Characteristics of the Micronized Copper Preservative

Consumers have fallen in love with the lighter, more natural appearance of micronized copper treated products as well as their improved painting and staining capabilities. But YellaWood® brand products also boast improved corrosion characteristics and are approved for contact with aluminum*. In addition, they are long-lasting, durable, clean to the touch, have no objectionable odor, and provide protection from rot, fungal decay and termite attack. Outdoor exposure testing shows that products treated with micronized copper preservatives offer superior product benefits compared to other copper-based wood preservatives.

YellaWood® brand products are available in Southern Yellow Pine and South American Pine species and are available treated for Above Ground, Above Ground General Use, Ground Contact and Fresh Water Immersion applications. The preservatives used in the treatment process are registered by the EPA as a non-restricted use pesticide and do not require Proposition 65 labeling in California. Products treated with micronized copper preservatives, such as YellaWood® brand products, as described in ESR-2240 and ESR-1721 are building code compliant.
