DESCRIPTION

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

Grade 102 offers high assay, very low impurities, and fine particle size with the highest French Process m2/g surface area (“SA”) available.

Grade 102 replaces grades Zinc Oxide LLC 800HSA and KADOX 911.

This product is also available with processing aid/surface treatment (grade 102T).

Grade 102T replaces grade ZOCO 102C, Zinc Oxide LLC 800HSA-T and KADOX 911C.

Grade 102 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 102 also meets the requirements of ASTM specification D79, 2002/95/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 grade is used where very low impurities are required, and where increased zinc oxide reactivity provides application benefits.
