Zinc Oxide Dispersion
60% zinc oxide dispersed in water
R.T. Vanderbilt, Company Inc.ï

White dispersion; total solids (2 hrs.@100-105ºC) 59.5 to 63.5%; density at 25ºC is 1.98 Mg

This dispersed form of zinc oxide permits its direct incorporation into latex compounds. Zinoxide at o.5 to 6.0 phr is used to activate the cure of NR,SBR and NBR latex compounds; zinc oxide acts as a vulcanizing agent in CR and XNBR latex; aminimum of 5 phr zinc oxide is generally used for the compounding of CR latexes.
