DuPont Filaments to Demonstrate Impressive Advances at InterBrush 2012

Geneva, Switzerland, October 12, 2011

DuPont Filaments (DuPont) will demonstrate the significant gains made in all segments of its business, including new and refined products for abrasives, cosmetics, toothbrush and paintbrush applications, and a multi-million U.S. dollar investment in new plant capacity at Interbrush 2012. InterBrush will be held in Freiburg, Germany, and DuPont will be located at Stand 2.1.9.

Highlights will be DuPont™ Tynex® A HDP (high durability performance) filaments for enhanced sheet surface cleaning, DuPont™ Natrafil™ textured filaments improving on natural hair in cosmetic brushes, Tynex® StaClean™ for highest efficiency in antimicrobial toothbrush filaments, and DuPont™ Tynex®, Orel® and Chinex® paintbrush filaments in an extended range of inline dyed colors.

“Welcome to the Global Collaboratory”

The DuPont InterBrush exhibit will project the company’s new corporate theme: “Welcome to the Global Collaboratory,” reflecting the uniquely global nature of its brush filaments business and its ability to service customers locally in all key regions, exemplified by collaborative programs that have yielded better products to help customers become industry leaders.

“Our filaments business has advanced strongly on several fronts since InterBrush 2008, notably through double-digit growth in fine cosmetic brush filaments, supported by significant capacity expansions at our plants in China to serve customers globally and several product introductions and enhancements in other important brush markets, tailored to the latest market trends and evolving customer needs,” said Hok Hoh Wong, CEO and toothbrush segment leader, DuPont Filaments, based in Shanghai, China.

“With manufacturing facilities in China, India, The Netherlands and the United States, and marketing, sales and technical support in all the key market regions, DuPont is the only filament supplier that can offer such a depth of organization and the benefits of leveraging capabilities wherever the customer needs close collaboration in developing and commercializing high-performance brush products. We look forward to strengthening many of those special relationships at InterBrush 2012,” said Wong.

Natrafil® Challenges Natural Hair in Cosmetic Brushes

The DuPont Fine Filaments segment will showcase DuPont™ Natrafil®, a sophisticated synthetic filament for cosmetic powder brushes which combines the look and feel of natural hair with equal or better pick up and release performance, but without the imperfections. Natrafil® filaments complement a broad range of Tynex® filaments offering an almost limitless variation in flexibility, stiffness and softness for face, mascara and nail brushes.

The latest enhanced Natrafil® blends are expected to replace specific types of natural hair while retaining their essential characteristics and reflect intensive development work with makeup artists, cosmetic brands, brush manufacturers and cosmetics formulators since InterBrush 2008.

“DuPont™ Natrafil® today is a much-improved product and sets a real challenge to traditional natural hair brushes. The market is telling us that the product is right on trend, especially in anticipating the big return to popularity of twisted filament mascara brushes. Cosmetics are a dynamic growth market and we are seeing increased demand for our fine filaments, with particularly strong takeup in nail and facial cleaning brushes,” said John Hackney, DuPont Fine Filaments segment leader, based in Wilmington, Delaware, USA.

StaClean™ — Highest Efficiency in Antimicrobial Toothbrush Filaments

DuPont™ Tynex® StaClean™ filaments will headline the company’s offerings to the major toothbrush brands at InterBrush 2012. New since the 2008 event, StaClean™ filaments contain antimicrobial additives to inhibit the growth of bacteria. According to DuPont, and as supported by independent testing, StaClean™ has been shown to exhibit the highest efficiency in antimicrobial filaments, in addition to being fully compliant with the U.S. Environmental Protection Agency (EPA), the U.S. Food and Drug Administration (FDA) and the European food contact requirements.

“Third party testing of DuPont™ Tynex® StaClean™, demonstrated that the amount of Escherichia coli and Staphylococcus aureus, representative of common bacteria, recovered over a 24 hour period, using a modified test method of ASTM E 2149, was 76 percent and 96 percent lower respectively for StaClean™ compared with the control sample of a leading competitive antimicrobial toothbrush filament,” said Wong.

Efficacy of StaClean™ technology against these two bacteria also has been found to meet the technical specifications of industrial associations such as the China Industry Association for Anti-microbial Materials & Products (CIAA).

