DARVAN® C-N
Ammonium Polymethacrylate for Ceramic Bodies
DARVAN C-N, an ammonium polymethacrylate, is used mainly in the electronic and specialty ceramics fields. It has little tendency to foam and produces slurries with unusually low viscosity.
PHYSICAL PROPERTIES
Molecular Weight: 10,000 to 16,000
Appearance: Clear to slightly opalescent amber fluid
Density at 25°C: 1.11 ± 0.02 Mg/m3
Weight per gallon: 9.2 to 9.2 lb
Percent solids: 25.0 ± 1.0%
Percent ash: 0.04% maximum – on wet weight
pH: 7.5 to 9.0
Viscosity at 25°C: 75 cps (maximum)
Solubility: Completely soluble in water systems
Stability: Stable in the presence of alkalies over a wide pH range
Burn out: DARVAN C-N begins to burn out at 450°F (232°C)
Storage: Freezes at -5°C. Protect from freezing
Partial freezing does not affect the product’s dispersing properties.
Keep container tightly closed to prevent evaporation.
APPLICATIONS: DARVAN C-N is recommended for use in the preparation of casting slips from high oxide electronic bodies where minimum sodium content is desired.
DARVAN C-N is also used to make slurries of ferrites.
