Coatings World: January 2013

California led the regulatory charge this past year by proposing a ban on copper in pleasure craft coatings (Senate Bill 623), while simultaneously initiating a re-evaluation of cooper as an approved biocide in antifouling coatings (Department of Pesticide Regulations). In September 2011, the California State Lands Commission (CSLC) released a draft proposal to control biofouling on ships hulls entering California ports.

The California State Lands Commission (CSLC), operating under a statutory directive from the state Legislature to establish regulations "governing the management of hull fouling on vessels arriving at a California port or place" and "based on the best available technology economically achievable," proposed a biofouling rule for all ships greater than 300 gross tons that carry ballast water entering California ports. Released in September 2011, the proposal mandated "performance standards" with a ranking system to determine if a ship's hull is clean enough to enter California waters. The CSLC biofouling rule was akin to the International Maritime Organization (IMO) "Guidelines for Control and Management of Ships' Biofouling to Minimize the Transfer of Invasive Aquatic Species," which were adopted as an IMO Resolution on July 15, 2011 and were largely supported by the U.S. paint and coatings industry. However, the California proposal deviates significantly from the IMO guidelines in that it mandates the "performance standards" with a ranking system. Because of the difficulty in interpreting such a subjective scale, coupled with the fact that antifouling paints have never been subjected to such a system, the IMO did not incorporate performance standards into the international guidelines. The U.S. marine coatings industry, through ACA, commented on multiple drafts of the proposal, urging CSLC to delete the performance standards from its proposal and, instead, confine its provisions to those in the IMO guidelines. The U.S. marine coatings industry believes that, due to the international nature of shipping and in order to maintain a level playing field in the highly competitive marine industry (in 2010, U.S. shipments of marine coatings, including original equipment manufacturer and refinish applications, totalled 13.9 million gallons valued at $430 million), biofouling standards should be adopted consistently across the globe. The U.S. marine coatings industry maintains that vessels following the IMO guidelines that enter California waters will present a low risk for translocation of invasive species into California waters. California law requires that rules such as the biofouling rule be promulgated within a year. CSLC did not include the issue on the August or October agenda and therefore will need to begin the rulemaking process anew.

Control Technique Guideline (CTG) for Pleasure Craft Coatings

The pleasure craft CTG continues to inhibit the marine coatings industry as it is adopted in a patchwork fashion across the 50 states and local air districts. The PC CTG was finalized by the EPA in 2008 with little- to-no input from industry and is based on the South Coast Air Quality District's rule 1106.1. Because of the lack of consultation with coatings experts, the VOC levels of certain categories and the definitions provided in the CTG are problematic. Additionally, there is at least one crucial coating category that was not included in the PC CTG. Over the last several years the American Coatings Association has been lobbying individual states to modify their PC CTG (after all, the CTG only offers guidance to the states) to include the more realistic VOC levels, as well as adding the Antifouling Sealer/Tie Coat category, among other things. While some states are amending EPA's recommendations, others are adopting the CTG "as is." This is creating confusion not only within the manufacturing world — having to create different formulas for different jurisdictions — but also with customers. This year Maryland adopted a version of the PC CTG and Maine has just begun the rulemaking process to adopt the CTG. New York and Pennsylvania are expected to follow suit in the coming year.


 Press Release: January 2013

Britain's Health and Safety Executive has alerted users and suppliers of water treatment systems that use elemental copper they cannot use that method after Feb. 1, 2013, because as of that day it is prohibited by the EU. It will also be illegal to supply the copper needed for such systems, which add copper ions to water as a biocide.

"The action has been taken at EU Level under the Biocidal Products Directive because no manufacturer supported the use of elemental copper for use as biocides in these systems during a review period that ended in September 2011," the notice stated. "HSE's primary concern is that legionella control is not compromised. Businesses and organisations have a responsibility to manage the risks from legionella and it is essential that these duties continue to be met. In addition, HSE intends to pursue an 'essential use derogation' for use of copper in legionella control systems in the UK. We encourage users of these water treatment systems to contact the manufacturer to discuss a way forward."


 Press Release: January 2013

Tristel, the manufacturer of infection prevention, contamination control and hygiene products, announces that it has now received a licence from the Health Department of the People's Republic of China to import and sell the Tristel Wipes System.

The Tristel Wipes System is a practical and highly effective way to decontaminate and disinfect non-lumened medical devices. The system achieves high-level disinfection in less than two minutes. It comprises three individual wipes that perform the functions of cleaning the device, disinfecting the device and then rinsing it to remove any chemical residues before use on the next patient. It also incorporates a traceability process to provide the user with an audit trail. The Wipes System has been protected by patent in China since July 2011.

The Wipes System decontaminates flexible endoscopes used for ear, nose and throat investigations. Some of the major markets in which the Wipes System has established a significant presence are the United Kingdom, Germany, France, Italy, Russia and Australia.

Tristel's worldwide sales of the Wipes System in the financial year ended 30 June 2012 had increased by 56.6% to £3.4m (2011: £2.2m), and contributed to total sales of £10.9m across the Group.

Tristel CEO, Paul Swinney, commented: "We identified a number of years ago that there is a family of small heat-sensitive instruments that have been largely neglected by infection control companies. The instruments are short and simple in construction because they only have to reach into the smaller cavities of the body, like the nasal passage or the vagina. In contrast, our competitors have focused upon digestive and respiratory medicine where instruments have to be larger to reach the parts of the body that they need to investigate, for example the colon.

"We believe the Wipes System has already established itself as the 'gold standard' for the decontamination of these smaller instruments in the countries where it has obtained regulatory approval. With the licence we can now seek to replicate this success in China - the world's most populous and fastest growing healthcare market."

Tristel is a manufacturer of infection prevention and contamination control consumable products. The company's lead technology is a proprietary chlorine dioxide formulation and the Company addresses three distinct markets: (1) The Human Healthcare market (hospital infection prevention – via the Tristel brand), (2) The Animal Healthcare market (veterinary practice infection prevention – via the Anistel brand), (3) The Contamination Control market (control of contamination in critical environments – via the Crystel brand). The company's turnover was up 18% to £10.94m (2011: £9.29m)
