Darvan 7 is a deflocculant and acts as a thinning agent in slips and as a general dispersing agent for slip clay bodies and glazes. Similar action to that of sodium silicate, however Darvan 7 will not erode plaster molds. Used to enhance the fluidity of casting slips and maintain or slow the shrinkage rate. Darvan 7 is typically preferred with porcelains and high iron content clay.
Slips that are prepared with Darvan 7 show little tendency to thicken on standing, which is why it is often used in glazes. Darvan 7 can also be added to joining slip, which allows the use of less water and results in less shrinkage at attachment points.
