摘要： Cathodically depositable electrodeposition paint binders comprising the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, optionally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde. The binders have excellent corrosion resistance and crosslink to provide coating films at relatively low stoving temperatures without splitting off of substances harmful to the environment.

摘要： A temporary high-temperature-resistant dispersing agent, and a preparation and a use method thereof. The temporary high-temperature-resistant dispersing agent is a block high-molecular polymer prepared by a one-step reaction from polysiloxane containing an amino group. The prepared block high-molecular polymer may be directly used as a dispersant; the block high-molecular polymer may also be used as a basic formula and used as the dispersant after other auxiliary compositions are added; and the block high-molecular polymer may also be used in combination with one or more other dispersion auxiliaries and/or surfactants to meet dispersion requirements in various special occasions.

摘要： A lignin-modified phenol-formaldehyde resin for use as an adhesive for particulate wood products is disclosed which is prepared by reacting phenol and formaldehyde with an aqueous alkaline solution of an organosolv lignin. The organosolv lignin used in the formation of the resin is obtained from a pulping liquor prepared from particulate wood material from hardwood trees, aqueous polar organic solvent, and an acid catalyst. The resin allows for replacement of phenol or organosolv lignin at a level of up to 40% without detrimentally affecting its performance in terms of bonding strength or durability. The resin of the present invention is also superior to prior art lignin-modified resins in that it is low in sulfate, ash and sulfur residues, and thus will not give off distracting or harmful sulfur odors during resin preparation or hot-pressing of the adhesive and is unaffected and not solubilized by water.

摘要： Cathodically depositable electrodeposition paint binders comprising a mixture of (A) 95-50% by weight of the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, optionally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde; and (B) 5-50% by weight of an addition component which is substantially water-insoluble under the conditions of electrodeposition and being compatible with Component A. The presence of Component B in the binder provides increased resistance to corrosion, improvements in the surface quality of the stoved films, and enhanced crosslinking of the binder.

摘要： The production of amine resins having Mannich base groups which dissolve in water with the aid of a solubilizing acid is disclosed in which a dihydric phenolic organic compound, such as a bisphenol, is reacted in organic solvent medium with at least 3 moles of formaldehyde per mol of bisphenol to at least partially methylolate the bisphenol prior to other reactions. The at least partially methylolated product is then reacted with a stoichiometric deficiency of organic diepoxide, and then with monosecondary amine to provide Mannich base groups. The Mannich base-containing product is then reacted with additional epoxide-functional material.
