A binder, neutralizable with bases, for producing siccativated aqueous coating agents, based on a polydiene resin partially crosslinked with bis(2-oxazoline), with an acid number of 50 to 100, that is obtainable by anhydrous reaction of A. 40 to 80 wt % of one or several polydiene oils with a weight-average molecular weight of 300 to 5000, B. 5 to 25 wt % of one or several .alpha.,.beta.-ethylenically unsaturated carboxylic acids, C. 1 to 10 wt % of one or several bis(2-oxazoline)s and D. 0 to 20 wt % of one or several physically curing resins and/or ethylenically unsaturated monomers, transfer into an aqueous medium and reaction with E. 1 to 40 wt % of one or several ethylenically unsaturated monomers in presence of an oil-soluble, free-radical-forming polymerization initiator and optionally a polymerization regulator, wherein each of the above percentages by weight relates to the sum of components A, B, C, D, and E. A process for production of the binder and its use in aqueous coating agents.
An adhesive composition which can be formulated to have low or substantially no VOC emissions is provided. Adhesives in accordance with the invention can be formulated as high solids, one-part, reactive, cross-linked adhesives. This can be achieved by utilizing amide-ester-acrylate reactions or reactions with any other carboxylated polymers. Adhesive compositions in accordance with the invention can include oils, such as various drying oils and similarly acting polymers, co-polymers, and fatty acids. Adhesives in accordance with the invention can also include various hydrocarbon resins, particularly crosslinkable hydrocarbons having a melting point in the range 70.degree. C. to 140.degree. C. Cross-linking agents, such as materials with pendant oxazoline groups are also advantageously included. Various other mixing, flow and other handling ingredients can also be included.
A composition and method which exhibits enhanced moisture sealing properties, suitable for use with flooring materials, such as concrete, and flooring installations, such as carpeting, wood, tiles, etc. are provided. The composition is preferably non-water-based and can form a non-aqueous barrier coating on the flooring substrate, and most preferably provides a desirable pH and blocks migration of alkaline salts through the substrate.
