Zinc Oxide Dispersion
60% zinc oxide dispersed in water
Vanderbilt Chemicals, LLCï |
Density @ 25°C 1.98 Mg/m3; white dispersion; pH neat sample 9-11; total solids 2hrs @ 100-105°C 59.5-63.5%.
|
This dispersed form of zinc oxide permits its direct incorporation into latex compounds; Zinoxide at 0.5-6.0 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; a minimum of 5 phr zinc oxide is generally used for the compounding of CR latexes.
