ZN 78 (Zinc Stearate)
ABOUT THE PRODUCT
ZN 78 (Zinc Stearate) is a white, fine powder metallic soap obtained by the reaction of stearic acid with zinc oxide or zinc salts.
Insoluble in water and with a slight waxy odor, this substance is widely used in the plastics, rubber, paint, cosmetics, and pharmaceutical industries due to its lubricating, mold release, and processing aid properties.
It also functions as a heat stabilizer in PVC production.
Thanks to its water-repellent properties, it is preferred in formulations that require protection from moisture.
