    • A two-part adhesive is provided wherein the first part comprises a stable aqueous alkaline monohydroxylic phenolic resole resin solution containing a methylene donor such as oxazolidine or a methylolurea and the second part comprises a stable resorcinolic resin precondensate having a shortage of formaldehyde and optionally containing a catalyst such as an ester functional compound for the resole resin. The resin in each part exhibits viscosity stability of an unmodified resin until mixed with the other part wherein the methylene donor, of the first part catalyzes the resorcinolic resin of the second part and the catalyst, when used, of the second part catalyzes the monohydroxylic phenolic resole resin of the first part. The adhesive finds utility in the production of structural lignocellulosic panels.

    • Discloses compositions of urea dissolved in aqueous, polymerizable phenolic resole resins, wood-product laminated composite products produced with such resins, with or without the urea, and methods for the production of wood-product laminated composites with such resins. The resins contain the alkaline polymerization product of (a) formaldehyde polymerized with phenol and aliphatic hydrocarbylphenol or (b) aliphatic hydrocarbylphenol dissolved in the resin containing the polymerization product of phenol and formaldehyde, wherein the hydrocarbylphenol has from 9 to 17 carbon atoms in the hydrocarbyl group and the quantity of hydrocarbylphenol is from about 0.2% to 5% based on the weight of the aqueous resole resin. Wood-product laminate composites bound with the above resole resin, after curing, exhibit unexpectedly low water absorption, good internal bond strength and reduced thickness swell properties.
