Two-component epoxy paste cures optically clear in thin sections

aster Bond Inc’s EP21NDCL is described as a two-component epoxy system that is formulated for a variety of sealing, bonding and coating applications in the optical, optoelectronics, electrical, aerospace and speciality OEM industries. This non-drip compound cures optically clear in thin sections, even though Part A is translucent and Part B is light amber, says the firm. It is easy to handle, with a one-to-one mix ratio by weight or volume. This ratio can be adjusted to deliver different properties. For example, a two-to-one mix ratio cures to create a structure that is more rigid, whilst a oneto-two mix ratio produces a flexible system. EP21NDCL cures at room temperature or more quickly at an elevated temperature. Upon curing, this epoxy features durable bonds with high tensile lap shear, tensile and compressive strength of 2600–2800 psi, 6500–7500 psi and 12 000–13 000 psi, respectively. It bonds well to many substrates, such as metals, composites, glass, ceramics, rubbers and plastics – particularly acrylics and polycarbonates. With a volume resistivity greater than 1014 ohm-cm, the compound offers impressive electrical insulation properties, claims Master Bond. It resists chemicals, including water, oils, fuels, acids, bases and salts. It also withstands rigorous thermal cycling over the wide service temperature range of -51°C to 121°C. EP21NDCL has a shelf life of a year at 24°C in its original, unopened container. 4

Threadlockers aid manufacture of speciality vehicles

enkel Ag & Co KgaA reports that its Loctite threadlockers are being used increasingly in the manufacture of high-performance speciality vehicles. In the USA, Local Motors, which focuses on low-volume manufacturing of open-source motor vehicle designs using multiple “microfactories”, faced two different challenges when it set out to build two very different vehicles – the Rally Fighter, a high-performance off-road machine, and the Strati, a 3D-printed electric car that had just 49 parts. To meet both challenges, it turned to Loctite threadlockers. Making sure that the Rally Fighter could withstand racing in extreme conditions without constant maintenance was a challenge. So was eliminating from the Strati many of the 25 000 or more parts found in a normal car. Off-road racers like the Rally Fighter are subject to jarring bumps and vibration that can shake loose even the sturdiest nuts and bolts. And every one of the Strati’s 49 parts is critical, so making sure those nuts and bolts stay tight was essential to realising Local Motors’ concept for the vehicle, says Henkel. Applying Loctite threadlockers to those fasteners gave Local Motors confidence that

once its mechanics tightened a bolt or screw, it would stay tightened, even under the challenging conditions of off-road racing. ‘People think about putting it together, but they do not think about how to make it stay there, and when we introduce them to Loctite they are exposed to a world they never knew before,’ said Jay Rogers, CEO, Local Motors, and the company’s co-founder.

Company News FSA responds to White House announcement on reducing emissions
I
n the USA, the Fluid Sealing Association (FSA), the leading trade association for American and Canadian sealing device manufacturers, has responded to the announcement made recently by the White House concerning the reduction of emissions. The White House announced that it will seek to limit methane emissions from existing sources in the oil and gas industry through forging a relationship with Canada to implement the historic Paris Agreement by developing mutual environmental control regulations. The FSA recognises the importance of addressing these challenges and believes sealing and containment device technologies can play an important role. It says cost-effective sealing device technologies, developed in the USA and Canada, offer a proven way to limit methane emissions from the oil and gas sector. The FSA and its members are committed to being a technical resource in addressing these issues. Its members welcome the opportunity to work with industry to drive emissions reductions in a positive way. (The full announcement by the White House can be accessed at the Web-site address given below.)
