Abstract

1308762 Desiccants LENINGRADSKY TEKHNOLOGICHESKY INSTITUT IMENI LENSOVETA and LENINGRADSKOE OBIEDINENIE ELEKTRONNOGO PRIBOROSTROENIA SVETLANA 12 Jan 1971 1423/71 Heading B1L [Also in Division C3] A desiccant composition comprises 20-60 weight percent of a zeolite, e.g. NaA zeolite, and 40-80 weight percent of a thermosetting polymer, e.g. an epoxy, phenolformaldehyde or urea-phenol-formaldehyde resin. The composition may be formed on the inner surface of a hermetically sealable container by the application to the surface of a solution of the resin which contains the zeolite in suspension and optionally a plasticizer and a curing agent for the resin.
