A method for the production of amino and phenoplast of press masses with the use of a duennschichtverdampfers or of a roller drier

摘要

Aminoplast or phenoplast compositions are manufactured by drying an aqueous solution of a phenol-formaldehyde resin, a urea-formaldehyde resin or an optionally phenol-modified melamine-formaldehyde resin in a thin layer evaporator or roller drier. The compositions are used for the manufacture of crockery, household articles and technical components for the electrical industry.
