Today, treated wood products using the micronized copper preservative system represent the majority of treated wood sold into residential and agricultural markets in the U.S. The Koppers’ MicroPro technology is a patented system and is also sold in Canada, Europe, Scandinavia, New Zealand, Australia, Asia and in Central and South America. The Koppers’ micronized copper preservative system is an American Wood Protection Association (AWPA) standardized wood preservative. In addition, MicroPro treated wood products, as described in the International Code Council (ICC Evaluation Services Inc. ESR-2240), meet all major model building code requirements. Wood products treated with the MicroPro wood preservative can be used in above ground (UC3B), ground contact (UC4A) and critical ground contact (UC4B) end use applications.
The Koppers’ micronizing technology is also used to produce color pigment stains, mold inhibitors and other additives that benefit treated wood. The MicroPro treated wood process is the only wood preservative system with all these third party environmental and green certifications such as the Scientific Certification Systems’ Environmentally Preferable Product (EPP) Certification, Underwriters Laboratories GREENGUARD GOLD Certification,and the Home Innovation NGBS Green Certification. Since its commercial introduction in 2007, over 20 Billion board feet have been treated with the micronized copper preservative.
