NR and SR activator; semi-reinforcing and hiding pigment.


HT-Active
Zinc oxide
Hydro Technologies (Canada)
ï

High surface area ZnO; BET 40 m2; sp.gr. 5.6; cream to off-white powder; zinc content > 97%; Pb content <25 ppm

A highly dispersible zinc oxide especially suited for semi-transparent and latex compounds; its higher activity benefits compounds with reduced zinc oxide content; when used at higher levels, improves compression set, crosslink density and reduces cure time.


HTR
Zinc oxide
Hydro Technologies (Canada)
ï

High surface area ZnO; BET 30 m2; sp.gr. 5.6; cream to off-white powder; zinc content >97%; Pb content <25 ppm

Slightly lower in surface area than HT Active; highly dispersible zinc oxide especially suited for semi-transparent and latex compounds; its higher activity benefits compounds with reduced zinc oxide content; when used at higher levels, improves compression set, crosslink density and reduces cure time.


HT-10
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 8-11 m2; sp.gr. 5.6; cream to off-white powder

Medium surface area ZnO; NR and SR activator; semi-reinforcing and hiding pigment with higher activity; useful in adhesive formulations as a latex activator and supplemental gelling agent.
