    摘要: A self-emulsifiable polyisocyanate mixture having a hexamethylene diisocyanate monomer content of not more than 1.0% by weight and an average NCO functionality of 2.0 to 3.7 obtained by subjecting hexamethylene diisocyanate to urethanation with a branched dihydric alcohol having overall 4 to 35 carbon atoms, of which 2 to 33 carbon atoms are a total number of the carbon atoms possessed by one or more branches, a hydrophilic surfactant having one or more active hydrogen atoms capable of reacting with NCO group and 3 to 90 alkylene oxide units, an aliphatic compound having one or more active hydrogen atoms capable of reacting with NCO group and 8 or more carbon atoms and an unbranched glycol having 1 to 10 carbon atoms; uretdione-forming reaction; and isocyanurate-forming reaction. Said self-emulsifiable polyisocyanate mixture is excellent in compatibility, dispersion stability and NCO group-stability and can be combined with water or a water-soluble resin and/or an aqueous emulsion, and if necessary, an additive to provide an aqueous coating or adhesive composition excellent in heat resistance, workability, coating film appearance, weather resistance and adhesion to substrate.

    摘要: Improved granular cocoa which is sufficiently dense and stiff but nevertheless is readily soluble in water, even in cold water, can be produced without using any binder by subjecting a cocoa powder of which fat content is 12-29% to compression, feeding the compressed powder to a roller press thereby forming small plate-like agglomerates which are 0.5-3 mm thick, and crushing and sifting the agglomerates to obtain 10-30 mesh granules of cocoa. The physical properties of the cocoa granules are further improved by ageing the granules at temperatures below about 27.degree. C., most preferably at 15-25.degree. C., for a few hours to several days. the starting cocoa powder may have been added with powdered sugar and/or milk.
