Darvan No. 7 Dispersal Size:1 litre making it ideal for acceptingDarvan No. 7 is used to disperse ceramic suspensions to minimize their water content. It is an alternative to the long popular sodium silicate. About twice as much is required but Darvan No. 7 does offer a number of advantages. Typically soda ash is not needed as a complement and Darvan No. 7 does not attack plaster molds. In addition slurries are much less sensitive to over deflocculation and are more stable. It is thus easier to reprocess scrap.
