Bayer plans to sell enamels business Bayer is planning to sell its worldwide enamels business, to be run as an independent company by the present management team. Negotiations are in progress with the global private equity investor Advent International and Chase Capital Partners. The move is aimed to streamline the company’s portfolio and focus on core businesses. Contact: Bayer AG, D-51368 Leverkusen, Germany; tel: +49-214 30-I; fax: +49-214 306 6328

A restriction to growth has been the toxicity of some products. Many formulations based on acrylate monomers are irritants to skin and eyes and must be labelled as hazardous materials. This has dissuaded some customers from using radiation-cured adhesives, notes Frost and Sullivan - but, concludes the agency, formulations have improved and prices are expected to fall.

EQUIPMENT MARKETING Environmental legislation favours cure by radiation Tighter environmental legislation in Europe, particularly aimed at restricting emissions of solvents, will stimulate strong growth in radiation-cured polymer systems, according to researchers Frost and Sullivan. The market, currently valued at $465.4 million, is forecast to reach $872.3 million by 2003, representing an average annual growth rate of 9.7%. Introduction of the European Solvents Directive, which is expected to be enforced tYly by 1999, is reducing the use of, and potential for, solvent-based products. Powder coatings using UV-curing technology will increase and diversify the market for radiation-cured polymer systems. Another factor is the relatively low cost of installing UV-curing equipment, compared with electron beam (EB) curing systems. But, as the number of EB systems available on the market has increased, so also has the popularity of this technology. Coatings are by far the largest sector of radiation-cured polymers, accounting for 82.8% of 1996 shipments. Inks were 10.5% and adhesives 6.7%.

Versatile extensometer for high temperatures, low cycles Said to be its most versatile high temperature strain gauge extensometer (for low cycle, fatigue, creep and stress relaxation testing at up to 1OOOC) is the new range, 2632 Series, introduced by Instron Ltd. A lightweight design, it is mounted by using ceramic cords that wrap round the specimen, providing secure, rapid, reliable and repeatable testing. Alternatively, the specimen can be mounted with leaf springs to a test piece. Designed to interface with Instron’s 8500 Plus Continuously Updated PID Controller, the 2632 Series has a low body mass, weighing just 20 grams (where some other products weigh about 40 g). This provides high resonance frequency, higher gain and increased dynamic performance. A further advantage is that the strain control loop can be increased, helping towards optimum performance and sharp response. The tester can measure strain to an accuracy off 0.5% of gauge length, with a deflection of only 10 grams/min and a strain grading of IS0 9513 O.S/ASTM ES3 B-2. Five models are available.
