Dow improves LSE technology
materials news
Aerovac supports UK boatbuilder AEROVAC Systems Ltd, a UK specialist in the development and distribution of composite process materials for the advanced composites industry, is developing ways to better serve its customers, including providing consignment stock to help save time and money. One of Aerovac's major marine customers is Green Marine, which manufactures three classes of RNLI lifeboats. Aerovac has reacted to the changing needs of Green Marine by providing consignment stock, which is said to save time and labour as monthly deliveries are monitored by an Aerovac representative. As the rep is on-site, the reaction
times are short and top-up arrangements can be made in less than 24 hours. Having consignment stock is said to prevent costly and wasteful 'down time' as product spares are available immediately and do not have to be ordered. Two months worth of stock is usually carried, which can then cover any increase in production. There is no limit on what stock a major customer holds as it only pays for what it uses. Aerovac also offers exclusive materials and sizes, spedfic to customer requirements or to suit a particular job. Aerovac; tel: +44-1274550500; website: www.aerovac. com.
Dow improves LSE technology AN IMPROVED styrene suppressant technology designed to help composite fabricators meet anticipated new regulatory standards is being introduced by Dow Chemical. The company says that Derakane epoxy vinyl ester resins made with this technology will provide the performance the industry expects with substantially less styrene emitted during fabrication and cure. Dow notes that flow hoods and closed moulding processing are only partial solutions to reducing styrene emissions. There are m a n y processes, such as open-air fabrication of larger parts, that will need alternative approaches to remain cost effective while meeting stricter emission levels under the Environmental Protection Agency ( E P A ) ' s Maximum Achievable Control Technology (MACT) proposal. Styrene suppressant products offering similar viscosity and corrosion performance to today's vinyl ester resins are one area Dow is working on. The company says it has achieved a balance of corrosion performance and styrene suppression for multi-layer parts through enhanced wax
suppressant capability. This is said to almost eliminate the degradation of interlaminate adhesion that can reduce the structural integrity of the final product. The suppressing agent used in vinyl ester resins will form a thin film during the curing stage that stops contact with the atmosphere, thus hindering styrene evaporation. Dow claims to have overcome the former challenges associated with this method during cure and promises to develop products that offer outstanding adhesion, corrosion performance and processability with considerable reduction in styrene emissions during cure. The company reports it is working on additional low styrene emission resins and plans to commercialize them soon. These new products are designed to help customers continue to produce high quality fibre reinforced plastic (FRP) parts while minimizing investment in abatment and control systems otherwise required to meet the pending emissions requirements.
