Abstract

Aqueous emulsions of heat reactive synthetic resins are made by mixing the resin and an emulsifying agent without other components and without heating, adding water during the mixing, and continuing the mixing and gradual addition of water until the water-in-resin emulsion first produced is converted into a resin-in-water emulsion. The resins may be phenol-formaldehyde, urea-formaldehyde, or alkyd resins, or those obtained according to Specifications 267,736, 293,453, and 324,025, [all in Class 2 (iii)]. A viscous resin obtained by reacting phenol, tung oil, hexamethylene tetramine, and phosphoric acid is kneaded with an emulsifying agent such as triethanolamine oleate, water being added slowly and continuously until phase inversion occurs. The emulsion obtained can be diluted to any desired degree. In general, emulsifying agents such as soaps, clays, casein-ammonia, or gum arabic are used in amounts of from 1--10 per cent of the weight of resin. Fillers, pigments, metal powders, and the like may be added to the emulsion, preferably while still in the water-in-resin state. Specifications 296,685 and 313,027 [both in Class 81 (i)], also are referred to.ALSO:Aqueous emulsions of heat reactive synthetic resins are made by mixing the resin and an emulsifying agent without other components and without heating, adding water during the mixing, and continuing the mixing and gradual addition of water until the water in-resin emulsion first produced is converted into a resin-in-water emulsion.
