COADŽ 20 ZINC STEARATE

  
DESCRIPTION
COADŽ 20 Zinc Stearate is a high grade multi-purpose zinc stearate with superior heat stability. It has a moderately high bulk density and exhibits improved dispersion for faster and more uniform mixing. The low specific surface provides important advantages when controlling viscosity.

APPLICATIONS
  • Color Concentrates: COADŽ 20 Zinc Stearate improves pigment dispersion and reduces blending time needed to produce uniform mixtures. It also acts as a lubricant to improve melt flow and prevents sticking to extruder surfaces.
  • Powder Metallurgy: COADŽ 20 Zinc Stearate shortens blending cycles, gives higher apparent densities and better flow properties in the metal powder-lubricant blends, reduces injection pressure, and improves die life.
  • Rubber dusting: COADŽ 20 Zinc Stearate is used where thick, uniform coatings are desired on uncured slabs or especially tacky formulations.
  • Waterproofing: COADŽ 20 Zinc Stearate may be employed in concrete and mortar admixtures to impart water repellency and to improve flow and release properties of the dry mix.
STORAGE AND HANDLING RECOMMENDATIONS
Storage - Store at ambient temperatures away from sources of heat or from places of extreme moisture.
Fire - Use water from a safe distance, preferably with a fog nozzle.
Handling - Avoid contact with skin or eyes. Safety goggles are recommended.
Spills - Clean up immediately. Sweep up and discard in a closed container.
Disposal - Consult Federal, State, and Local regulations. Consult the telephone book or EPA for list of approved disposal companies.
Other - See MSDS for COADŽ 20 Zinc Stearate for additional health, safety, and environmental information.
PACKAGING
COADŽ 20 Zinc Stearate is packaged in 25 lb. and 50 lb. multiwall bags, unitized on non-returnable wooden pallets. Please contact your Norac sales representative to discuss your special packaging requirements.
