Abstract: A binder formulation is provided including water, a first polymer, and a second polymer. The first polymer is preferred to be a poly(carboxylic acid) and the second polymer is preferred to be a co-polymer containing both carboxylic acid and hydrophobic monomers. The first polymer can be polymers such as poly(acrylic acid), poly(methacrylic acid), poly(maleic acid), or poly(itaconic) acid. The second polymer is preferred to be an alternating copolymer of a monomer of a carboxylic acid and a hydrophobic monomer such as styrene, isobutylene, or n-alkenes. These binder formulations are particularly useful in making granulated powders in powder metallurgy and additive manufacturing.

Abstract: An aqueous metal surface treatment composition comprising the following ingredients: (A) an aqueous dispersion of a phenolic resin that includes a reaction product of (i) a phenolic resin precursor; (ii) a modifying agent, comprising a hydrocarbyl moiety bonded to at least one functional moiety that enables the modifying agent to react with the phenolic resin precursor; and at least one ionic moiety comprising an ionizable sulfur or phosphorous group; and (iii) at least one multi-hydroxyphenolic compound; and (B) optionally an acid where (iii) in (A) is optional where the reaction product contains two or more reactive phenolic methylol groups.

Abstract: Cyclic acetal derivative of a resole includes the reaction product of an ortho resole compound with a carbonyl compound or a carbonyl compound derivative. The cyclic acetal derivatives of phenolic resole compounds exhibit enhanced storage stability and can be readily activated at elevated temperatures to prepare phenolic based adhesives and coatings.

Abstract: An adhesion promoting composition for enhancing adhesion between an elastomeric substrate and a metal surface which, when applied at least in substantial contact with the metal surface, produces an elastomer-metal adhesive bond that withstands high temperature fluid and corrosive material environments and that can be applied without extensive pretreatment of the metal surface. The adhesion promoting composition comprises a phenolic resin derived from a first phenolic component, a second phenolic component, and a formaldehyde source, wherein the first phenolic component is a monohydroxy aromatic compound, a dihydroxy aromatic compound or a combination thereof, and the second phenolic component is a trihydroxy aromatic compound. A two-part adhesive composition containing a primer component and an overcoat component is also disclosed.

Abstract: A chemical formulation useful as a coating, primer or adhesive including a linear polyester polyurethane, a halogenated polyolefin, a phenolic resin, and a cross-linker. The formulation is preferably utilized as a two-component adhesive for bonding polymer blend-based thermoplastic elastomers to various substrates such as metal.
