Abstract: There is disclosed a resin-coated overlay for bonding to solid substrates, and which imparts improved waterproofing and chemical resistance to the resulting resin-coated overlaid solid substrate. Depending upon the desired end use of resin-coated overlaid solid substrate, the resin-coating may be modified to impart desirable surface features and/or characteristics. For example, additives such as waxes, oils, silicones, fluorocarbons and fatty acid compounds may be used to promote the release of concrete from forms made of solid substrates overlaid with the resin-coated overlays of the present invention. Moreover, resin-coated overlaid solid substrates may be produced having a surface which is suitable for painting and which accepts application of various tape products. Other modifications are disclosed which can be used to gain desirable cure speed, cost, and chemical/mechanical properties in the resin-coating.

Abstract: Lignosulfonate and sulfonated tannin compositions having magnetic properties which may be water soluble and a process for their preparation are described.

Abstract: Coating compositions prepared from phenolated lignosulfonates and polyunsaturated carboxylic acids are described.

Abstract: A clarification process using a water-soluble lignin-di-epoxide composition as a flocculating agent is described. The lignin-di-epoxide compositions are prepared by cross-linking of lignin with a di-epoxide.
