DESCRIPTION

Our Zinc Oxide product is a brilliant white powder manufactured by the French (Indirect) Process.

Grade 101 offer medium-high m2/g surface area (”SA”), high assay and very low impurities.

Grade 101 replaces grades ZOCO 100, Zinc Oxide LLC 800H, and KADOX915.

This grade is used where lower impurities are required, and where increased zinc oxide reactivity provides benefits such as in stearates and other zinc chemical applications.

Grade 101 meets GMP 21CFR110, is USFDA Approved as GRAS (Generally Recognized As Safe) at 21cfr182.8991 and is authorized by the USFDA for use wherever GRAS is approved including food contact in rubber, plastics, and coatings.

Grade 101 also meets the requirements of ASTM Specification D79, 2002/29/EC Restriction of Hazardous Substances Directive (RoHS) for heavy metals and Waste Electrical and Electronic Directive (WEEE), and other regulations where high quality zinc oxide is required.

This product is also available in pelleted form (grade 101P), and with processing aid/surface treatment (grade 101T).
