Abstract

312,650. Pfenning-Schumacher-Werke Ges. May 29, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Moulding resins.-Articles are produced from urea-aldehyde condensation products by subjecting to heat and pressure the material in the form of powder containing substances adapted to increase fluidity. Water up to 5 per cent by weight of the material is preferably employed; it may be introduced by moistening the dry powder, by drying the material until the water content is 5 per cent, or by adding salts or compounds containing water of crystallization, or which give off water. Alcohol, ketones or amines may be employed instead of water. Solid materials which melt, evaporate or sublime may be employed, or glycerine, or other m6isture absorbing substance. Pigments, filling materials, &c. may also be added. The invention includes also thiourea and derivatives of urea and thiourea.
