According to Master Bond, it can be used for sealing, coating and encapsulating, especially for small to medium-sized castings where a low coefficient of thermal expansion (CTE) is required. EP30LTE-2 is said to be a highly dimensionally stable epoxy system with low linear and volumetric shrinkage upon curing. The compressive strength of the cured material is 24,000-26,000 psi and its CTE is 10 -13 × 10 -6 /in/in/°C. It is a reliable electrical insulator featuring volume resistivity of more than 1015 ohm-cm. EP30LTE-2 meets NASA low-outgassing specifications and features a combination of physical properties that make it viable for applications in aerospace, optical, electronic and specialty OEM industries where these requirements are critical. EP30LTE-2 is a two-part epoxy that obtains optimal properties when cured overnight at room temperature followed by a heat cure for 2-4 hours at 150-200°F. The system offers moderate flow character- istics with a mixed viscosity that ranges from 70,000 to 100,000 cps. » MOLDMAKING MATERIALS & EQUIPMENT Filament winding system targets small-series and manual production Roth Composite Machinery (Steffenberg, Germany) announced on Aug. 2 the launch of its new Type 1-ECO filament winding machine for manual production cells in the field of filament winding technology. According to Roth, the newly developed Type 1-ECO is a cost-efficient model for small series as well as manual production processes. The machine is designed for applica- tions comprising a low product complexity or for the entry into the field of filament winding. The Type 1-ECO machine features a modular concept of up to four seperately driven spindles. A maximum of four winding axes and two length variants (4,000 mm and 10,000 mm) are configurable. According to Bernd Fischer, sales director for Roth, "Due to its unique flexibility, our customers have the possibility to extend the machine cost-efficiently and can adapt it to increasing demands. The machine grows with new production requirements and individual tasks." NEW PRODUCTS
