fibers remain in suspension. This composition is then spray applied to any underlying material and upon drying, there is formed a bonded fiber matrix which is relatively strong and which has many applications such as for use as an erosion control/seeding material, a covering for landfills, or a covering for other particulate materials stored in an outside location. The insoluble polymer with or without the fiber will biodegrade over time in an outdoor environment.