“StaClean™ technology is a shining example of DuPont’s focus on innovations that improve toothbrush performance, enhance dental health and well-being, and make a strong visual impact on the end-consumer.

Tynex® StaClean™ strengthens DuPont’s broad range of FDA-compliant filaments for the oral care industry, sold under the Tynex® and Herox® trademarks in a range of colors and sizes for manual and electric toothbrushes, as well as inter-dental brushes.

Global Growth for Tynex®, Orel® and Chinex® in Premium Paintbrushes

At InterBrush 2012, DuPont will demonstrate why it is a significant player in the global paintbrush market with Tynex® and Chinex® nylon, and Orel® polyester tapered filaments for premium paintbrushes, and will reveal the latest color capabilities of its inline dyed process.

The broad range of DuPont paintbrush filaments offers many options in shape and taper control, and includes DuPont Solid Round Tapered (SRT), Q and T tapered, and specialty filaments. All offers the consumer and professional painter superior pick up and less water absorption for smooth, even paint release over time.

“The use of Tynex®, Orel® and Chinex® in the premium paintbrush market continues to grow globally. While traditionally confined to the North American market, paintbrush manufacturers around the world are now expanding their paintbrush product lines to include brushes formulated with these products,” said Thomas Vichich, DuPont Filaments Wilmington-based paintbrush segment leader. “Although the inline dyed process was relatively new when it was introduced at InterBrush in 2008, DuPont has developed the technology and now offers a range of standard inline dyed colors that allow paintbrush manufacturers to vary the colors in their formulations without having to do batch dye at their manufacturing facility, saving them time and cost.”

In 2009 and 2010, the DuPont business funded two market research studies in North America and France in order to understand the buying characteristics of do-it-yourself painters who wanted professional results. The results of the study have been shared with paintbrush manufacturers through industry meetings and trade magazine articles.

Key findings revealed that these serious painters were willing to pay for a professional quality brush to achieve “time after time” durability, cleanability and performance. The combination of these three attributes can positively affect the useful life of a paintbrush, in some cases extending lifetime to as long as 20 years. The specific benefits of paintbrushes made with Tynex® filaments, which appealed to the survey samples of male and female painters, were excellent paint pick up and release, cleanability with just soap and water for continuous reuse and superior abrasion resistance over time compared to natural bristles. The full results of both surveys are available on request from DuPont Filaments.

New Tynex® A HDP to Lead Developments in Abrasive Filaments

DuPont will demonstrate new performance levels in abrasive filaments at InterBrush 2012, with new industrial Tynex® A HDP filaments for sheet steel surface cleaning applications, Tynex® A ceramic filaments to deburr alloy parts and textile fabric sueding, and Tynex® A diamond grit filaments for granite surface "leather finishing." In addition, the company will reveal development of a new grit-loaded filament for the silicon ingot polishing process used in the photovoltaic industry.

Tough and durable DuPont™ Tynex® A abrasive filaments for industrial and floor care brushes are impregnated with silicon carbide and aluminum oxide abrasive grit particles for fast and easy deburring, cleaning and polishing. They combine chemical resistance, aggressiveness and durability, maintain their stiffness when wet, yet are flexible enough to maintain contact with, and ensure proper abrasion of, every surface and crevice.

“Our development of DuPont abrasive filament products tracks industrial trends very closely. As an example, we are seeing a recent increase in the severity of applications, with industries asking for more efficient deburring and polishing, and longer life in brush performance. Also, new applications are emerging that require more powerful abrasive tools. As a result, our Tynex® A ceramic and diamond grit-based products are becoming popular, in addition to the traditional silicon carbide and aluminum oxide grits,” said Sam Zhong, abrasive segment leader, DuPont Filaments, Shanghai.

“We have responded to demands from steel mills for a product specifically designed for longer lifetime in surface cleaning of sheet steel. The result is Tynex® A HDP filament, to provide high-durability performance in tough steel process applications. During exhaustive testing at DuPont, the new filaments exhibited enhanced remained impact fatigue and resistance to brushing motion during long-term exposure to strong acid solution at 85°C, compared to standard filaments. Remained break load of Tynex® A HDP filaments — a measurement of tensile force remaining after long-term exposure to strong basic solutions at 90°C — also was significantly better.”
