White Seal 99.7%
White Seal 99.7% is a cost-efficient zinc oxide grade suitable for general industrial applications requiring stable quality and reliable performance.
Positioning
Designed for industrial markets requiring a low specific surface area (BET) and stable processing behaviour.
Produced using a balanced combination of Special High Grade (SHG) zinc and controlled secondary zinc units, this grade provides a cost-efficient solution for volume-driven applications such as rubber compounds, ceramics, industrial coatings and general chemical processes.
