ZINC OXIDE
GRADE 205H
Description & Uses
Grade 205H is a small particle size French Process, statistically controlled zinc oxide produced from zinc metal. This grade has a higher surface area and is used by the zinc chemicals, latex and plastic industries and in those applications where higher reactivity and moderate purity is required. Grade 205H is available with surface treatment (205HS) and in a pelleted form (205HP).
