Coated zinc oxide powder and coated zinc oxide powder-containing composition

摘要

Coated zinc oxide powder comprises zinc oxide particles and a layer of a coupling agent formed on the zinc oxide particles. The coated powder may be incorporated into resin compositions or oil and fat compositions, directly or in the form of an additive which comprises the powder as an effective component. The coated zinc oxide powder shows excellent functions as an ultraviolet-absorber, an antibacterial agent, a moldproof agent and a deodorizing agent in these resin compositions and oil and fat compositions and can inhibit any deterioration of these compositions.
