Hallco CAOP
Calcium hydroxide/DOP dispersion
The HallStar Co.
ï

Sp.gr. 1.05; (80% calcium hydroxide) finely dispersed in DOP; free flowing powder, dustless.

Recommended for mill and internal mixing; offers better dispersion and safety.


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.


HT-2C
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 4-7 m2; sp.gr. 5.6; cream to off-white powder

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


HT-3C
Zinc oxide
Hydro Technologies (Canada)
ï

General purpose ZnO; BET 4-8 m2; sp.gr. 5.6; cream to off-white powder

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.
