Abstract: A fast curing high solids coating composition that is useful for coating the interiors of cans and a method of applying such high solids coatings to the interiors of food and beverage cans by spraying from a hot-melt spray gun are the subject of this invention; the coating composition is a blend of:A. a low molecular weight epoxy resin,B. a liquid nitrogen resin or phenolic crosslinking agent,C. a flexibilizing polyol,D. an inorganic or organic monomeric or polymeric acid which acts both as reactant and catalyst, and optionallyE. a surface modifier;And can be rapidly cured by heating at a temperature and for a time sufficient to substantially complete the crosslinking reaction.

Abstract: Aqueous can end sealant compositions substantially free from volatile organic solvents, setable at ambient temperatures and based upon relatively high molecular weight SBR latices are disclosed. The compositions are virtually free from the discharge of dangerous volatile organic solvents during the period of setting, yet become solid at ambient temperatures and are suitable for can formation by double sealing, particularly aerosol cans to contain food or non-food products.

Abstract: Biochemically active compounds e.g., proteins and particulate biological materials such as bacteria and viruses, are immobilized on a water-swellable or water-insoluble matrix by covalent bonding to a partially crosslinked polymer containing reactive groups capable of binding the biochemically active compound thereto.

Abstract: Proteins, particularly enzymes, are rendered insoluble in aqueous media by chemical activation of a polymeric support and crosslinking of the active proteins and the support by an inter-molecular bridging agent. The polymer which is used contains free hydroxyl or carboxyl groups and is halogenated and aminated in an organic solvent.

Abstract: In the production of sized paper and board using ketene dimer as sizing agent, there is used concomitantly with the ketene dimer a cationic polyelectrolyte so as to increase the sizing effect of the ketene dimer. The cationic polyelectrolyte is normally a dye fixative selected from water-soluble dicyandiamide-formaldehyde condensates. The cationic polyelectrolyte may be mixed with the ketene dimer so as to form a novel sizing composition which is preferably used in the form of an emulsion.

Abstract: Phenolic resin antipunk systems for thermal insulation, characterized by stability and a low level of volatile pollutants. The aqueous resin systems contain a resole component and an antipunk component. They are prepared by a three-step reaction which controls the degree of reaction, the molecular weight and the water tolerance of the resole component. Stability is promoted by inhibition of the crystallization of bis(4-hydroxy-3,5-dimethylolphenyl) methane.

Abstract: High efficiency stable aqueous emulsifiable resoles which contain low concentration of free phenol and free formaldehyde and cause substantially less pollution of the atmosphere than prior art resins. The resoles are prepared by a two-stage reaction which controls the molecular weight, water tolerance and the ratio of methylolated 2,2'-, 2,4'- and 4,4'-dihydroxydiphenylmethanes. Stability is promoted by inhibition of the crystallization of bis(4-hydroxy-3,5-dimethylolphenyl) methane.
