DARVAN^® 7-NS

DARVAN^® 7-NS Dispersing agent is recommended for use in the preparation of casting slips made from whiteware and refractory compositions.  It is also used in glazes for rheological stability.  DARVAN 7-NS produces slips with a wide casting range.  Furthermore, the casting rate is not decreased to a marked degree, even though the slip is near the minimum viscosity point.  DARVAN 7-NS produces slips that show little tendency to thicken on standing, or to become thixotropic. Ware cast from these slips is very plastic and easy to “scrap”.
