Sealing Technology
LED-curable system is designed for highperformance sealing
M
aster Bond Inc of Hackensack, New Jersey, USA is offering a high-viscosity LED-curable system for high-performance sealing and encapsulation, and bonding and coating processes, used in the manufacture of disposable medical devices. Called LED403Med, this medical grade system passes the plastics test for USP Class VI biocompatibility and meets ISO 10993-5 cytotoxicity requirements, and withstands sterilisation methods such as gamma radiation, ethylene oxide (ETO) and various chemical sterilants, says the firm. Optically clear, LED403Med cures fully tackfree upon exposure to a 405-nm wavelength light source without any oxygen inhibition. In thinner sections, full cure can be achieved in 15–30 seconds. However, the rate of cure depends on the intensity of the light source, the thickness of the layer and the distance of the material from the light. It has a high viscosity, but remains flowable and can be used as an adhesive, sealant, coating and encapsulant in sections up to 1/8-inch (about 3.2-mm) thick. Once cured it is dimensionally stable and resists water and chemicals, including many acids, bases and oils. It bonds well to glass, polycarbonates, acrylics and other plastics, and metals. The adhesive is a competent electrical insulator and offers a solid physical strength profile. It is serviceable from –51°C to +121°C (–60°F to +250°F). Without contact with light LED403Med has a shelf life of six months in its original, unopened containers. It is available for use in syringes, and in 0.5-pint and pint measures, and quarts, gallons and five-gallon pails.

“Curve Gasket” supports design trend for lightweight parts
F
reudenberg-NOK Sealing Technologies recently developed an elastomeric static seal, referred to as the “Curve Gasket”. The company says that with greater stability, lower reaction forces and wider compression ranges, it helps minimise the amount of structural plastic required in engine covers. To achieve the dimensional stability and lower reaction forces essential for sealing lightweight thermoplastic covers, the Curve Gasket uses a combination of constant and undulated cross-sections that reduce loading. The undulated sections of the gasket use the same design principle as the corrugated waves used to stabilise metal sheeting. ‘This innovation helps to overcome the design challenges of traditional press-in-place gaskets. Its unique design offers greater stability in smaller grooves, which is ideal for the thermoplastic covers that we are seeing on new engine designs,’ explained Rafael Muchon, Global Product Marketing Director, Gaskets Division, Freudenberg. The gasket is fine-tuned to optimise its performance based on the sealing application. The design enables a shift in compression range to a higher level whilst reducing reaction forces, says the company. At elevated temperatures, which often cause expansion issues, the unique design also prevents the gasket from exceeding the void volume limit. ‘With today’s specifications, our customers are looking for cost-effective products across a range of different industries and applications. The Curve Gasket achieves perfect sealing whilst supporting efforts to use less material on components,’ added Rainer Joest, Global Manager, Gaskets Division, Freudenberg. Development of the Curve Gasket was led by the division’s European team. As the production process uses standard moulding tools and presses, it is now available to customers worldwide via Freudenberg-NOK’s network of manufacturing facilities in North America, South America, Europe and Asia.
