摘要:
Aminoplast or phenoplast moulding compositions are manufactured by passing an aqueous solution of a urea-formaldehyde resin, of an optionally phenol-modified melamine-formaldehyde resin or of a phenol-formaldehyde resin into a fluidized bed drier, by spraying the resin onto fillers and drying it. The compositions are used for crockery, household articles and technical components for the electrical industry.

The invention relates to the time-staggered utilization of tumor cells in combination with intact, preferably heterologous antibodies for the immunization of humans and animals.
摘要:
Disclosed are dispersions of fluorescent whitening agents which are suitable for the fluorescent whitening of coating compositions for coating paper or of fibre dispersions (paper pulps) in paper production.
摘要:
An epoxide resin moulding composition, comprising(a) a phenol or cresol novolak epoxide resin,(b) dicyandiamide as a hardener,(c) an accelerator suitable for hardening with dicyandiamide,(d) 20 to 70% by weight of calcium carbonate and(e) 10 to 60% by weight of glass fibres, the quantity of components (d) and (e) together not exceeding 80% by weight, relative to the total weight of the epoxide resin moulding composition,is suitable with advantage for the manufacture of commutators and slipring bodies.
