Montreal, January 17, 2007 – In line with its ongoing efforts to innovate and develop new markets, Domtar today launched the first antimicrobial office paper available in North America. Designed to protect paper against the growth of bacteria, odors, fungus, mold and mildew, this product is specially treated with a silver compound that kills most bacteria that come into contact with it. Although conceived for general office use, the paper’s unique characteristics make it ideal for the healthcare, laboratory, hospitality, education and governmental sectors. Laboratory studies show that one bacterium can reproduce into 10 billion bacteria in just 10 hours.1 Independent laboratory tests on Domtar Antimicrobial Office Paper™ demonstrate a 99% reduction of MRSA (Methicillin-resistant Staphylococcus aureus) and K. pneumoniae.2 The paper also inhibits the growth of bacterial odors, mold, mildew and fungus while maintaining the antimicrobial features throughout its shelf life, making it ideal for archival purposes. Additionally, Domtar Antimicrobial Office Paper retains its antimicrobial properties even after printing and varnishing. Worldwide Trends “With the introduction of the Antimicrobial Office Paper product, Domtar is once again demonstrating its commitment to bringing innovative products to the market,” said Steve Barker, Senior Vice President, Pulp and Paper Sales & Marketing of Domtar Inc. “The development of this paper presents an opportunity to help reduce the proliferation of bacteria in office environments.” Given the significant increase in virulent bacteria such as MRSA over the past ten years, antimicrobial products are now sought throughout North America and, indeed, the world. Similar products exist in Europe and Asia and Domtar is the first company to bring an antimicrobial office paper to North America. Domtar Antimicrobial Office Paper is manufactured under a licensing agreement with SilverCo, a developer of antimicrobial-patented technology. The antimicrobial compound has been registered with the United States Environmental Protection Agency (EPA) and approved by the Food & Drug Administration (FDA).
