Abstract: A hydrophilic plant growth substrate formed with a formaldehyde-free curable aqueous binder. The formaldehyde-free curable aqueous binder is formed in a process comprising combining the following components: (a) a hydroxy-containing polymer, (b) a multi-functional crosslinking agent winch is at least one selected from the group consisting of a polyacid salt(s) thereof and anhydride, and (c) a hydrophilic modifier. The hydrophilic plant growth substrate has excellent properties and is made in an environmentally friendly process.

Abstract: Methods of producing curable water-soluble organic-inorganic hybrid binder compositions that are based on the use of polyols containing a plurality of pendant hydroxyl groups and organooxysilanes. The curable water-soluble organic-inorganic hybrid binders prepared are useful in producing nonwoven products such as glass fiber products, polyester fiber products and mineral wool products.

Abstract: A formaldehyde-free curable aqueous composition containing polyvinyl alcohol, a multi-functional crosslinking agent, and, optionally, a catalyst. The composition may be used as a binder for non-woven products such as fiberglass insulation. The non-woven products are formed by contacting the formaldehyde-free curable aqueous composition with fibrous components and the mixture is cured to form a rigid thermoset polymer providing excellent strength and water resistance of the cured nonwoven product.
